Description
I'm developing an application which uses more layers of <tiles:insert> than I
have often used in the past. It seems that when an error occurs during JSP
execution within an inserted tile, something causes the wrapping tiles to be
executed more than once.
Sometimes, this is just visually annoying, as it may make a navigation element
appear more than once when an error occurs; more recently, it has been more
deeply annoying, because the recursive execution was showing me an error which
was actually masking the true problem. It took me a long time to recognize this
and turn to solving the root problem.
One could probably test this just by writing some tile sets and using a
scriptlet to throw an exception from a nested JSP. If I have some time, i'll
try to do that, but right now I need to catch up for all the time lost by that
masked error.
I ascribe this problem to Tiles because when I changed one tiles:insert into a
jsp:include, I saw one less level of nesting.
Also of potential import: at least once while I was digging around, I seemed to
get this nesting behavior in the absence of an exception – but at that point I
was too frustrated to really be able to isolate the issue and the variables.
