Extension point namespace change [message #23691]

Hello,
after updating RAP from CVS and switching the namespaces of the extension to
the new one I get an error that my perspective was not found.

In the plugin.xml I have the following code:

<extension
point="org.eclipse.ui.perspectives">
<perspective
class="ag.ion.rap.internal.ui.perspectives.BasePerspective"
fixed="true"
icon="icons/full/eview16/base_perspective.gif"
id="ag.ion.rap.perspectives.base"
name="%perspective.base.name"/>
</extension>

The error stacktrace is:

java.lang.RuntimeException: org.eclipse.ui.WorkbenchException: Unable to
create perspective 'ag.ion.rap.perspectives.base'. There is no
corresponding perspective extension.

Hello,
I figured out, that if I exclude the plugins "org.eclipse.core.expressions"
and "org.eclipse.update.configurator" from my launch configuration and call
my perpsective that does not use the "org.eclipse.core.expressions", then it
works. I definitely need the "org.eclipse.core.expressions" plugin and I
have no clue why my perspective can not be loaded if I include this plugin
and
use its functionality. This error only occury since I updated from CVS today
and corrected the namespaces.

Any ideas?

Thank you,
Markus

Hi,

I just checked your problem and I don't think that the problem is
'org.eclipse.core.expressions'. I used the propertyTester extension without
problem. The trouble is caused by the 'org.eclipse.update.configurator'
since it resolves all your target plug-ins including 'org.eclipse.ui'. I
guess this causes the namespace conflict. If you need the configurator
plug-in then you should create a seperate target where no RCP-UI-plug-ins
are available.

Hope that helps!

Ciao
Frank

Wow, sometime having over 160 Plugins can lead to some confusion. I had a
"core" plugin that my RCP and RAP was using. This "core" plugin added a
projekt nature. Project natures are in the plugin
"org.eclipse.core.resources" and this plugin has a dependency to
"org.eclipse.core.runtime.compatibility". Now the
"org.eclipse.core.runtime.compatibility" plugin has a dependency to
"org.eclipse.update.configurator" plugin which after the namespace changes
has a problem with RAP.

So, You were right, Frank. After solving this dependency by changing the
structure in my projects everthing works again.

Thanks,
Markus
