editElement method of TreeViewer [message #467827]

Hi,

I am facing a problem in editing a tree item.

I have written one action like when I click on edittree button the
selected item is in editable mode..

First I will explain the tree and then the problem, The tree structure
is Cust1 is the first level next one is list of studies for that Cust1(say
Study1, Study2)...and the third and last level is Experimens list under
each study...
one experiment can be more than one study...

Suppose data is Cust1 -- Study1 -- Exp1
-- Exp2

-- Study2 -- Exp1
-- Exp2

When I select Exp1 under Study2 and click on edittree button, the Exp1
under Study1 is getting selected..

I think the problem is with the editElement() method,

treeItem = treeViewer.getTree().getSelection()[0];

treeViewer.editElement(treeItem.getData(), 0);

I think editElement method is searching the tree and selecting the
treeItem which ever it encounters the same model....

I hope you got the problem...

Thanks,
Swetha

Hi,

Are the Exp1 and Exp2 the same object instances? If you you need to pass
a TreePath to editElement to uniquely identify the element you want to edit.

Hi,

Exp1,EXp2 are the instance of Experiment domain object.....

I thought the same to pass TreePath to the editElement() method,

how can I get the treePath for the selected tree Item.. I tried all the
methods to get access to the TreePath..

Thanks,
Swetha
