Hi,
I have opened a thread with the same topic in the Wicket Users list, but
apparently this place is more suitable for this since we came to a
conclusion that the problem I'm facing cannot be solved without changing
some Wicket internals. Not to copy&paste here is the link to the thread on
Nabble:
http://www.nabble.com/Wicket-placeholder-for-%3Ctr%3E-component-causing-invalid-markup-td21663544.html
I think there would be a few ways to easily remedy the problem and the
easiest would be to allow to provide custom placeholder tags to be
provided. I would elaborate more on the different variants of the possible
solutions but I'd rather here what the core devs think about it. I
personally believe that supporting creation of validating markup should be
a priority of a web framework and here is a spot for small improvement.
