Hi,
I am trying to extend p2 by addition touchpoint actions. The problem is that I am unable to reference a fragment in a fragment's touchpoint action (I am getting the host IU instead).
In the example below, when "actionOnFragment" is executed, the "iu" parameter is set to the instance of the "something/1.0.0" installable unit (as fragments's host). However, I need to get information about the fragment.
Is there a way to find which fragment contributed the action being executed?
Regards
Filip
Example:
<units size='2'>
<unit id='something' version='1.0.0' singleton='false'>
<provides size='1'>
<provided namespace='org.eclipse.equinox.p2.iu' name='something' version='1.0.0'/>
</provides>
<touchpoint id='org.eclipse.equinox.p2.osgi' version='1.0.0'/>
<touchpointData size='1'>
<instructions size='1'>
<instruction key='install'>
someAction()
</instruction>
</instructions>
</touchpointData>
</unit>
<unit id='fragment' version='1.0.0' singleton='false'>
<hostRequirements size='1'>
<required namespace='org.eclipse.equinox.p2.iu' name='something' range='1.0.0'/>
</hostRequirements>
<requires size='1'>
<required namespace='org.eclipse.equinox.p2.iu' name='something' range='1.0.0'/>
</requires>
<provides size='1'>
<provided namespace='org.eclipse.equinox.p2.iu' name='fragment' version='1.0.0'/>
</provides>
<touchpoint id='org.eclipse.equinox.p2.osgi' version='1.0.0'/>
<touchpointData size='1'>
<instructions size='1'>
<instruction key='install'>
actionOnFragment()
</instruction>
</instructions>
</touchpointData>
</unit>
</units>
