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.

Error when installing a Custom Component

Hi there,
I wrote a custom component and built the according jar-file. The next step was to import the jar-file into the workbench.
When I tried to do so the following error occurred (workbench .log file):
!ENTRY com.adobe.DSC_Admin_UI 4 4 2008-01-15 16:05:43.418
!MESSAGE install of C:\tmp\adobe-components\adobe-component.jar failed
!STACK 0

Caused by: java.io.FileNotFoundException: C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\ArchiveStore\306\at\integrata\livecycle\component\Boot strapImpl.class (The system cannot find the path specified)
The problem is, that the workbench is not running on the same computer as the ES server. When I extract the jar-file manually into the considered directory on the server everything works fine.
Is this a bug or even not possible to import components from a remote workbench?
kind regards
Michael

Hy all,
I have been having the same problem.
I think the cause with me is that I added libraries my component needs manually into the jar-file of my component and sometimes I added the component.xml file manually into the component-jar. I use 7Zip for this but every I did that I could not get the component to install correctly, unless I unpacked it manually in the temp-dir.
I believe this is happens because when I manually place files in the jar file with a tool like 7Zip they are automatically being compressed and the jar-file of a component must not be compressed.
So therefore I imported everything correctly in my Eclipse-project and now when I Export my component to a jar-file, everything is included and I don't have to place files manually into the jar-file of my component.
When I install a component created like that I don't have any problems.
Hope this helps for you to.
Regards,
RonnyR

Error when calling a custom component in Web UI.

Hello Experts ,
We have created a custom component for guided procedure in Web UI . When we link the custome component with the standard component for the home page ( WCC_SSV_HOME ) we found that custom controller for guided procedure works . We are navigating the guided procedure for search functioanlity and it works fine and shows the search result .
But when we click on any of the searched objects say a Case , then links on that Case is not working .
For example , we are getting the below error :
Exception Class CX_BSP_WD_INCORRECT_IMPLEMENT - Define NavigationalLink BP for source view ZSOA.MainWindow
Any inputs on this is higly apreciated.
Regards
Vinayak

Hi Vinayak,
I am assuming that the implementation of the navigation from the search result to the object details is not working.
The error you mentioned pointed me that you do not have the navigation link. I don't know what is missing so I am giving you the full details please cross check what you missed.
1> create and eventhandler e.g. EH_ONSINGLESELECTION
2> create an outbound plug in your view - this plug is used for the navigation to the target of the hyperlink.
3> create an outbound plug in the window.
Define the navigation link whth the name according to the string you have put in the event handler in the search component e.g. SINGLESELECTION
as source define the component usage for the search. as target define the component usage of header -> this will handle the connection from search to the header.
Hope this will help.
Thanks,
Vikash.

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
Yog

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}" />

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

*** 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 can i solve this problem? thanks

Hi Rui
Very difficult to know from your description.
It's a class-cast exception - try to find the line in your code that's doing the cast, and find out what the actual object is.
It could also be a jar versioning problem, or a class-loader problem.
Sorry, very difficult to help without doing some detailed debugging.

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;

Error when calling bpm service from custom component

Hi all,
I have built a custom component in order to fetch task related data by calling a bpm service inside the method of my custom service.
This is the error trace i got in audit info.
"not loading page MSG_PAGE because it is up to date with timestamp 1324331008000

What does this error signify?
In the service definition of my custom service, I am using MSG_PAGE as my template. Is it related to this why i am facing the error? how do i get to know for a particular functionality i should use a particular template?
Please provide your inputs asap.
Thanks in advance.

HI jiri,
Please have a look at the stacktrace and provide me a solution as in how to overcome the error.
I had included Report.trace in order to check the flow of the program and found that the problem arises when i establish the connection.
