The RHS of a rule X winds up in some class Rule_X_0. Calls like insert(), retract(), etc. are, by definition, method calls of WorlingMemoryEntryPoint, and the compiler ought to prefix them with the global reference to that object, i.e., "drools". This fails within if statements, both branches.

If you write, inside (or outside) if
   drools.insert(...);
   drools.retract(...)
all is well.

   This is odd, since this part of the code didn't changed much from drools 4 to 5 (assuming you are using java dialect for your consequence). Can you open a JIRA with your test case plz?

Hi,

This rule (not the best style) compiles fine in 4.07. It gives this error
message using 5.0 Snapshot. I changed some of the text to be generic so I could
post the code.

Rule Compilation error : [Rule name='A.B.inlet.mxb.first.link.20090216.01']
       com/zzzzzz/yyy/awl/Rule_A_B_inlet_mxb_first_link_20090216_01_0.java
(11:5517) : The method insert(RuleLink) is undefined for the type
Rule_A_B_inlet_mxb_first_link_20090216_01_0


Here is the rule: (I had to change all the > to . to get gmane to accept the
email as a non top post)

rule "A.B.inlet.mxb.first.link.20090216.01"
agenda-group "A.B"
when

.     comp :     XComponentRule( path == "~unit~mxb")
then
.     Point3d l = new Point3d();
.     comp.getBounds().getLower(l);

.     if (l.x < 1)  {
.        insert( new RuleLink("FIRST.INLET" , comp, comp) );
.     } else {
.        insert( new RuleLink("FIRST.INLET.NOT" , comp, comp) );
.     }
.
end

If I change the rule to

rule "A.B.inlet.mxb.first.link.20090216.01"
agenda-group "A.B"
when

.     comp :     XComponentRule( path == "~unit~mxb")
then
.     Point3d l = new Point3d();
.     comp.getBounds().getLower(l);
.     String name = "FIRST.INLET";
.     if (l.x < 1)  {
.       // nothing
.     } else {
.       name = "FIRST.INLET.NOT";
.     }
.     insert( new RuleLink(name , comp, comp) );
.
end

it compiles w/o a problem.
