[rules-users] Can eval($param) be used as condition in the Spreadsheet decision table?

[Wishing Carebear]

Is it possible to put eval($param) as Condition in the decision table so
that the cells can have flexible values.?

Thanks.

If you mean in Guvnor, then no you cannot define a predicate not associated
with a pattern I.e. only Pattern( evaluate( something) ) is possible at
present. The same question was asked yesterday too so please file a JIRA and
we can look into implementing as it appears to be needed.

If you mean in XLS decision tables then I believe this is possible now.

Use of Templates in Guvnor might be an option for you that supports
predicates not associated with a pattern now by using free form DRL.

Yes, all the decision table compiler does is convert the cells into a drl file 
by doing some string manipulation, all it does with $param is do a string 
replace, so if you end up with a valid statement after the replacement has been 
done you can do whatever you like. Similar as you are suggesting some of our 
rules are constructed like field $param 0 where the cell values are either ==, 
= etc.
