[rules-users] Guvnor errors stay forever

Hi all, Here's a funny thing I experience: I declare a function and do the mistake of verifying it before editing anything, while it's still a template (so it has chevrons). The verify obviously fails - but with a HTTP error 500! Server crashed?? Indeed I can see in the console: at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:951) [:6.0.0.Final] at java.lang.Thread.run(Thread.java:619) [:1.6.0_12] Caused by: java.lang.RuntimeException: Verifier Errors: [ERR 102] Line 1:9 mismatched input '<' in function [ERR 102] Line 1:36 mismatched input '<' in function "calculateAge" [ERR 102] Line 1:46 mismatched input '>' in function "calculateAge" Parser returned a null Package I see quite a few JIRAs about incomplete exception handling - GUVNOR-741, GUVNOR-690, GUVNOR-536, should I add the above to any of them? Whatever, an error is an error, but here comes the real problem: After the above I come to realize that each analysis of a package keeps adding the results of the previous ones, so the Errors/Warnings list just grows and grows. An old error will always come again even though the item it refers to is not even existing anymore (so I cannot analyse/verify anything reliably). I renamed the above function, I edited it so it doesn't have the chevrons, its code can be validated fine, but nevertheless Guvnor keeps throwing the same error 500 and the JBoss console keeps complaining about the oooold function calculateAge and its chevrons each time I verify or analyse. And it does that by repeating the message for each retry once more. Either the error list is not cleaned after the verify, or some artifacts live too long. Logout and relogon keeps the list, but restarting JBoss solves the problem. . I really have the feeling GUVNOR-1499 has the same underlying problem... For the record: I'm on 5.2.0.Final on JBoss 6, Java 6 on Windows XP. Thank you very much, JC
