Jface treeviewer refresh not working properly [message #1810619]

Hi,

We are migrating our current eclipse RCP client to RAP. We have a view which has a Jface Treeviewer with refresh functionality wherein latest model data is fetched and tree is refreshed.

The issue is treeViewer.refresh(true) causes several items from the tree to disappear. More specifically, the top level elements disappear and only some of the children elements are shown.

Here is the code which runs on refresh command:


        treeViewer.setContentProvider(.....);
        treeViewer.setLabelProvider(......);
        treeViewer.setSorter(........);
        treeViewer.setInput(<latest root element>);

        IContentProvider contentProvider = treeViewer.getContentProvider();
        if (contentProvider instanceof NavigatorContentProvider)
        {
            ((NavigatorContentProvider) contentProvider).reset();
        }

        treeViewer.refresh(true);

I have attached screenshots for the issue.

The same code works without any issue on RCP client.

Could you please help with this?

Thanks
Ganesh

Hi,

without a self-running snippet to reproduce the issue I can't say much about it. Please open a bug report and attach your demonstration code there.

Regards,
Ivan
