I am developing a Seam web application with 2.0.0.GA and I am writing a custom
facelets component that instantiates seam and a4j components and renders
itself.
Everything seems to be working fine but I have a problem where
HtmlAjaxCommandLink (and HtmlCommandLink) will not work to call an action
method I have set using setActionExpression, though switch to HtmlLink and it
works fine.
| HtmlAjaxCommandLink link = new HtmlAjaxCommandLink();
| link.setId("link-"+id);
| div.getChildren().add(link);
| link.setParent(div);
| link.setValue(name);
| link.setReRender("some-id");
| MethodExpression methodExpression
FacesContext.getCurrentInstance().getApplication().getExpressionFactory().createMethodExpression(FacesContext.getCurrentInstance().getELContext(),
"#{SomeAction.editAction("+id+")}", null, new Class<?>[0]);
| link.setActionExpression(methodExpression);
|
When I click this link it seems to rerender the part of the page it's supposed
to, however the action is not called. This happens similarly when the link is
defined as HtmlCommandLink except the page is reloaded.
When I define the link as HtmlLink (seam link) it works fine and the action is
called, but the page is reloaded, and I am trying to do it with an ajax
rerender.
One hint is about my problem is that when the a4j;outputPanel that I am
rerendering is not set and ajaxRendered=false than the link doesn't rerender
anything and a4j log output is as follows:

But when I change the a4j outputPanel to ajaxRendered=true the link seems to
work (besides calling the action) and the panel does get rerendered and the a4j
log looks normal and contains the xhtml for the panel that is to be rerendered.
Anything obviously wrong with what I am doing? Any hints are appreciated.
Thanks,
Jon
