Okay, digging more into the source code I found the method “replaceOptionals” which does exactly what I need. So despite the missing docs, a line IS skipped if the according parameter used in that line is null. Perfect :-)

Sorry for the interruption…

Betreff: [rules-users] Rule Templates and null values

Hi all.

I question myself if I can get the Rule Templates to works like it is in Excel: If one “parameter” is not set (null), the whole line of the template is skipped?

Since we want to build a template for a lot of rules, fed from a database. There some conditions can be null, so they should not be included in the rule at all. Has anybody an idea to this? I haven’t found anything, neither in the docs, nor in the testcases…

Thanks a lot

Bernd
