Spring 3.2.4 + Tiles 3 = infinite loop when resolving view?

Question

I'm trying to use Spring MVC 3.2.4 & Tiles 3.0.1 with Regexp prefixes in my tiles.xml file. I'm a newbie with Tiles, so I might be doing something wrong, but have been trying to follow things I have read on in the Tiles doc site as well as apply stuff from the tech.finn.no blog.

Unfortunately, when I use completeAutoLoad=true with RegExp prefix in my tiles.xml file, I get stuck in an infinite loop when trying to resolve the view.

I don't think there is anything specifically special in this configuration, so am not sure why I get into an infinite loop. If I replace the CompleteAutoTilesInitializer class with the BasicTilesInitializerClass and use Wildcards (ie: /) instead and replace {1} with {1}/{2}, then the view loads properly (no infinite loop).

Any ideas what I am doing wrong, or is this a Tiles problem?

Answer 1

Found a similar SO issue (https://stackoverflow.com/a/6617343/827480) that pointed out that the regexp is too greedy and tries to match all attributes as well forever, hence causing the StackOverflow. Work around at the moment is to use a less greedy regexp.

Getting some traction under https://issues.apache.org/jira/browse/TILES-572 and http://thread.gmane.org/gmane.comp.apache.tiles.user/612
