dynamic form generation, seam, conversations

[thetom]

Hi!

I am doing dynamic form generation with jboss, jsf and seam.
But I have problems with conversations when trying to use them with the dynamic forms. It seems that I am loosing the conversation context.

So, I have two buttons.
ButtonA calls a method, annotated with @Begin from a statefull session bean.
ButtonB calls another method, annotated with @End from the same bean.

If I put these two buttons in a .xhtml file (commandButton) the long running conversation works, and the method annotated with @Remove and @Destroy is called when I press ButtonA and then ButtonB.

But when I am generating these buttons programmatically, the long running conversation doesn't behave as it should.

Any hints where I should start to debug this behaviour?

The "static" buttons are done in this way:

 <h:commandButton id="doB" value="doB"
 action="#{x.doB()}"/>

And here one of the dynamic buttons:

HtmlCommandButton cancelButton = new HtmlCommandButton();
 cancelButton.setId("doB");
 cancelButton.setValue("doB");

 // create method binding
 FacesContext context = FacesContext.getCurrentInstance();
 Application app = context.getApplication();
 MethodBinding mb = app.createMethodBinding("#{x.doB}", new Class[] {});
 cancelButton.setAction(mb);

 sheet.getChildren().add(cancelButton);

thx in advance,
tom

How does it not work?

Hi!

The conversation seems to be ignored. No bean properties are saved between the two button-clicks, and the @Destroy and @Remove method isnt called after invoking the @End-annotated method via the programmatic button.

I think you'll have to get your debugger out, sorry.

i am not sure what exactly the point was, but now it works.
