[news.eclipse.tools] Re: Dynamic preference nodes - SEVERE

[adrian <stori@xxxxxxxxxx>]

I should mention that I use the PreferenceNode(String id, IPreferencePage
preferencePage) constructor - therefore PreferenceNode.label is always null
(so displaying the treeItem when the page is gone fails, as getTextLabel()
returns null), and createPage() is no good, as there is no
PreferenceNode.classname.

The PreferenceNode(String id, String label, ImageDescriptor image, String
className) constructor doesn't work - in createPage(), page =
(IPreferencePage)createObject(classname) fails (although it works fine when
I do it in my code, when extending PreferenceNode!?).  Also, I prefer to use
the former constructor, i.e., have the PreferencePage instantiated by me
(with a custom constructor)...
