I actually got the same idea, just after pushing the send button. It's
quite a task, though, to carve this out. But it's certainly my job.
I'll make a try.
In the meanwhile: an observation. Looking at the breakpoint in
BugPage.getListsource () I can see the call stack. At the top is
Layout._$read_parameter_listSource() line: not available
InternalComponentResourcesImpl.readParameter(String, String) line: 248
InternalComponentResourcesImpl.readParameter(String, Class<T>) line: 233
To my understanding, this means that for some reason is indeed the
listSource parameters coerced to a String; this is what
readParameter(String, String) as all about?!
Stay tuned, I'll come be back w something compilable. Thanks for your time!

Hey Alec,
I was hoping for something a little more minimal, but still
complete/compilable. :)
I still can't reproduce the problem, but maybe @Persist on your report
property is the culprit? Try it with out that. That's a shot in the
dark though, so if that doesn't help I think I'll need something
broken that I can actually run through a debugger to go any deeper.

Hey Alec,
Looking at small excerpts from a large file leaves too much to the
imagination. Can you create a minimal but complete page and component
that reproduces the problem?
Yes, I should have done it long time ago, I know. Below is the complete
example, removing all old stuff trailing around. Here comes:
- What's rendered (ascii)
- BugPage{.tml|.java}
- Layout{.tml,|java}
- ReportSize{.tml,.java}
As you can see, the ReportSize component works whereas the Layout doesn't.
For the moment, I presume that the situation still is such that the problem
is about the listSource parameter, while the columns is fine.
Debugger says same thing: the value returned from BugPage.getListsource() is
a List<IRow> w 500 items. The value stored as @Parameter listSource in
Layout is a SingletonList containing the serialized value of the 500 item
list. This is returned by getListSource() in Layout as-is.
Note that I've cut away lot's of stuff from BugPage. Layout.java is as-is
(for now).
