I am using a view which extends CommonNavigator,

The view provides a Tree Viewer which is constructed using our model objects

I have a wizard which adds a new object to the tree,

How do I refresh the tree viewer to expand and set the selection on the newly created object?

Hi Aravindhan,

I would try to call

AbstractTreeViewer.add(Object parentElementOrTreePath, Object childElement)

from my content provider and then

TreeViewer.setSelection(new StructuredSelection(childElement), true)

Hi Aravindhan,

You must call TreeViewer.refresh() to refresh the viewer completely with information freshly obtained from this viewer's model and call TreeViewer.refresh(element) to refresh the viewer starting with the given element.

You must avoid the use of the method AbstractTreeViewer.add(Object parentElementOrTreePath, Object childElement) because it will not be synchronized with your data model.

Kind Regards,

Hussein
