Is there a Role object asserted into your working memory?<br><br> Remember that adding the Role pattern to your rule will make your rule fire once for each Role object. If you don't have any role object, the rule obviously will not fire.

developers,</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;"> </span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">In our specific use case we have customers who need to be able to write validation rules and NOT have to resort to writing them in Java. Hence our interest in using drools as an open source 'standard' to potentially replace a proprietary rules engine we already have.
</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;"> </span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">In the previous case I mentioned where I want to do this:
</span></font></div><span><div><font face="Courier New" size="2"><span style="font-size: 10pt;"> </span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> *rule* "UCCnet_DVE_Depth_All"
</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> *when*</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> catalogObject : CatalogObject( )
</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> String s = catalogObject.getElementValue("depth");</span></font></div><div><font face="Courier New" size="2">
<span style="font-size: 10pt;"> > *eval*( s == *null* || s == "" )</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> *then*</span></font></div><div><font face="Courier New" size="2">
<span style="font-size: 10pt;"> > logWriter.logDebug("Package
Depth is Blank");</span></font></div></span><div><font face="Courier New" size="2"><span style="font-size: 10pt;">> *end*</span></font></div><div><font face="Courier New" size="2"> <span style="font-size: 10pt;">
</span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">This is because potentially, in our use for data validation, there might be 50 values we need to compare against. Those values need to be on the drools (not java) side of the world. So getting the result of
catalogObject.getElementValue("depth") into a String variable and being able to use String methods like indexOf or multiple || cases is much more desirable than crossing from the rule back into the object by having to call getElementValue 50 times. There are numerous, other cases, where the result of
catalogObject.getElementValue need to be saved into a local drools variable and evaluated multiple times without encurring the overhead of multiple
calls back into java.</span></font></div><div><font face="Courier New" size="2"> <span style="font-size: 10pt;"> </span></font></div><div><font face="Courier New" size="2"><span style="font-size: 10pt;">Please consider enhancing drl syntax to support this use case. Is there a bug/enhancement process for me to follow to submit this functionality request.
