tr:form defaultCommand won't work with empty value
--------------------------------------------------
Key: TRINIDAD-1355
URL: https://issues.apache.org/jira/browse/TRINIDAD-1355
Project: MyFaces Trinidad
Issue Type: Bug
Components: Facelets
Reporter: Caius Gran
The problem is tr:form's defaultCommand attribute throws an exception if it's
left empty.
And this is a problem at least for my case where I try to make a Facelets
template with a parameterized
defaultCommand attribute. Whenever I was to use the template, I would have to
put something into
the defaultCommand parameter even if I didn't need defaultCommand for that
particular instance.
Basically I must give it a bogus value to make it work (see "this_is_bogus"
below).
I'd like to have it work without explicit ui:param.
I encountered it with Trinidad 1.0.8 and didn't try other versions.
Thanks!
