Hi,
I found something surprising, while working on a Tomahawk application, in
which I added Trinidad for a couple of components.
Trinidad overrides default renderers of some javax.faces.* components like
Form, HtmlCommandButton and HtmlCommandLink.
Why is this needed?
I noticed it adds some custom scripts.
BUT why should it be so intrusive in the default renderers?
The problem that made me find this was that I got some exceptions in the
tomahawk PPR.
Except on some pages, the only Trinidad component I use is tr:document to
have the skinning enabled.
I definitely expect for the Tomahawk PPR within a h:form and containing an
h:commandButton to work.
i got this stack trace on a PPR submit:
