JBoss Developer Studio The following line in a DRL results in a NullPointerException of unknown location EasyApp(eaPremiumMode not in ("A", "S", "Q", "ABC", "SS)) Note that the last string on the line is not closed. The eclipse plug-in didn't show the problem clearly (by turning subsequent lines green) - it took a long time to track down (commenting out rules until the error went away). Should I submit a bug on this? -- View this message in context: http://drools.46999.n3.nabble.com/Unclosed-string-results-in-NullPointerE...
