Intellij IDEA reports “Cannot resolve symbol” in .tml files

Question

Here's a problem. Intellij IDEA constantly shows "Cannot resolve symbol" errors while I'm working on a project which includes Tapestry framework. This error appears only in *.tml files. Another thing I've noticed is this error pops up very selectively. For example, IDEA recognizes <t:if> tag, but cannot parse <p:else> . I've already tried to reimport maven dependencies, invalidate cache and import the whole project again.

Answer 1

It seems that this is a bug in Tapestry 5 IDEA Plugin. Unfortunately, there is no workaround at this moment (see Issue C for details).
