<br> try using double \ inside evals and consequences... not sure if it will work, but try it out... this should all be fixed in drools 5.<br><br><div class="gmail_quote">2008/8/27 samlotti <span dir="ltr"><<a href="mailto:samlotti@gmail.com">samlotti@gmail.com</a>></span><br>

Hello,<br>
<br>
I'm trying to construct a rule in drool V4 that contains and eval and a<br>
literal string that may contain quotes. I've tried escaping the quote but<br>
get the error below. The \" works outside an eval.<br>
<br>
rule "evalList2"<br>
when<br>
Var( eval( "tt".equals("t\"t")))<br>
then<br>
System.out.println( "evalList2" );<br>
end<br>
<br>
<br>
Error:<br>
java.lang.NullPointerException:<br>
at<br>
org.drools.rule.PredicateConstraint.createContextEntry(PredicateConstraint.java:201)<br>
at org.drools.reteoo.AlphaNode.createMemory(AlphaNode.java:230)<br>
...<br>
<br>
It looks like a change was made to V3 to fix this but doesnt appear to work<br>
in V4, does anyone know how to construct this type of rule?<br>
<br>
Thanks<br>
Sam<br>
