Created attachment 135623 [details] MultiViewCloneableTopComponent exception Due to failing Multiview tests in our EE area I found out that the fix for issue #228448 probably made several regression in the Multiview code which should be fixed. - our DDDataObject calls openView() method which should get the index of opened page... but the index doesn't correspond any more since XmlMultiViewEditorSupport#openView looks for available Perspectives where are all of them twice obtained twice - the original reason is likely inside MultiViewPeer#setMimeLookup() - if I force correct index to be chosen, I'm getting NPE I attached from MultiViewCloneableTopComponent where is no mention about our DD loaders so I suppose that the issue lies somewhere in the multiview too Related tests are the ddloaders ones shown in every our build: http://bertram2.netbeans.org:8080/job/web-main-tests/lastCompletedBuild/testReport/ Please evaluate. Thanks a lot.
No visible difference in behavior. Modified the fixed MVElements' indexes to make the tests pass. Fixed: http://hg.netbeans.org/core-main/rev/a9f31c416a16
Ok. Thanks for quick fix.
