Call back bean method from a facelet template.

[Jakim Rachev]

Hi,

I've looked every where for that, and I just can't find a solution. I have a composition element which I want to include in various facelet pages, every each with a unique backBean but sharing same interface. So is there any way to pass only the backBean instance to this composition element from the client pages. I tried this method:

Composition Element comEl.xhtml

<ui:composition>
    <s:link action="#{bean.sayHello}" disabled="#{bean.getCount()==0}" />
</ui:composition>

Client page page1.xhtml backBean=page1Bean

<ui:include src="/layout/comEl.xhtml">
    <ui:param name="bean" value="#{page1Bean}" />
</ui:include>

Actually disabled="#{bean.getCount()==0}" works ok, if the count is 0 the link gets disabled.
But action="#{bean.sayHello}" doesn't work.

Exception during request processing:
Caused by javax.el.PropertyNotFoundException with message: "Target Unreachable, identifier 'bean' resolved to null"

I'm not sure what your problem is, unless there's something funny about the "s:link" element itself. I do this sort of thing extensively and other than my choice of elements in the included text, that's the way I do it.

Although a quick check indicates I'm using "ui:component", not "ui:composition". I can't remember the difference offhand, but I'm fairly sure that one of them limits the context that gets pulled in.

Yes it seems that the problem is in <s:link>. Just right now i tried with h:commandLink and everything was just fine.
Thanks Tim.
