Re: [rules-users] DrlParser not supporting temporal operators

Thanks Edson. That worked. But the problem is that if i am using a temporal operator condition as: *this before[5s, 0s] $res* the equivalent XML generated is as follows: *<field-constraint field-name="this"> <variable-restriction evaluator="before" identifier="$res" /> </field-constraint>* over here *[5s,0s]* information is getting lost in the transformation. Is there any fix for this? Cheers, Swapnil 2009/11/21 Edson Tirelli <ed.tirelli(a)gmail.com&gt; > All operators in drools are pluggable.
