Hibernate: Parent/Child relationship in a single-table

- by Dee

I hardly see any pointer on the following problem related to Hibernate. This pertains to implementing inheritance using a single database table with a parent-child relationship to itself. For example: CREATE TABLE Employee ( empId BIGINT NOT NULL AUTO_INCREMENT, empName VARCHAR(100) NOT NULL, managerId BIGINT, CONSTRAINT pk_employee PRIMARY KEY (empId) ) Here, the managerId column may be null, or may point to another row of the Employee table. Business rule requires the Employee to know about all his reportees and for him to know about his/her manager. The business rules also allow rows to have null managerId (the CEO of the organisation doesn't have a manager). How do we map this relationship in Hibernate, standard many-to-one relationship doesn't work here? Example code would be appreciated.

iPhone sdk, at dismissModalViewcontrollerAnimated, the parent change y origin coordinate

- by DigitalVanilla

Hi guys, my first post here :) I'm having a small trouble with a small but boring problem. I have a view, with a NavigationController. I load in the NC a simple view. Inside this view there's abutton where I fire the presentModalView... in the main view, not on NC, but it's parent view: ABVIEW NC NEWVIEW new attach a presentModalView... on ABVIEW, so [abview present...]; No problem till now. When it's the time to dismiss, after the temporary window (let's calls it NOTES) disappear, my ABVIEW with all the subviews change Y position from 0 to 20, the same height of the status bar. I was looking everywhere and I'm sure it's a stupid thing, but I miss a bit of knowledge here and I have no idea where to find the solution. thanks in advance!

iPhone UITableView trigger a parent method?

- by MidnightLightning

Okay, so I'm working on an iPhone app with a preferences-esque section where there's a base TableView, which has one section, and several rows of customized cells to hold a name and a value label. Clicking on a row brings up another View, which allows the user to pick from a list (another TableView), and select an item. All of these TableViews are done programatically. The base TableView has a property that holds a Controller instance for each of the "pick from the list" Views. Each of the "pick from the list" views has a property called chosenValue that has the currently-selected option. I've gotten the UI to handle the didSelectRowAtIndexPath to update the chosenValue property and then "pop" the view (going back to the main TableView). But, even though the main TableView's cellForRowAtIndexPath method references the chosenValue property of the subview that's held in a property, the view doesn't update when an item is selected. In short, how can the sub-view trigger a reloadData on the parent object, after it "pops" and unloads?

AS3: Accessing variable declared on MovieClip's parent

- by Joel Alejandro

I have a frame which contains an mcMenubar MovieClip. On the frame, I have this code: import Nem.* import fl.transitions.Tween; import fl.transitions.easing.*; import fl.motion.Color; var pageLoader:SwfLoader = new SwfLoader(root, 199, 144); On the mcMenubar clip, I want to access that same pageLoader instance: var pageFile:String = "page-" + e.target.name.replace(/btn/gi, "").toLowerCase() + ".swf"; this.parent.loadPage("loadertest.swf"); // THIS WON'T WORK // var tweenMove:Tween = new Tween(gfxSelected, "x", Bounce.easeOut, gfxSelected.x, e.target.x, 1, true); currentlySelected = e.target.name; Apparently I'm getting this error: TypeError: Error #1010: A term is undefined and has no properties. at MethodInfo-71() How can I fix this?

AnkhSVN: No Versioned Parent Directories when adding a Web Site

- by CJM

I've recently been trying out Ankhsvn and I quite like it, and more importantly, it generally likes me. But I've hit a problem adding existing VS projects to subversion using AnkhSVN. Most Windows and Web projects are added fine, but I have a problem when I try to a Websites (as opposed to Web Applications), and in these cases I get the following error: No versioned parent directories After some googling, I've come across other people with the same problems and there have been one or two suggests for solving the problem, but non so far have worked. AnkhSVN is popular enough, and although web applications are often preferred to websites these days, I'm hoping that someone here has a ready solution available.

Grouping Windows Forms Radiobuttons with different parent controls in C#

- by Jerry

Hi, I've got a Windows Forms application in which I have a number of RadioButtons. These RadioButtons are placed within a FlowLayoutPanel which automatically arranges them for me. All RadioButtons that are directly added to the FlowLayoutPanel are grouped, meaning I can select only one of them. However, some of these RadioButtons are paired up with a TextBox so I can supply some argument there. But to have all this arranged properly, I add a Panel control to the FlowLayoutPanel so I can control the alignment of the RadioButton and TextBox relatively to each other myself. These RadioButtons now have their own respective Panels as parent controls and thus are no longer included in the radio group with the other RadioButtons. I read that the the RadioButtons that are in the System.Web.UI namespace have a GroupName property, but unfortunately their System.Windows.Forms counterparts lack this property. Is there some other way I can group these radio buttons are am I going to have to handle onClick events myself? Thanks, Jerry

C# Initialize Subclass based on Parent object

- by ctrlShiftBryan

So basically I have this public class Ticket{ public TicketNumber {get; set;} ..a bunch more properties... } I want to add some properties using a subclass like this using subsumption instead of composition. public class TicketViewModel(Ticket ticket){ //set each property from value of Ticket passed in this.TicketNumber = ticket.TicketNumber; ...a bunch more lines of code.. //additional VM properties public SelectList TicketTypes {get; private set;} } How do I instantiate the properties without having to write all the lines like this this.TicketNumber = ticket.TicketNumber; Is there some kind of shortcut? Something like in the subclass constructor? this = ticket; Obviously this doesn't work but is their some way so I don't have to modify my subclass if addng/removing a property to the parent class? Or something?

Flash AS3 - Dispatching Events from Parent Class to Child Class

- by John Russell

I think this is a pretty simply problem but I do not seem to be able to pull it off. Basically I have a parent class A, and a child class B. Class A instantiates class B with addChild. There is a shared object which is being updated from a java server (red5) that has an event listener attached to it in class A. I have a function in class A which will pass certain, specific updates from this shared object to class B. The problem occurs is that when class B is instantiated, the event listener from class A doesn't work anymore. I have not removed the event listener from A. Any thoughts?

Zend Dd Rowset getting parent row

- by simple

I am wondering about using the abstraction in Zend Db RowSet instead of joins, is it possible for instance I am able to get some info from parent table as in here /** * Get default photo info (path , description) */ public function getDefaultPhotoInfo($userdId){ $select = $this->select($this) ->where('id=?', $userdId); $rowset = $this->fetchAll($select); $current = $rowset->current(); $res = $current->findParentRow('UserPhotos', 'Avatar'); if(isset($res)){ return $res->toArray(); } } How can I use Rowset abstraction to get this logic working table( id, pic_path,) table_translation(id, table_id, lang_id, pic_title); the above is representation of two tables , the idea is to get the info from both table specifying the lang_id , it is easy with joins but can I do it with the abstraction of Db Rowset ?

Owner Vs PArent and Taction shortcuts on Frames

- by Fred

I have a form with a panel. I create frames at runtime and display them on the panel by setting frame's parent property to the panel. When creating panels I do not set the owner property because i manage myself the lifetime of the frame. Until now i got no problem. Next I put an TActionList on the frame with some shortcuts on the actions. I found that my actions did not execute until I set the owner property of the frame to the panel. Can someone can explain me that ? I thought that owner property was just about wich component is responsible to free the children components, and not responsible to forward key events.

Accessing functions in a parent controller

- by meridimus

I have made a ViewController in XCode for an iPhone project I'm working on, but I have a question about nested ViewControllers and what the best way to access a parents ViewController functions? Essentially, at the moment I have a SwitchViewController with MenuViewController (nested) and GameViewController (nested, which renders OpenGL ES). At the moment, I have animated view switching controlled in the SwitchViewController which works. But I want to call it after a player has selected the level from the MenuViewController and run the appropriate level in GameViewController. Not rocket science, I know. What's the best way to call parent functions?

How to create 3 equally wide TextView which fill parent across the screen

HI, Can you please tell me how can I create 3 equally wide TextView which fill parent across the screen? I tried doing this, but the width of the TextView are different: it is 149, 89, 89. <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:stretchColumns="*" android:shrinkColumns="*"> <TextView android:id="@+id/t1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="0"/> <TextView android:id="@+id/t2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="1"/> <TextView android:id="@+id/t3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="2"/>

iPhone - Make loadView entries fill up parent view?

- by Eli

I have a loadView call that basically places one view at the top (like a header) and one at the bottom (like a footer). It's possible via a passed in parameter to not have a header or a footer, to hide them later, or to resize the view. I have all this working, but it's very susceptible to breaking because the views can go in various places of various sizes and all must be manually set to the correct size or they will not use up all the space. I want one in between the two of them that automatically resizes to fill whatever space is not taken by the others. loadView doesn't seem to be able to obtain the size of its parent's frame (or where it's being fit in, exactly), nor do I see an obvious way to just put the center view at a certain position and have its width and height automatically adapted. Any ideas? If I'm not explaining myself well enough and you know Java Swing, think BorderLayout with a BorderLayout.NORTH, BorderLayout.SOUTH, and BorderLayout.CENTER component.

Getting an icon to always be unrotated regardless of parent rotations in WPF

- by Jeff Moser

Is there an easy way in WPF to specify the orientation of an icon (or Button, or any WPF object) so that it always effectively remains unrotated regardless of the rotations of the parent transforms? For example, I'd like to have an icon like this: + + + + + +++++ + + + + + + + However, if I dock it to the left side, it'd by default look like this: +++++ + + + +++++ +++ + and if I docked it to the right, it'd be like this: + +++ +++++ + + + +++++ Is there a way to make it always be: + + + + + +++++ + + + + + + + ? I know I could manually track where it's docked and rotate it appropriately, but I was wondering if there's a clever way to effectively give the icon "gravity" to always point down. Thanks!

DB2 Child Table - Auto Delete With Parent

- by gamerzfuse

I have a bit of a task before me. (DB2 Database) I need to create a table that will be a child table (is that what it is called in SQL?) I need it so that it has a foreign key constraint with my other table, so when the parent table is modified (record deleted) the child table also loses that record. Once I have the table, I also need to populate it with the data from the other table (if there is an easy way to UPDATE this). If you could point me in the right direction, this would help alot, as I do not even know what syntax to look for. Thanks in advance
