Strange exception in other words say that it's not possible to find application template for some component. This problem shows just at production server not at my development machine. I'm using Tapestry 5 version 5.3.2.

After some time I found that problem was in directory naming. Templates in maven project are in directory 'src/main/webapps/buildinInstruction'. Name 'buildinInstruction' contains upper case I. When I change it to lower case problem disappears. Problem can't be reproduced at my machine because my Mac OS X use case insensitive file system.
