com.sun.faces.facelets.tag.jsf.core.PhaseListenerHandler$LazyPhaseListener

[Volodymyr Levytskyi]

Hello!

Whereever I put my tag <f:phaseListener type="com.olympics.util.MessagePanelListener" /> I always receive this error in server.log:

[#|2012-09-29T21:41:50.187+0200|SEVERE|glassfish3.1.2|javax.faces|_ThreadID=137;_ThreadName=Thread-2;|Exception invoking UIViewRoot PhaseListener com.sun.faces.facelets.tag.jsf.core.PhaseListenerHandler$LazyPhaseListener.|#]

The interesting thing that my phase listener com.olympics.util.MessagePanelListener is invoked and it outputs some info untill line :

 UIPanel msgPanel = (UIPanel) root.findComponent("j_id1" + UINamingContainer.getSeparatorChar(context) + "j_idt9");

There parent id is - j_id1 and searched component's id is - j_idt9!

Can anybody tell me how to resolve this?

Thank you!

Two things will help.

1. Explicitly assign "id=" attributes to the XML elements of interest. That will make it easier to tell which ones are offending, since the generated IDs are unpredictable.

2. Provide a complete stack trace. All we can tell from your present example is that it failed. Not where or why.

Thank you for response!!!

I have already left the idea to use <f:phaseListener . By the way error in server.log was only one line which I provided.
Instead I decided to create my own jsf component as it serves better here. My goal is to create message panel which displays all messages queued on FacesContext.
Example: 'You are logged in successfully'. Problem - deferred value expression doesn't work. Code in my tag-class method setProperties(UIComponent component):

 UIMyMessage uimm = (UIMyMessage) component;
.........
if (title != null) {
            if (!title.isLiteralText()) {
                uimm.setValueExpression("title", title);
            } else {
                uimm.getAttributes().put("title", title.getExpressionString());
            }
        }
...........

This sets value expression 'title' into my component 'UIMyMessage'.
Code that should write evaluated value expression into 'title' attribute

if (getValueExpression("title") != null) {
            writer.writeAttribute("title", getValueExpression("title"), null);
        } else if (getAttributes().get("title") != null) {
            writer.writeAttribute("title", getAttributes().get("title"), null);
        }

As a result title on my component is - /template.xhtml @87,90 title="#{bundle.Template_messagePanel}. It means that deferred expr. is not evaluated.
After I tried to change line 02 to:

writer.writeAttribute("title", getValueExpression("title").getValue(elContext), null);

It gave the following stack trace:

'This panel is to notify user about something' is bundle's title which I want to see as title.

Don't you know what it is wrong here?

[Volodymyr Levytskyi]

I had custom component that extends UIOutput without custom renderer. Its attribute 'title' had to be evaluated to String from bundle via deferred value expression. In custom component I had property String title with normal getter and setter. Then I simply removed them and put this code:

public String getTitle() {
    return (String) getStateHelper().eval("title");
}

public void setTitle(String title) {
    getStateHelper().put("title", title);
}

To write evaluated title into my component:

if (getTitle() != null) {
            //method getTitle() gives me evaluated already expression 
            writer.writeAttribute("title", getTitle(), null);
}
