  • usage of setPropertyListener and setActionListener

    - by Vijay Mohan
    The incorrect usage could lead to hard-to-debug problems so better to understand the fundamentals behind it's working.setpropertyListener queues an event on the server side, so if for a command component you have a showPopup behavior/actionListner as well as setPropertyListener then fwk does the queuing correctly and raises further event on the component. While, the setactionListener simply raises an event on the server side instead of queueing it, so any further event on command component gets cancelled.Also, if you use an ActionListener and showPopup behavior together on a command component, then the order of their invocation is undetermined and also one of event gets cancelled on the component. So, either use only actionListner and do the popup invocation stuff progrmmatically in your bean or use the declarative stuff logically so that no clash of event happens.

  • Performance using T-SQL PIVOT vs SSIS PIVOT Transformation Component.

    - by Nev_Rahd
    Hi I am in process of building Dimension from EDW (source), wherein I need to pivot columns of source to load Dimension. Currently most of the pivoting stuff am doing is by using T-SQL PIVOT which further get used in my SSIS package to merge with Dim table This pivoting can also be achieved by SSIS PIVOT Transformation component. In regards to Performance which approach would be the best? Thanks

  • DoubleClick studio thinks I've imported the Enabler component in both my parent and my child asset f

    - by Marijn Huizendveld
    I've just started to work with DoubleClick Studio. I've successfully created a Flash expanding ad with CS4 that is mostly scripted and uses the Document class option. Now for some reason the back end of DoubleClick Studio thinks I've imported the Enabler component twice. I've checked my files numerous of times but can't find the root cause. Any help is much appreciated :)

  • Identifying Swing component at a particular screen coordinate? (And manually dispatching MouseEvents

    - by DVA
    I'm doing some work making a Java app compatible with alternative input devices. Unfortunately, the device in question has a Java API that's barely into the alpha stages right now, so it's pretty poor. What I need to do is essentially set up a replacement structure for the dispatch of MouseEvents. Does anyone know if there's a way in Swing to take a screen coordinate and find out what Swing component is displayed on top at that screen point?

  • Should I use Java for a custom Swing component designed for a clojure app?

    - by nansen
    I want a simple timeline component (like in video editing software) for a clojure/seesaw app and I am wondering if it is a good approach to implement this directly with clojure and seesaw or if I should write it in java and make my clojure wrapper around it. Or more generally: is a functional programming language optimal for writing UI widgets? I cannot imagine doing that without a lot of state involved. And wasn't OO invented for UI-development in the first place?

  • How to repeat a particular execution multiple times

    The following snippet generates create / drop sql for a particular database, whenever there is a modification to JPA entity classes. How do I perform something equivalent of a 'for' operation where-in the following code can be used to generate sql for all supported databases (e.g. H2, MySQL, Postgres) Currently I have to modify db.groupId, db.artifactId, db.driver.version everytime to generate the sql files <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>${hibernate3-maven-plugin.version}</version> <executions> <execution> <id>create schema</id> <phase>process-test-resources</phase> <goals> <goal>hbm2ddl</goal> </goals> <configuration> <componentProperties> <persistenceunit>${app.module}</persistenceunit> <drop>false</drop> <create>true</create> <outputfilename>${app.sql}-create.sql</outputfilename> </componentProperties> </configuration> </execution> <execution> <id>drop schema</id> <phase>process-test-resources</phase> <goals> <goal>hbm2ddl</goal> </goals> <configuration> <componentProperties> <persistenceunit>${app.module}</persistenceunit> <drop>true</drop> <create>false</create> <outputfilename>${app.sql}-drop.sql</outputfilename> </componentProperties> </configuration> </execution> </executions> <dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate-core.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j-api.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>${slf4j-nop.version}</version> </dependency> <dependency> <groupId>${db.groupId}</groupId> <artifactId>${db.artifactId}</artifactId> <version>${db.driver.version}</version> </dependency> </dependencies> <configuration> <components> <component> <name>hbm2cfgxml</name> <implementation>annotationconfiguration</implementation> </component> <component> <name>hbm2dao</name> <implementation>annotationconfiguration</implementation> </component> <component> <name>hbm2ddl</name> <implementation>jpaconfiguration</implementation> <outputDirectory>src/main/sql</outputDirectory> </component> <component> <name>hbm2doc</name> <implementation>annotationconfiguration</implementation> </component> <component> <name>hbm2hbmxml</name> <implementation>annotationconfiguration</implementation> </component> <component> <name>hbm2java</name> <implementation>annotationconfiguration</implementation> </component> <component> <name>hbm2template</name> <implementation>annotationconfiguration</implementation> </component> </components> </configuration> </plugin>

  • mig layout - span and grow/push problem

    - by pstanton
    i want 3 components laid out on 2 lines, so that the bottom component and the top-right component use all available horizontal space. JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.setLayout(new MigLayout("debug, fill")); Container cp = frame.getContentPane(); cp.add(new JTextField("component 1"), ""); cp.add(new JTextField("component 2"), "growx,push,wrap"); cp.add(new JTextField("component 3"), "span,growx,push"); frame.pack(); frame.setVisible(true); considering the above, how do i stop the space between "component 1" and "component 2" from appearing when resizing the frame? thanks.

  • UML binary association aggregatee has access to aggregator

    - by user314172
    Firstly, I'd like to thank those who answered my previous question ages ago. Currently I'm engaging more in the design phase UMLs, as this is my first medium scale deployment I'm entrusted with. This is extremely simple, but it bugs me so. If (Component) owns (Manager of Component), and (Manager of Component) has a reference to (Component) through which it manages it; how do you fully describe the relationship? I know it is aggregative, but how do you describe (Manager of Component) possessing a reference/pointer to the (Component) that physically owns the (Manager of Component) ? Example: Lidar owns a LidarManager

  • Jboss Seam: Enabling Debug page

    - by Markos Fragkakis
    Hi all, I want to enable the debug page. So, I have done the following: I have the jboss-seam and jboss-seam-debug jars as dependency in both my ejb and web maven projects (both are modules of my superproject) I put this context parameter in my web.xml: <context-param> <param-name>org.jboss.seam.core.init.debug</param-name> <param-value>true</param-value> </context-param> Now, when I hit the URL of my application, I get the debug page with this exception (full stacktrace at the end of the post): Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" From posts I read it seems that this is somehow related to two jars of jboss-seam or jboss-seam-debug being in the classpath. I opened my ear file and only one of each is present (in the ear) whereas the war itself has no libraries in the WEB-INF/lib. I have also read of another way to initialize debug page using the components.xml. I also tried to include the following components.xml in the WEB-INF, but it didn't work either: <?xml version="1.0" encoding="UTF-8"?> <components xmlns="http://jboss.com/products/seam/components" xmlns:core="http://jboss.com/products/seam/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.2.xsd http://jboss.com/products/seam/components http://jboss.com/products/seam/components-2.2.xsd"> <core:init debug="true"/> </components> Any suggestions on what to do to enable the debug page correctly? Cheers!

  • Can an interface be implemented across an aggregate/composite class in vb.net?

    - by Casey
    VB.NET .NET 3.5 I have an aggregate class called Package as part of a shipping system. Package contains another class, BoxType . BoxType contains information about the box used to ship the package, such as length, width, etc. of the Box. Package has a method called GetShippingRates. This method calls a separate helper class, ShipRater, and passes the Package itself as an argument. ShipRater examines the Package as well as the BoxType, and returns a list of possible shipping rates/methods. What I would like to do is construct an Interface, IRateable, that would be supplied to the helper class ShipRater. So instead of: Class ShipRater Sub New(SomePackage as Package) End Sub End Class we would do: Class ShipRater Sub New(SomePackage as IRateable) End Sub End Class However, ShipRater requires information from both the Package and its aggregate, BoxType. If I write an interface IRateable, then how can I use the BoxType properties to implement part of the Interface? Is this possible?

  • How do you composite an image onto another image with PIL in Python?

    - by Sebastian
    I need to take an image and place it onto a new, generated white background in order for it to be converted into a downloadable desktop wallpaper. So the process would go: 1) Generate new, all white image with 1440x900 dimensions 2) Place existing image on top, centered 3) Save as single image In PIL, I see the ImageDraw object, but nothing indicates it can draw existing image data onto another image. Suggestions or links anyone can recommend?

  • Can I get a person's display name or composite name from Apple AddressBook on OSX platform?

    - by AlexT
    I have come across ABRecordCopyCompositeName() in these pages but, having Spotlighted it, have a hunch it's only available for the IOS platform. The AddressBook app itself, and ABPeoplePicker obviously do something similar internally, so is there an equivalent API for OSX? It's a tedious thing to retrieve title, first name, middle name, last name, suffix and work out if it's a company before building it yourself.
