Build Identifier: I20100603-1500 I have the following in my plugin.xml. Everything seems to work ok.. till I refer to a non-built in (inherited) marker type in markerContentGenerator. If I do that, I get a NPE from, and it doesn¡¦t seem to if I close the view and reopen it from Wndow->Show View. <extension point="org.eclipse.ui.views"> <view

Sorry I should have mentioned this plugin.xml belongs to com.intel.compiler.cdt.managedbuilder.ui. And, it seems that this problem is resolved if I use "id=GAPMarkerType" instead of id="com.intel.compiler.cdt.managedbuilder.ui.GAPMarkerType" in the marker definition. <extension point="org.eclipse.core.resources.markers¡¨ id="com.intel.compiler.cdt.managedbuilder.ui.GAPMarkerType"> <super type="org.eclipse.core.resources.problemmarker"/> <super type="org.eclipse.core.resources.textmarker"/> <attribute name="description"/>^M <persistent value="true"/> </extension> I'm keeping this open in case someone wants to add to the documentation that you don't need the "whole name" in the definition ID.
Slight correction. <attribute name="description"/>^M shouldn't be there
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
