[stringtemplate-interest] unexpected char error in using "AND" or "OR" operators in templates

[Joe Tam]

Hi,

I'm trying to use the OR operator in a string template and ran into the
error below. I am using the antlr-3.4-complete.jar.

My template looks something like this:

$if(descriptor.condition1 || descriptor.condition2)$

generatedString

$endif$


Can't parse chunk: if(descriptor.hasPackage || descriptor.syncUIEnabled)

line 1:26: unexpected char: '|'

Does anyone have a clue how to fix this error?

Thanks,
