[rules-users] "or" not working

[Yu Wang]

This doesn't work.  :(

Acutally I am using the eclipse plugin and the DSL viewer shows that
the source code looks fine. The code I put in my first email was taken
from the DSL viewer.

but when I add the three lines:
[condition][](=(
[condition][])=)
[condition][]or=or

The DSL viewer refuses to work and shows the following msg:
DSL Rule Translation Error!
Reason:
java.util.regex.PatternSyntaxException: Unclosed group near index 13
(\W|^)((\W|$)

I think it means "(" in the last word.
I also tried "("="(", and '(', didn't work either.
So I can't add the three mappings this way. Any ideas? Thanks!
