When a prop becomes invalid, the various config edit views are supposed to display a red message to the user saying e.g. "The following properties have invalid values: [Foo] - the values must be corrected before the configuration can be saved.", but this is not happening due to the bad information in fired prop value changed events.
[master dc7b71b] (http://git.fedorahosted.org/git/?p=rhq/rhq.git;a=commitdiff;h=dc7b71b) fixes this.
Verified on build#619 (Version: 4.1.0-SNAPSHOT Build Number: 7911e52) It displays a red mark and a message for invalid property (Ex: : The following configuration properties have invalid values: [Banner]. The values must be corrected before the configuration can be saved.) Also Verified for a group config (Ex: The following configuration properties have invalid values and must be corrected before the configuration can be saved: [[Plugins Directory]] )
