All,
Many thanks. Changing $item.Folder_code from a byte to an int wasn't a good
option, as it is part of a core data class. The easiest fix (once I
realized the cause of the problem) was to make the following changes:
-in the Java module, add this line: context.put("byte", new
Byte((byte)0));
-in the template, change previous line to this:
#if($byte.toString($item.Folder_code) == "0")
BTW, I'm *very* impressed with Velocity. I'm converting an entire
Enhydra-based application to it as we speak (well over 100 'pages'). Since
I'm still in a 'beginner's mind" mode (read, Velocity newbie), here are a
couple of observations so far in terms of formal user/developer
documentation suggestions:
1. make it more clear that string varbs are concatenated without '+' between
terms and *must* be enclosed in quotes.
2. explain how $formatter works
3. explain how to make comparisons with non-integer values
I'm learning that Velocity is *incredibly* powerful and flexible, but I also
find I have to dig around a lot to find how to use some of these
capabilities. I'd be glad to help someone insert these suggested wording
additions (and others I find) into the docs if desired.
Best regards,
Terry
