Hi all,
i have some jface problems when loading a custom bundle with commands,
handler, menus and bindings.
I am using the following lines of code to install a bundle:
Bundle b = bundle.getBundleContext().installBundle(editorDiagramName, in);
Where 'bundle' is the bundle that contains a custom extension point, it
is resolved by using the ContributorFactoryOSGI.resolve method and 'in'
is the input stream to the bundle.
There is no problem loading the bundle, but when its content is
activated, jface does not seem to like my stuff :)
1. When the bundle contains binding extensions, the BindingManager
throws a lot of undefined context exceptions. This exception is thrown
because the BindingManager tries to reload all the Bindings, even if the
Contexts not have been initialized yet.
(The error log can be found at :
https://bugs.eclipse.org/bugs/attachment.cgi?id=151053)
Well that may be solved by adding a check if the context has been
activated before getting the id, but i wonder why this exception is
thrown anyway.
When the platform loads a bundle by using lazy-loading, there are no
exceptions, so why is it thrown here?
2. Same situation: Loading a bundle during runtime.
If the bundle contains a menu contribution with a sub menu (at least
i've never got an exception when only adding simple menu commands),
the ContributionManager throws an index out of bounds exception when
inserting the item.
Same question: Why does that never happen when the platform is loading
bundles but when i am manually loading them ?
Is it a timing problem ? Do i need to have special settings when
lazy-loading stuff that interacts with jface?
Exception trace for second error:
