[pde-dev] Obtaining extensions information for target image

[Brian de Alwis <bsd@xxxxxxxxx>]

Hi Wassim.  A while back, you asked somebody on pde-dev:

I'm trying to walk the PDE plug-in models to perform some checks
for the target image, some of which include examining the contents
of any declared extensions.  Unfortunately the PDE models rarely
have the content of any extensions.  My code is roughly:

    IPluginModelBase pluginModels[] =
	PDECore.getDefault().getModelManager().getActiveModels();
    for (IPluginModelBase pluginModel : pluginModels) {
	IExtensions pluginExtensions = pluginModel.getExtensions();
	for(IPluginExtension ext : pluginExtensions.getExtensions()) {
	    for(IPluginObject child : ext.getChildren()) {
		// do something
	    }
	}
    }

But there are the `ext.getChildren()' returns an empty array except
for extensions to one of four special extension points.  I've tried
creating my own PDEState, as well as explicit instances of
WorkspacePluginModel, to no avail.

How should I be doing this?  Should I be creating my own instance
of WorkspacePluginModel?  PluginModel?

Thanks for your help.
