Hello Zied,
i hope the exception is fixed.
Look at https://issues.apache.org/jira/browse/TOBAGO-511.
Can you test next nightly build, please.
Regards

Hello Bernd,
I woke up thinking: it isn't possible!! I started my computer and this test
: :-)
In fact, I know that facelet's c:if is Tag (compile time tag), and that
<ui:out> is a Component (render time tag), and I already have (render
time)Components that work with the ui:include/ui:param which are (compile
time) Tags.
So I verified my example by trying to show the value of #{ajaxScope} in a
tc:out. And it shows!!! even if embedded inside a c:if tag (as was the case
with the tc:attribute). Then I added again the grey backgrounded code of the
attribute, and I received the NullPointerException, so I think it's a bug,
or there is a third phase type behind the compile and render phasis. (by
render I mean runtime)

Here's the exception. If you confirm it's a bug, let me know so i add an

Hello Bernd how are you?
Was I right when I said to Volker you're on holidays? If yes I hope it was
memorable.
I can't figure out what you meant by two commands, did you mean applying
the rendered attribute on the command instead of c:if and have two commands,
my c:if is only a workaround the NullPointerException I have mentioned
in the last mail?
to be more explicit : this is my case. The c:if can be removed, it is
there only in the case the attribute ajaxScope is not specified.

Hello Zied,
maybe two Commands with the rendered attribute would be a better choice.

Hi,
I have a little problem with runtime vs build-time tags:
I have a component page categories.xhtml containing the snippet:
<c:if test="#{not empty ajaxScope}">
<tc:attribute
name="renderedPartially"
value="#{ajaxScope}" />
</c:if>
included by a page as follows:
<ui:include
src="/contract/categories.xhtml">
<ui:param
name="ajaxScope"
value=":page:mainInfoTabPanel"
/>
</ui:include>
The c:if evaluates correctly at build time and adds the attribute to
its
parent. But it seems tc:attribute evaluates at runtime: it finds null.
Having two varibales one runtime and one build time with the same
value is a
little barbar.
Anyone knows how to resolve this? Any idea is welcome.
Regards,
Zied
