Hi guys!

The problem I'll explain isn't a seam problem, but, perhaps, You can help me.

I'm very new to facelets. so, please excuse me if I weren't clear enought

I've an application, where I use some tomahawk components.

If i deploy my application in a Jboss for the first time, everything works perfectly. My problem is on a hot redeploy of my application. Then, I start to have this stacktrace

This is the problematic code

 <div class="input">
 <t:inputDate id="buyDate" value="#{placeEditor.entity.buyDate}" popupCalendar="true"/>
 <br/><span class="errors"><h:message for="buyDate"/></span>
 </div>

I must say that if I cut the popupCalendar attribute, everything works ok. I can reproduce the same behaviour with all my tomahawk components (I use PanelNavigator2 and others)

After making some research on the list, I've found this https://facelets.dev.java.net/servlets/ReadMsg?listName=users&msgNo=2179

There Jacob promise to make a change in MetaTagHandler, but I've seen that this code is untouched for 11 month!!!

I think it's a classpath problem, but Actually I don't know how to solve it.

After writing in to the facelets list, I've received this message form Jacob

I need to chat with the JBoss guys, because the MetaTagHandler does:

if (mapper == null || !localType.equals(instanceType)) {
// rebuild meta data
}

but if you are changing the type, then I wonder why the localType is equal to the instanceType.

And this is true! Between deploy and deploy, the instanceType is the same that the type cached!! And even worse, When I call the method by reflection it fails??

Anyone has faced it? Is there a workaround??

Thanks!
