[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 havent found anything, neither in the docs, nor in the testcases Thanks a lot Bernd ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Rule Templates and null values
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 Von: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] Im Auftrag von Bernd Rücker Gesendet: Freitag, 26.

Enlighten us. Where is this method and how to use it? I'm also interested.

Re: [rules-users] Rule Templates and null values
It works out of the box. So in this example:
12 rule Cheese fa...@{row.rownumber}
13 when
14Person(age == @{age})
15Cheese(type == @{type})
16 then
17list.add(@{log});
18 end
If you provide age=null, line 14 is not included in the rule
automatically.

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 havent found anything,
neither
in the docs, nor in the testcases
Thanks a lot
