[rules-users] Template salience

[Enda J Diggins]

Hi,

Yes it is possible but I think the function has to return an int. Also, it
should be called as follows:

rule "Periode@{row.rowNumber}"
    salience ( getNbJours("@{ddeb}", "@{dfin}") );

Include the stack trace from the NPE if this doesn't work.
Cheers,
Enda
