[rules-users] DrlParser not supporting temporal operators

[Swapnil Raverkar]

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
