Re: Custom tag
Hi
You can try the alternate syntax using "targets". For example:
Instead use EL, you can use the id hierarchy to locate the component.
In this case, there will not be NullPointerException, because only if
the property is set, the value is assigned. I have tested both syntax
in MyFaces with tons of tests:
http://svn.apache.org/repos/asf/myfaces/core/trunk/impl/src/test/resources/org/apache/myfaces/view/facelets/tag/composite/
and it works without problem.

Message order in h:messages does not match component order
Hi, with template: messages in h:messages does not match order of components, h:messages will show: 2: Validation error 3: Validation error 1: Validation error It looks like that problem occurs where h:messages is wrapped in another component, this works: but this doesn't: With Mojarra h:messages or PrimeFaces p:messages message order does match component order. Should I file this as bug? Regards, Pavel
