[ https://issues.jboss.org/browse/GTNPORTAL-3118?page=com.atlassian.jira.pl... ] RH Bugzilla Integration commented on GTNPORTAL-3118: ---------------------------------------------------- Lucas Ponce <lponce(a)redhat.com&gt; made a comment on [bug 906487|https://bugzilla.redhat.com/show_bug.cgi?id=906487] The WebUI layer uses hashCode() function for some UI components IDs. The IBM JDK returns some negative hashCodes() for components where OpenJDK or SunJDK returns positive. The drag and drop javascript module filters the "-" symbol for these elements, so when you have a negative ID the NPE is thrown. I've fixed this one, forcing to have positive IDs for UI components. I've performed several tests both with OpenJDK and IBM JDK and I can't reproduce the error with this patch. PR sent attached in JIRA. Lucas -- This message is automatically generated by JIRA.
