  • WPF Prism's delegatecommand not refreshing

    - by gkar
    I am building wpf edit form, that has two buttons, BeginEdit and Save And the form is bound to ViewModel that inherits from Prism's NotificationObject. There is a property called IsReadOnly And there are two commands that are Prism's DelegateCommands BeginEdit command and save command The code is here private DelegateCommand _beginEdit; public DelegateCommand BeginEdit { get { return _beginEdit ?? (_beginEdit = new DelegateCommand(() => this.IsReadOnly = false , () => IsReadOnly)); } } private bool _isReadOnly; public bool IsReadOnly { get { return _isReadOnly; } set { _isReadOnly = value; RaisePropertyChanged("IsReadOnly"); } } private DelegateCommand _saveEdit; public DelegateCommand SaveEdit { get { return _saveEdit ?? (_saveEdit = new DelegateCommand(() => this.IsReadOnly = true , () => !IsReadOnly)); } } So, as you see, the command will set IsReadOnly property to true or false, and CanExecute should get its value from the same property as well. It works when I start the form. But after I press BeginEdit, the buttons stays as the same, and the canExecute is not reflecting the new value of IsReadOnly

  • Radiobuttons and jQuery

    - by SnowJim
    Hi, I have the following radiobuttons rendered in MVC : <div class="radio" id="ModelViewAd.TypeOfAd"> <input checked="checked" id="ModelViewAd.TypeOfAd_Ad" name="ModelViewAd.TypeOfAd.SelectedValue" type="radio" value="Ad" /> <label for="ModelViewAd.TypeOfAd_Ad">Annons</label><br> <input id="ModelViewAd.TypeOfAd_Auktion" name="ModelViewAd.TypeOfAd.SelectedValue" type="radio" value="Auktion" /> <label for="ModelViewAd.TypeOfAd_Auktion">Auktion</label><br> </div> Now I need to hide the id=divEndDate element based on the value on the radiogroup. I have tried this : $(document).ready(function () { $("#TypeOfAd_Auktion").click(function () { if ($(this).checked) { $("divEndDate").css("visibility", "visible"); } else { $("divEndDate").css("visibility", "hidden"); } }); $("#ModelViewAd.TypeOfAd_Ad").click(function () { if ($(this).checked) { $("divEndDate").css("visibility", "hidden"); } else { $("divEndDate").css("visibility", "visible"); } }); }); Now one of these are triggered when switching between the radio buttons? How to solve this?

  • Oracle User definied aggregate function for varray of varchar

  • Is there any class in the .NET Framework to represent a holding container for objects?

    - by Charles Prakash Dasari
    I am looking for a class that defines a holding structure for an object. The value for this object could be set at a later time than when this container is created. It is useful to pass such a structure in lambdas or in callback functions etc. Say: class HoldObject<T> { public T Value { get; set; } public bool IsValueSet(); public void WaitUntilHasValue(); } // and then we could use it like so ... HoldObject<byte[]> downloadedBytes = new HoldObject<byte[]>(); DownloadBytes("http://www.stackoverflow.com", sender => downloadedBytes.Value = sender.GetBytes()); It is rather easy to define this structure, but I am trying to see if one is available in FCL. I also want this to be an efficient structure that has all needed features like thread safety, efficient waiting etc. Any help is greatly appreciated.

  • passing string to a AJAX/JSON function

    - by Mikey1980
    I’m having trouble getting a AJAX/JSON function to work correctly. I had this function grabbing value from a drop down box but now I want to use an anchor tag to set it's value. I thought it would be easy to just use the onClick event to pass string to the function I was using for the drop down box but it doesn’t do anything. I’m stumped! Here how I set it up: 1st I add an onClick event… <a href="<?php echo Settings::get('app.webroot'); ?>?view=schedule&action=questions" onmouseout="MM_swapImgRestore();" onmouseover="MM_swapImage('bre','','template/images/schedule/bre_f2.gif',1) onclick="assignCallType('testing')";> 2nd I check main.js.php function assignCallType(type) { alert(type); //just for debugging new Request.JSON({ url: "ajax.php", onSuccess: function(rtndata,txt){ if (rtndata['STATUS'] != 'OK') alert('Error assigning call type to call'); }, onFailure: function (xhr) { alert('Error assigning call type to call'); } }).get({ 'action': 'assignCallType', 'call_type': type }); } 3rd Ajax.php: the variable is back in PHP and values don’t get added to the db, but I also didn’t get the alert from main.js.php if ($_GET['action'] == "assignCallType") { if ($USER->isInsideSales()) { $call_type = $_GET['call_type']; $_SESSION['callinfo']->setCallType($call_type); $_SESSION['callinfo']->save($callid); echo json_encode(array('STATUS'=>'OK')); } else { echo json_encode(array('STATUS'=>'DENIED')); } } Any idea where I am going wrong. The only difference between this and the working drop down is how the function was called, I used onchange="assignCallType(this.value)".

  • Better way to implement custom views in a listview with simpleadapter?

    - by jonaz
    I have a value called tags which is a comma separated list of words. I want to put this into nicely designed "tag-buttons". The below works. However the line ((LinearLayout) view).removeAllViews(); seems like an ugly fix for not adding the tags multiple times every time adapter.notifyDataSetChanged(); is called after i load more rows with a setOnScrollListener() Any suggestion to "best practice" here, or at least a more good looking solution? adapter = new SimpleAdapter(activity,data, R.layout.list_transactions, new String[] {"comment", "amount","date","tags","category"}, new int[] { R.id.comment, R.id.amount,R.id.date,R.id.tags_container,R.id.category } ); SimpleAdapter.ViewBinder binder = new SimpleAdapter.ViewBinder() { @Override public boolean setViewValue(View view, Object object, String value) { //Log.d(TAG,"view.toString()= "+ view.toString()); if (view.getId() == R.id.tags_container) { String[] tags = value.split(","); ((LinearLayout) view).removeAllViews(); for (String tag : tags) { View v = createTagView(activity.getLayoutInflater(),tag); ((LinearLayout) view).addView(v); } return true; } return false; } };

  • webBrower Button Click without element ID?

    - by Jeremy
    I'm working on a login system for a forum and trying to make it work via a c# .net form. I need to programitically click the login button on the forum with a webBrower control. So far I have this. webPage page = new webPage(); page.URL = txtURL.Text; page.Load(); //Load the text from the specified URL WebBrowser browser = new WebBrowser(); browser.Document.GetElementById("navbar_username").SetAttribute("value", textBox1.Text); browser.Document.GetElementById("navbar_password").SetAttribute("value", textBox2.Text); HtmlElement el = browser.Document.All["btnI"]; if (el != null) { el.InvokeMember("click"); } else { MessageBox.Show("There is an issue with the program"); } The issue is that the login button on the page does not have an ID or any real information that can allow me to click on it. Does anyone have any suggestions? Here is the code for the login button. <input type="image" src="images/loginbutton.png" class="loginbutton" tabindex="104" value="Log in" title="Enter your username and password in the boxes provided to login, or click the 'register' button to create a profile for yourself." accesskey="s">

  • Ant path/pathelement not expanding properties correctly

    - by Jonas Byström
    My property gwt.sdk expands just fine everywhere else, but not inside a path/pathelement: <target name="setup.gwtenv"> <property environment="env"/> <condition property="gwt.sdk" value="${env.GWT_SDK}"> <isset property="env.GWT_SDK" /> </condition> <property name="gwt.sdk" value="/usr/local/gwt" /> <!-- Default value. --> </target> <path id="project.class.path"> <pathelement location="${gwt.sdk}/gwt-user.jar"/> </path> <target name="libs" depends="setup.gwtenv" description="Copy libs to WEB-INF/lib"> </target> <target name="javac" depends="libs" description="Compile java source"> <javac srcdir="src" includes="**" encoding="utf-8" destdir="war/WEB-INF/classes" source="1.5" target="1.5" nowarn="true" debug="true" debuglevel="lines,vars,source"> <classpath refid="project.class.path"/> </javac> </target> For instance, placing an echo of ${gwt.sdk} just above works, but not inside "project.class.path". Is it a bug, or do I have to do something that I'm not? Edit: I tried moving the property out from target setup.gwtenv into "global space", that helped circumvent the problem.

  • Input questions mysql php html

    - by Marcelo
    (Q1)Hi I'm using textbox in my project and I can't receive the values that are typed <textarea rows="5" cols="60"> Type your suggestion </textarea> <br> <input type="submit" name="sugestao" value="Submit" /> Sorry I don't know how to 'kill' html code, that's why < is missing. All I'm getting in the column of the database from this text box is "Submit", I'd like to receive whatever is written in the text area. How can I make the value equal whaterever is typed? (Q2) How can I make sure that I'll only store the same type(int,varchar,text) that I setted,declared in the database. For example: age(int), but if someone types "abc" in the input it will be stored in my database as the value 0 . How can I forbid this, and only save the age when it's just int and all the other fields(like name, email) are filled ?. And if is still possible warn the user that he is typing something wrong, don't need to say where. Sorry for any mistake in English and Thanks for the attention.

For Ex:http://localhost:1985/Materials/Details/4 But it shows error, The model item passed into the dictionary is of type 'System.Data.Linq.DataQuery`1[CrMVC.Models.ConstructionRepository+Materials]' but this dictionary requires a model item of type 'CrMVC.Models.ConstructionRepository+Materials'.

  • autocomplete: how do I avoid a duplicate search?

    - by dnagirl
    I use JQuery plugin autocomplete as a kind of dataset chooser. If the user chooses a value from the autocomplete lookup, the database is queried for the matching dataset. If the user types in a new value, the user can enter a new dataset. An issue arises when the user types in an existing value rather than choosing it from the autocomplete lookup. When this is done, the autocomplete .result() method is not called and no dataset is retrieved. To fix this I added a .blur(function(){$(this).search();}); to the input element. This fixed the original problem. Now I have the problem that .result() fires on selection from lookup AND on blur. I would like .result() to fire on selection from lookup OR on blur. How do I make that happen? Here is my code: $('#groupset').autocomplete('ajax/php/leeruns.php'); $('#groupset').result( function(event, data, formatted) { if(data){ $('#groupsetdesc').val(formatted); groups.load(data[1]); //retrieve matching dataset } else { $('#groupsetdesc').val(''); } } ).blur(function(){$(this).search();});

  • List modification in Python

    - by user2945143
    We are given an algorithm to modify a list of numbers from 1 to 28. There are 5 steps in the algorithm. We have written functions for each step (all correct). We need to write a function that combines all 5 steps. The algorithm modifies the list to get a value. Each time you get a new value, you use the list created by the algorithm from the previous step. This is what we have gotten so far for the code: get_card_at_top_index(insert_top_to_bottom(triple_cut((move_joker_2( move_joker_1(deck)))))) When we run the code to generate the get_card_at_top_index, the first answer is correct. However, the rest are not. Instead of using from the new list, python uses the value that it generated from the last step. What did we do wrong? UPDATE: The other 5 codes passed the tests, they are correct. Code 1 (List) = list1 Code 2 (list1) = list2 Code 3 (list2) = list3 Code 4 (list3) = list4 Code 5 (list4) = list5 we generate a number from 5. We need to run the algorithm again to generate 25 more numbers. We will use list 5 start from step 1

  • Casting Type array to Generic array?

    - by George R
    The short version of the question - why can't I do this? I'm restricted to .NET 3.5. T[] genericArray; // Obviously T should be float! genericArray = new T[3]{ 1.0f, 2.0f, 0.0f }; // Can't do this either, why the hell not genericArray = new float[3]{ 1.0f, 2.0f, 0.0f }; Longer version - I'm working with the Unity engine here, although that's not important. What is - I'm trying to throw conversion between its fixed Vector2 (2 floats) and Vector3 (3 floats) and my generic Vector< class. I can't cast types directly to a generic array. using UnityEngine; public struct Vector { private readonly T[] _axes; #region Constructors public Vector(int axisCount) { this._axes = new T[axisCount]; } public Vector(T x, T y) { this._axes = new T[2] { x, y }; } public Vector(T x, T y, T z) { this._axes = new T[3]{x, y, z}; } public Vector(Vector2 vector2) { // This doesn't work this._axes = new T[2] { vector2.x, vector2.y }; } public Vector(Vector3 vector3) { // Nor does this this._axes = new T[3] { vector3.x, vector3.y, vector3.z }; } #endregion #region Properties public T this[int i] { get { return _axes[i]; } set { _axes[i] = value; } } public T X { get { return _axes[0];} set { _axes[0] = value; } } public T Y { get { return _axes[1]; } set { _axes[1] = value; } } public T Z { get { return this._axes.Length (Vector2 vector2) { Vector vector = new Vector(vector2); return vector; } public static explicit operator Vector(Vector3 vector3) { Vector vector = new Vector(vector3); return vector; } #endregion }

  • I need Selenium to open it's web browser in a larger resolution ( preferably maximized)

    - by user1854271
    I am using Selenium WebDriver and coding in Python I have looked all over the place and the best I could find were things written in different languages. I also tried to use the export tool on Selenium IDE but when I look at the data says that the function is not supported for export. EDIT: The reason I need the browser to open up with a larger resolution is because the web application that I am testing is supporting tablet resolution as so elements are different depending on the resolution of the browser window. This is the script I exported from the IDE with a couple of modifications. from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import Select from selenium.common.exceptions import NoSuchElementException import unittest, time, re from Funk_Lib import RS class CreatingEditingDeletingVault(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.implicitly_wait(30) self.base_url = "http://cimdev-qa40/" self.verificationErrors = [] def test_creating_editing_deleting_vault(self): driver = self.driver driver.get(self.base_url + "/Login?contoller=Home") driver.find_element_by_id("UserName").click() driver.find_element_by_id("UserName").clear() driver.find_element_by_id("UserName").send_keys("[email protected]") driver.find_element_by_name("Password").click() driver.find_element_by_name("Password").clear() driver.find_element_by_name("Password").send_keys("Codigo#123") driver.find_element_by_id("fat-btn").click() driver.get(self.base_url + "/Content/Vaults/") driver.find_element_by_link_text("Content").click() driver.find_element_by_link_text("Vaults").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("New vault").click() driver.find_element_by_name("Name").clear() driver.find_element_by_name("Name").send_keys("Test Vault") driver.find_element_by_xpath("//button[@onclick=\"vault_action('createvault', null, $('#CreateVault [name=\\'Name\\']').val())\"]").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("Rename vault").click() driver.find_element_by_name("Id").click() Select(driver.find_element_by_name("Id")).select_by_visible_text("Test Vault") driver.find_element_by_css_selector("option[value=\"2\"]").click() driver.find_element_by_name("Name").clear() driver.find_element_by_name("Name").send_keys("Test Change") driver.find_element_by_xpath("//button[@onclick=\"vault_action('renamevault', $('#RenameVault [name=\\'Id\\']').val(), $('#RenameVault [name=\\'Name\\']').val())\"]").click() driver.find_element_by_css_selector("button.btn.dropdown-toggle").click() driver.find_element_by_link_text("Delete vault").click() driver.find_element_by_name("Id").click() Select(driver.find_element_by_name("Id")).select_by_visible_text("Test Change") driver.find_element_by_css_selector("option[value=\"2\"]").click() driver.find_element_by_xpath("//button[@onclick=\"vault_action('deletevault', $('#DeleteVault [name=\\'Id\\']').val(), '')\"]").click() def is_element_present(self, how, what): try: self.driver.find_element(by=how, value=what) except NoSuchElementException, e: return False return True def tearDown(self): self.driver.quit() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main()

  • AJAX filter MySQL results using checkboxes

    - by keepitnang
    I'm attempting to get to grips with displaying filterable MySQL data within a PHP page based on user checkbox selections. I have a database of domain names and the dates on which these will require renewal as per Nominet DAC information and I can get unfiltered data to display, but filtering results by domain extensions is proving tricky for me to accomplish. I should point out at this stage that I am a serious newcomer to many of the ideas I am trying to learn to work with here, so please be gentle. I have tried following some other articles on here also, but no dice. I have the following so far: HTML <input type="checkbox" class="extensions" name="extensions" value=".co.uk">.co.uk</input> <input type="checkbox" class="extensions" name="extensions" value=".org.uk">.org.uk</input> Script $('.extensions').live('click', function() { var all_boxes = $('.extensions'); var all_boxes_values = []; var i = 0; for (var i; i < all_boxes.length; i++) { if (all_boxes[i].checked) { all_boxes_values.push(all_boxes[i].value) } } var all_boxes_values_clean = all_boxes_values.join(", "); console.log(all_boxes_values_clean); $.get("sql-test.php", {q: all_boxes_values_clean}, function(result) { $("div#output").html(result); } )}); PHP $g = $_GET['q']; $extensionsql=""; $extension=1; if(isset($g)) { $extension=1; $param = "" . str_replace(",", "','", $_GET['q']) . ""; } And that's as far as I have gotten with my limited ability. What I would like to do next is search the column domainName for a string match and return the appropriate results to the user. Something to mimic something like the following but I'm not sure how to achieve it. Any help would be much appreciated: SELECT * FROM `refresh` WHERE `domainName` LIKE '%.co.uk%' AND renewalDate LIKE '%2012-06-30%' ORDER BY `domainName` ASC Thanks

  • C# function called after dependency property have been set

    - by mizipzor
    My code currently looks like this: private Foo myFoo; public Foo CurrentFoo { get { return myFoo; } set { SetFoo(value); } } private void SetFoo(Foo newFoo) { // Do stuff // Here be dragons myFoo = newFoo; } To be able to bind it in XAML/WPF I need to turn Foo into a dependency property: public static DependencyProperty CurrentFooProperty = DependencyProperty.Register("CurrentFoo", typeof(Foo), typeof(FooHandler), new PropertyMetadata(false)); public Foo CurrentFoo { get { return (Foo)GetValue(CurrentFooProperty); } set { SetValue(CurrentFooProperty, value); } } Ive heard that you shouldnt do magic inside the actual C# property set {}, since it might not be called but the value is written directly to the dependency property. If this is false, let me know, it seems like the most obvious and simple route to take. I know I can add a validation function to the dependency property but I assume that it shouldnt be used for this? I need to communicate the change to legacy systems that cannot yet be bound in XAML. Whats the best way to approach this problem?

  • .Net Inherited Control Property Default

    - by Yisman
    Hello fellows Im trying to make a simple "ButtonPlus" control. the main idea is to inherit from the button control and add some default property values (such as font,color,padding...) No matter how i try, the WinForm always generates (or "serializes") the property value in the client forms the whole point is to have minimal and clean code, not that every instance of the buttonPlus should have 5 lines of init code. I want that the form designer should not generate any code for theses properties and be able to control them from the ButtonPlus code. In other words, if I change the ForeColor from red to blue only 1 single bingle line of code in the app should change. heres my code so far. as you can see, ive tried using defaultvalue, reset , shouldserialize.... anything i was able to find on the web! Public Class ButtonPlus Inherits Button Sub New() 'AutoSize = True AutoSizeMode = Windows.Forms.AutoSizeMode.GrowAndShrink Font = New System.Drawing.Font("Arial", 11.0!, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, CType(177, Byte)) Padding = New System.Windows.Forms.Padding(3) Anchor = AnchorStyles.Left + AnchorStyles.Right + AnchorStyles.Top ForeColor = Color.Aqua End Sub ' _ 'Public Overrides Property AutoSize() As Boolean ' Get ' Return MyBase.AutoSize ' End Get ' Set(ByVal value As Boolean) ' MyBase.AutoSize = value ' End Set 'End Property Public Function ShouldSerializeAutoSize() As Boolean Return False ' Not AutoSize = True End Function Public Function ShouldSerializeForeColor() As Boolean Return False 'Not ForeColor = Color.Aqua End Function Public Overrides Sub ResetForeColor() ForeColor = Color.Aqua End Sub End Class Thank you very much for taking the time to look this over and answer all the best

  • ResXResourceWriter Chops off end of file

    - by Aaron Salazar
    I'm trying to create a .resx file from a dictionary of strings. Luckily the .Net framework has a ResXResourceWriter class. The only problem is that when I create the file using the code below, the last few lines of my generated resx file are missing. I checked my Dictionary and it contains all the string pairs that I expect. public void ExportToResx(Dictionary<string,string> resourceDictionary, string fileName) { var writer = new ResXResourceWriter(fileName); foreach (var resource in resourceDictionary) { writer.AddResource(resource.Key, resource.Value); } } Unfortunately, it is a little difficult to show the entire resx file since it has 2198 (should have 2222) lines but here is the last little bit: ... 2195 <data name="LangAlign_ReportIssue" xml:space="preserve"> 2196 <value>Report an Issue</value> 2197 </data> 2198 <data name="LangAlign_Return BTW, notice that the file cuts off right at the end of that "n" in "LangAlign_Return". The string should read "LangAlign_ReturnToWorkspace". The file should also end at line 2222.

    - by user1815871
    Powershell newbie ... I recently learned about splatting — very useful. I ran into a snag when I passed a hash table by reference to a function for splatting purposes. (For brevity's sake — a silly example.) Function AllMyChildren { param ( [ref]$ReferenceToHash } get-childitem @ReferenceToHash.Value # etc.etc. } $MyHash = @{ 'path' = '*' 'include' = '*.ps1' 'name' = $null } AllMyChildren ([ref]$MyHash) Result: an error ("Splatted variables cannot be used as part of a property or array expression. Assign the result of the expression to a temporary variable then splat the temporary variable instead."). Tried this afterward: $newVariable = $ReferenceToHash.Value get-childitem @NewVariable That did work and seemed right per the error message. But: is it the preferred syntax in a case like this? (An oh, look, it actually worked solution isn't always a best practice. My approach here strikes me as "Perl-minded" and perhaps in Powershell passing by value is better, though I don't yet know the syntax for it w.r.t. a hash table.)

  • Haskel dot (.) and dollar ($) composition: correct use.

    - by Robert Massaioli
    I have been reading Real World Haskell and I am nearing the end but a matter of style has been niggling at me to do with the (.) and ($) operators. When you write a function that is a composition of other functions you write it like: f = g . h But when you apply something to the end of those functions I write it like this: k = a $ b $ c $ value But the book would write it like this: k = a . b . c $ value Now to me they look functionally equivalent, they do the exact same thing in my eyes. However, the more I look, the more I see people writing their functions in the manner that the book does: compose with (.) first and then only at the end use ($) to append a value to evaluate the lot (nobody does it with many dollar compositions). Is there a reason for using the books way that is much better than using all ($) symbols? Or is there some best practice here that I am not getting? Or is it superfluous and I shouldn't be worrying about it at all? Thanks.

  • (Rails) Creating multi-dimensional hashes/arrays from a data set...?

    - by humble_coder
    Hi All, I'm having a bit of an issue wrapping my head around something. I'm currently using a hacked version of Gruff in order to accommodate "Scatter Plots". That said, the data is entered in the form of: g.data("Person1",[12,32,34,55,23],[323,43,23,43,22]) ...where the first item is the ENTITY, the second item is X-COORDs, and the third item is Y-COORDs. I currently have a recordset of items from a table with the columns: POINT, VALUE, TIMESTAMP. Due to the "complex" calculations involved I must grab everything using a single query or risk way too much DB activity. That said, I have a list of items for which I need to dynamically collect all data from the recordset into a hash (or array of arrays) for the creation of the data items. I was thinking something like the following: @h={} e = Events.find_by_sql(my_query) e.each do |event| @h["#{event.Point}"][x] = event.timestamp @h["#{event.Point}"][y] = event.value end Obviously that's not the correct syntax, but that's where my brain is going. Could someone clean this up for me or suggest a more appropriate mechanism by which to accomplish this? Basically the main goal is to keep data for each pointname grouped (but remember the recordset has them all). Much appreciated. EDIT 1 g = Gruff::Scatter.new("600x350") g.title = self.name e = Event.find_by_sql(@sql) h ={} e.each do |event| h[event.Point.to_s] ||= {} h[event.Point.to_s].merge!({event.Timestamp.to_i,event.Value}) end h.each do |p| logger.info p[1].values.inspect g.data(p[0],p[1].keys,p[1].values) end g.write(@chart_file)

  • How to face observable object containing an observable field

    - by iseek
    Hello, I need a hint concerning MVC and Observer-Pattern. For example a model contains the classes "Address" and "Person". The Address class contains the fields street:String, zipcode:String, location:String. Whereas the Person class contains the fields name:String, firstName:String, address:Address. My approach so far looks something like this: Both, Address and Person are observable. If one of their setters is being called, I validate whether the current value and new value differ. Only in this case an update event is fired. The event contains the source, the name of the changed field, the old and the new value. The class for the view contains text fields to display and edit the information of a person: name, firstname, street, zipcode, location. It knows the Person model and is an subscribed observer for the person. So it gets the update events from the person object. My questions concerns the address field from type Address in the person class, since an address is observable on its own. If the view gets an update event from person when a new address has been set, I can update all of the address related fields in the view. But what if a field of the address changes? Should the view also register for update events from the address? Any hints about common design approaches would be appreciated. Greetings.
