[pde-dev] How to Annotation for ProblemMarkers

[Ram Mohan <ram.mohan@xxxxxxxxxxxxxxx>]

Hi,

I am developing an editor for a new language. 
I am able to mark the errors on the vertical ruler properly but i wasn't able to annotate them(when mose moves over these markers) with error messages.

I have added both extensions "annotationTypes and markerAnnotationSpecification" and mapped them to markertype.
But, I couldn't see any annotation when i move the cursor over the error marker.

I couldn't find any example and tutorial on how annotations can be added for markers.
It appears to me that i need to add some MarkerListener to SourceViewerConfiguration. 
am i correct? Any pointers in this regard would be very helpful.

Regards,
Ram

A snippet of my editor plugin.xml

   <extension
         id="xmlProblem"
         name="XML Problem"
         point="org.eclipse.core.resources.markers">
      <super
            type="org.eclipse.core.resources.problemmarker">
      </super>
      <persistent
            value="true">
      </persistent>
   </extension>

   <extension
         point="org.eclipse.ui.editors.annotationTypes">
      <type
            markerSeverity="2"
            markerType="TACT_Editor.xmlProblem"
            name="TACT-Editor.TactError"
            super="org.eclipse.ui.workbench.texteditor.error">
      </type>
   </extension>

   <extension
         point="org.eclipse.ui.editors.markerAnnotationSpecification">
      <specification
            annotationType="TACT-Editor.TactError">
