Mismatched types in field constraints ------------------------------------- Key: JBRULES-261 URL: http://jira.jboss.com/jira/browse/JBRULES-261 Project: JBoss Rules Issue Type: Task Security Level: Public(Everyone can see) Components: Rule Assemply/SPI Affects Versions: 3.0.1 Reporter: Michael Neale Assigned To: Mark Proctor Priority: Minor Fix For: 3.1-m2 Problem: If a rule compares two fields and one of them is a char and the other one is a String, the match is always negative. No type-mismatch error or warning is displayed. This can be quite confusing. The attached Eclipse project illustrates this problem. Suggested Solution: If all information is available at compile-time an error should be generated on type mismatches. Otherwise there should be a warning during run-time and maybe a type conversion attempt.
