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 @(protected) from a statefull session bean.
ButtonB calls another method, annotated with @(protected) 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 @(protected) and @(protected) 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
