Custom Component Classes

Hi all
I have been learning flex for a few months now and absolutely
loving it!
But there is one thing I can't get my head round. I use to be
a Flash user mostly which is probably why I am getting confused....
I want to be able to make custom components that all use one
custom class.
For example, I have custom canvas components that are 'pages'
which I am loading dynamically as and when needed. When they load I
want them to fade in using the fade effect. Up until now I have
written the code to do this on each component, which is quite
annoying considering I have many pages.
I would like a custom class with the code in it for the fade
which every 'page' component uses, so each will fade in when
loaded.
I could this really easily using MovieClips in flash, but
flex seems different. Maybe I am getting confused with regards
Canvases and MovieClips.
Please can someone help me? :)

Why not just define the effect in the main file and then
apply it from the
outside, rather than locking your component into one effect:
<yourNameSpace:YourCanvas width="200" height="200"
creationCompleteEffect="{someEffectYouMade}" />

Error "expected a myfaces custom component class in package"

Can anybody help me on this?
just copied the sandbox code on selectmanypicklist and tried in a separate package of mine.
created a jsp page and used the selectmanypicklist component and im getting the component on my browser.
But whn i added the javascript resource calling by "encodeJavascript(facesContext, uiComponent);" im geting an error saying tht "expected a myfaces custom component class in package org.apache.myfaces.custom". i placed the java script file in "mypackage/list/resource/pikscript.js".
should i add anything on faces-config.xml file or anywhr else?
Anybody can help on this?
Thanx in Advance.

The problem is that it calls a method validateCustomComponent in MyFacesResourceHandler to see if it can load the js file. This method controlls if the path of the js file begins with org.apache.myfaces.custom. If not throws an exception and doesn't load the file. I changed the package of the class that's trying to load the file in org.apache.myfaces.custom.xx and the package of the file js in org.apache.myfaces.custom.xx.resource. Now it's working.

LCES server caches the custom component classes

I found that sometime during the (patching) deploy/undeploy install/uninstall phase of custom component LCES start 'caching the custom component or its helper classes' and any changes made to them does not get reflected.
But after the server restarted every thing work as expected.
i.e. If server is restarted the latest changes to component deployed previously to server restart get reflected.
Pl. help.
Any one had simillar issue?
Thanks
Yog

Hi Paul,
I have tried both of these frequently (many times)
1) Component > STOP > PATCH > START
2) Component > STOP > UNINSTALL > INSTALL > START
but no effect after some point when server keeps the cache. (it works some time but not all the time I thought 2nd approach should always work)
But if I restart the server it seems to show the expected result always.
Does any Adobe teche knows how to gaurrentee 100% that chnges will reflect after new version of the component is installed without restart of the server.
Also I seen some inside the service impl at the begining of the service method code store the classloader:
ClassLoader originalClassloader = Thread.currentThread().getContextClassLoader();
and restore it at the end of service method:
if (originalClassloader != null) {
Thread.currentThread().setContextClassLoader(originalClassloader);
How does this affect?
and also if one component depends on another how does that affect?
Thanks

Custom component class is not detecting url parameter

I have a hcsp page, on which i have a link something like this :
"<$HttpCgiPath$>?IdcService=CUSTOM_SERVICE&var1=value1"
m appending one more parameter in this url through java script.
so one is the var1 which is directly here in the url and one m appending through java script so my final url would be:
"<$HttpCgiPath$>?IdcService=CUSTOM_SERVICE&var1=value1&var2=value2"
M calling a java function which fetches these variable.
my code is
String value1=m_binder.getlocal("var1");
This is working fine .
But when i do it for var2, this gives an error " variable var2 is not found" in the logs.
Please guide
Thanks,
Chely

Thanks Jonathan. i have executed m_binder.toString() and in the logs:
m_binderString
*** LocalData ***
(9 keys + 0 defaults)
IdcService=SUNRISE_DEL_TAX_USER

var1=1
tax_type=N

*** RESULT SETS ***
var1 is here but var2 is not here in the result set, Now what should i do to make it available in my binder,because in my hcsp java script i have an alert of url and in this alert i am able to see the complete url including var1 and var2.
Thanks,

How to construct the component tree in my custom component?Help!

Hi, i am writing a custom component like this:
public class HtmlCategory extends HtmlPanelGrid
     public void processRestoreState(javax.faces.context.FacesContext context,
            java.lang.Object state)
          setColumns(1);
          HtmlCommandLink link=new HtmlCommandLink();
          link.setValue("Let's Bingo");
          MyUtil.setActionListener(context,link,"#{temp.mytest}");
          UIParameter param=new UIParameter();
          param.setName("name");
          param.setValue("Robin!");
          link.getChildren().add(param);
          param.setParent(link);
          getChildren().add(link);
          link.setParent(this);
          super.processRestoreState(context,state);
}         you see, i want to construct the compont tree at Restore View phase this way,because the structure of the component tree will always be the same, so i don't the user to write extra code.
But the children of the component are not rendered,the renderer of the HtmlCategory component just extends the HtmlGridRenderer(myfaces) directly,and always calls the "super" methods in the encode methods of the renderer.
I got a message from the console:
Wrong columns attribute for PanelGrid id0:id4: -2147483648
but i have set the columns attribute in the code above, so what's happening? or please give some advice about how to render the component tree by myself in Restore View with the tree constructing code in the custom component class code,just lke the code above.
Best Regards:)
Robin

Well, i don't know if i have got my question clear.
usually, according to the tags you use in the jsf page, a component tree will be created at the Restore View phase,for example:
<f:form>
<h:panelGrid ...........>
          <h:dataTable ................>
          </h:dataTable>
   </h:panelGrid>
</f:form>but because i am writing a component for my web app, all the child components and their attributes are not likely to change. so i want to reduce the tags into one custom tag, and construct the component tree internally by myself.But it is not the case of backing bean.So i wrote the the code in the method:
public void processRestoreState(javax.faces.context.FacesContext context,java.lang.Object state)as it is shown in my orginal message.But it seems that it is not right way to construct my component tree.So where should i put the code that construct the component tree?Overriding the method :
public void processRestoreState(javax.faces.context.FacesContext context,java.lang.Object state)is not the right way?
Best Regards:)

JPanel won't display my custome component

Hi,
I made a custome component class that in its paint method at this stage is suppose to paint a white rectangle on screen. However the when I add this custome component to my JPanel it doesn't show up. Does anybody have a solution for this?
My code for the custome component is,
public spaceMediaDisplayObject(mediaObject mo){
     x = mo.getSpaceX();
     y = mo.getSpaceY();
     height = mo.getHeight();
     width = mo.getWidth();
     name = mo.getName();
     System.out.println("Constructor");
     this.repaint();
public void paint(Graphics g){
     System.out.println("Draw");
     g.setColor(Color.white);
     g.drawRect(x, y, height, width);
And the fragment of code I am using to try and display in on the panel is as follows,
spaceMediaDisplayObject smdo = new spaceMediaDisplayObject(toDisplay);
     spaceBodyPanel.add(smdo);
Please help if able.

If it's null then you need to set the size of each component explicitly:
JPanel panel = new JPanel(null);
Component customComponent = new CustomComponent();
panel.add(customComponent);
customComponent.setBounds(0, 0, 100, 100); // For exampleA simple layout manager could be used to make the component fill the panel, for example:
JPanel panel = new JPanel(new GridLayout(1, 1));
panel.add(new CustomComponent());Hope this helps.

PPR on custom component

I have a custom component for calendar. When invoking PPR on the component it refreshes the entire contents of the page and the custom component doesn't work properly after that.
If I manually do full a page refresh then the component works properly.
There is a thread with a similar problem was resolved Re: PPR on custom component?
In above thread the solution was to add below in the custom component class.
@Override
protected FacesBean.Type getBeanType()
return TYPE;
I do have this code in my custom component class but may be I am missing something else. Does anyone have a suggestion of how to make this work? I'd appreciate your help a lot.

Yes, I've seen that page on Trinidad. It was helpful, but it seems it was mostly about using PPR, not about building it into a custom component. The one part that did talk about custom components was this, near the end:
"Finally, if you're implementing a custom component, you aren't extending the Trinidad UIXComponentBase base class or one of its subclasses, and you want to support partialTriggers, you'll need to use addPartialTriggerListeners(). If you deliver events, and you want to support being the target of partialTriggers, you'll need to use partialUpdateNotify(). "
Then it gives code snippets for each of those. In my case, I am extending UIXComponentBase, and I am including this code, and I know addPartialTriggerListeners gets called, but my component still doesn't get the updated data. If I right-click the page and select Refresh, it redraws correctly, and other components that have partial-triggers on the same component I do, do get the update properly. So I must be missing something.
Also, where can I get the open source of the components from? I haven't found anywhere to download them from. Can you point me at them?

How do I tie a custom-component to a class?

In flash there's this great way of seperating code from
content: In the properties menu of a movieclip in your library, you
can assign a class name to the movie. So something I very regularly
do is:
class MyMovieClip extends MovieClip{
//etc..
so I'd have all the code that manages my movies nicely tucked
away in some .as files, no code in the fla. That's the way I like
it.
So I was wondering if you can do a similar thing in Flex. I
most definitely don't want the code for my application in the .mxml
file, I actually want to inherit the Application class. Similarly,
I'd like to inherit the Canvas class, yet have the nice gui for
dragging all the visuall elements in place. Is there a way?
Regard, and thanks in advance,
Karel

If you look in the library panel, there should be an entry for your custom component - probably something like CustomComponent1.mxml. Drag this out onto the artboard to create a new instance of the component.
In the case of a custom component, you can't change much on the second instance. If you have something like a text input skin though, you can change the text it is displaying for each instance.
We are working on making this sort of thing easier in the future, so stay tuned

How to use a flex custom component in an AS3 Class?

Our software team has been developing flash applications using AS3 (via the FlashDevelop IDE and the free Flex SDK). Recently, some members of the team started exploring FlexBuilder and Flex (wow... why did we wait so long?). The problem is that some folks continue to develop using pure Action Script 3 (FlashDevelop) while others are creating custom components in FlexBuilder.
How do the AS3 developers use the Flex Custom components built in FlexBuilder in their AS3 Applications?

SwapnilVJ,
Your suggestions enabled me to make progress, but I'm still having a problem. Based on you suggestion, I learned how to make a swc using Flex Builder. I successfully added the swc to the lib resource in my AS3 project (FlashDevelop). I was able to instantiate one of my new components (code hinting even picked it up from the lib).
When I run my app, my component is not visible. I can trace properties of it and the values are correct. Any thought why I might not be seeing my custom component?
package trainer.games.board.MatchThree {
import flash.display.Sprite;
public class Test extends Sprite{
private var cp:MatchingGameControlPanel; // <<< this is my swc custom component created in Flex
public function Test() {
   cp = new MatchingGameControlPanel();
   cp.visible = true;
   addChild(cp);
   trace("width: ",cp.width); // <<< works and displays valid data for the component.

Custom component/tag class: ---which setters/getters do what?

Hi
I'm trying to create a custom component, but, there is a major concept that I do not understand...
---What are the setters/getters in the "component" class used for?...
---What are the setters/getters in the "tag" class used for?
Another way of asking is...
---Which setters/getters are used simply to keep track of attribute name/id/key?
---Which setters and getters refer to the actual objects that the attribute names point to?
The reason for my confusion is that nearly all "custom component" examples I've seen thus far, utilize attributes that point to "String" objects... (i.e., as opposed to ArrayList, HashMap, etc)...
This makes it difficult for me to distinguish whether the String values in the getters/setters are referring to the String name/"id" of the attribute...or, the String "value" of the attribute...
I have not been able to verify how I should code the getter/setters (and type casts) for other kinds of objects like ArrayLists, HashMaps, etc
For example, a typical logic mechanism Ive seen in the custom "tag" examples is as follows...
in a "tag" class...
        if( tabledata != null )
            if (isValueReference (tabledata))
                FacesContext context = FacesContext.getCurrentInstance ();
                Application app = context.getApplication ();
                ValueBinding vb = app.createValueBinding (tabledata);
                component.setValueBinding ("tabledata", vb);
            else
                component.getAttributes ().put ("tabledata", tabledata);
in the "component" class...
    public void setTabledata (List tabledata)
        this.tabledata = tabledata;
    public List getTabledata ()
        if(null != tabledata)
            return tabledata;
        ValueBinding _vb = getValueBinding ("tabledata");
        if(_vb != null)
            return (List)_vb.getValue (getFacesContext ());
        else
            return null;
    }...considering the above code,
---when/where should the "tabledata" variable be referring the "name/id" of the attribute?...
---when/where should the "tabledata" variable be referring to the "value" of the attribute?...
...as, I need to change the type casting to adjust to what it should be...
***NOTE: This is one error that I'm getting, and I believe it is because I do not understand how getter/setter is used in "component" and "tag" classe, i.e., :
"org.apache.jasper.JasperException: jsp.error.beans.property.conversion
     org.apache.jasper.runtime.JspRuntimeLibrary.getValueFromPropertyEditorManager(JspRuntimeLibrary.java:885)"...
Thanks for any help on this!
sd

The "tabledata" variable always refers the local value of the attribute.
When using a value binding to some backing bean,
the local value is null and the model value is owned by the bean.
You don't need any casting in the tag class nor the component class.
The setters/getters in the component class specify the type of the attributes.
Conversion from/to String to/from the type is done automatically if possible.
When the automatic conversion is impossible, you should specify f:converter
for the attribute.

Jars in the class path of a custom component

I am using the dom4j-1.6.1.jar library in a custom component, but my JBoss server has dom4j.jar in jboss\server\all\lib. My custom component is throwing the following error:
DefFoundError message:org/dom4j/xpath/DefaultXPath while invoking service XmlToCsvService and operation convert and no fault routes were found to be configured.
This makes me suspect that the version of Dom4J in the lib directory of the server is taking precedence over the one in my component. Any suggestions for how to deal with this? Thanks.
Jared Langdon

Even Marcel's suggestion may not always work, but it certainly is worth a quick try. I seem to remember trying that and finding that one of the LiveCycle EAR files has a version of dom4j buried inside it (I don't remember which version of LC it was).
Of course altering an Adobe supplied EAR is not recommended and may violate your support ageement. There is an alternative, however; if changing the JBoss lib folder doesn't work. To avoid the conflict you can use JarJar to rename the packages within the DOM4J class and deploy the renamed jar with your component to avoid the conflict.
http://code.google.com/p/jarjar/
You would then use the renamed classes in your component:
import org.mypackage.dom4j.Document;
import org.mypackage.dom4j.DocumentException;
import org.mypackage.dom4j.DocumentHelper;
import org.mypackage.dom4j.Element;
import org.mypackage.dom4j.Node;
import org.mypackage.dom4j.io.DOMReader;
import org.mypackage.dom4j.io.DOMWriter;

Building custom Component -- choice of base class...

Hello,
I am building a customer component. The component will be a AJAX enable Grid.
I am not sure what base class would be the best.
I am planning on using the "UIComponentTag" as the base class of my tag file. Here is the declaration:
public class EbaAjaxGridTag extends UIComponentTag {
Let me know how-you all feel about this choice.
Cheers,
Godfrey

Yep, that's the right class. All JSF component tags inherit UIComponentTag (eventually in their hierarchy). I suppose there is UIComponentBodyTag, but you should make a custom renderer instead of writing the tag body from the tag class. In other words, you don't want UIComponentBodyTag.
It would also be ok if you wanted to extend another component tag (i.e. InputTextTag). This would give you access to the pre-existing attributes of that tag class. HOWEVER, you should be warned that these tag classes can change in future versions of JSF. So make sure you are willing to maintain it in the future before doing that.

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";
public class UIRptTableData extends HtmlDataTable {
     public UIRptTableData() {
          setRendererType("tblmaint.rptTableDataRenderer");
     public String getFamily() {

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">
<f:facet name="header">
<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>
<h:selectBooleanCheckbox
id="checked"
binding="#{RepeaterBean.checked}"/>
<%-- Invisible checkbox for "created" flag --%>

You may have a look at HTML source to prove that dataTable is already what you need:
<table id="myform:table">
<thead>
<tr><th colspan="6" scope="colgroup">Customer List</th></tr>
<tr>
<th scope="col"></th>
<th scope="col">Account Id</th>
<th scope="col">Customer Name</th>
<th scope="col">Symbol</th>
<th scope="col">Total Sales</th>
<th scope="col">Commands</th>
</tr>
</thead>
<tbody>
2.) The second trouble is still unsettled as previously. Right now I have different task at my job, and I can�t continue investigation of this problem.
But when you find smth., please let me know. I�ll be very grateful.

How do you reference a valueObject located in main to a custom component created in Catalyst?

Hello,
I have been working with the Catalyst Beta 2 / Flash Builder beta trying to create a photogallery and have hit a little bit of a snag, try as I might I can't seem to find the answer anywhere. I am still new to Flex so please excuse me if this is a basic question, I have been trying to understand more about Flex to make my designs in Catalyst better.
I found this video on Adobe TV: http://tv.adobe.com/watch/rich-internet-applications-101/ria-stepbystep-16-binding-a-data- service-to-flash-builder-components/
It's wonderful and I have the datalist I created in Catalyst working with the XML file I generated but I designed my little photogallery a bit diffrent, I created a Custom Component in Catalyst so that when you click an item on the DataList it pop's up a little screen with a larger photo in on it, rather then having an image in the main application. Now my problem seems to be that I can't refrence the valueObject I created with the wizard as it's in my Main.mxml file, is there a way to refrence it from my Custom Component so the larger image will display? Is there a way to let the component know which item on the dataList in the main application is selected and display the correct image?
I should also say I really enjoy working with the Beta for both Flash Builder / Catalyst, thanks for the hard work!
Thanks for the help,
Chris

I am afraid you cannot bind to static properties in Windows Store Apps. It is simply not supported.
You could create a proxy class that exposes the static command property and bind to this property of an instance of the proxy object:

http://stackoverflow.com/questions/4708711/how-can-i-use-the-xstatic-extension-for-phone7-silverlight-apps
You will of course have to create an instance of the proxy object. There is no way around this.

Problem with attributes in custom component

Hi All,
I am creating a simple jsf PanelGrid custom component....in that component I am adding two new attributes....
when I use that tag in my jsf application it is rendering fine in the client side....but the parent class that is PanelGrid component's attributes are not inheriting to my custom panelgrid....
can any one tell me how can I use the attributes of the super class PanelGrid??
Thanks...

Have you configured the attributes in the tag library descriptor?
