[news.eclipse.platform] Re: "Open" menu action in Project Explorer

["Rahul Kamdar" <rtkamdar@xxxxxxxxxxxxxxxxx>]

Hi sorry for a late reply, I happened to check this today only...

Regarding the enablement clause:

<enablement>

<or>

<and>

<adapt type="org.eclipse.core.resources.IResource/IFile" />

<test

property="org.eclipse.core.resources.projectNature"

value="">

</test>

</and>

</or>

</enablement>

You need to add your own action and this needs to go into the "Open Group". 
However, if you find that there are two "Open" actions coming up, that is 
not the expected behavior. Can you post code from your plugin.xml where you 
have contributed the actionProvider and also snippets from your class 
implementing the commonActionProvider. Maybe we can identify what's going 
wrong.
