[pde-dev] Problem with context-sensitive help from multiple plug-ins
|
Hi all,
I'm trying to contribute some topics to the context-sensitive help of the Breakpoints view from my own plug-in.
I want to have my contributions merged with the existing ones.
In my "contexts.xml" file below, If I specify a <description> for the context id I'm using, I cannot contribute something without overwriting the existing topics.
And if I don't, I have a null pointer exception (see the log file below).
Any help would be much appreciated.
I'm using Eclipse 3.3RC4.
in plugin.xml:
<extension
point="org.eclipse.help.contexts">
<contexts
file="contexts.xml"
plugin="org.eclipse.debug.ui">
</contexts>
</extension>
in contexts.xml:
<contexts>
<context id="breakpoint_view_context">
<command serialization="SOME.COMMAND" label="SOME LABEL"/>
</context>
</contexts>
