Vishnu, tell us your jdev version, please!

You should read better describe what you want to do (maybe read https://tompeez.wordpress.com/2016/10/14/how-to-ask-questions-in-otn-spaces/ ).

If you set a child node as selected the parent node doesn't discloses itself, you have to do it yourself. Once all nodes to the child are disclosed, you don't see the 'go to top'. If you know the child node you create a new RowKeySet and add the child node to it. then you traverse the tree up  and add each parent node to the rowKeySet until you reach the root node which you have to add too. This should do it. For an implementation you can look at https://blogs.oracle.com/jdevotnharvest/entry/how_to_programmatically_disclose_a which shows how to implement this.

Apologize for not putting the question clearly.

I'm using Jdev 11.1.1.7.

Yes, I do understand that I have to traverse through the tree and find respective parents to disclose a particular node.

But my question is regarding setting selected row and not disclosed rows. I'm able to disclose rows as required.

Upon setting selected keys and refreshing the tree, I don't see entire tree but only the selected node. (with a blue arrow as shown in my screenshot)

Is there a way to avoid this behavior, so that the blue arrow doesn't appear and just required row is selected and entire tree is displayed as-is.

-Vishnu

Yes,  the blue arrow means that you have set the root node and not selected node.

How have you implemented the selection?

Thanks for the responses, Timo.

I've noticed that it is not because of selected node but because of 'setFocusRowKey()'.

I'm trying to disclose necessary nodes, select a particular row and bring the focus to that row. (automatically scroll to that row)

disclose and select are working fine, but focus is bringing in the blue arrow with 'go to top'.

-Vishnu

So is the problem solved?

I made a small test case which is working fine. I can search for a node in a tree and select it.

My search is for the LocationId. I enter 1200 and on click on select the node is searched the tree and selected

Timo

Appreciate your interest.

No, problem isn't solved.

It is actually an extension to the example you used. Let's say there are 100s of rows that aren't visible without scroll, and the selected row is somewhere at the bottom. To focus the selected row, I'm using setFocusKey(), which brings in the arrow.

-Vishnu

thank you, Morgan. That worked.

Hi Vishnu,

Glad I could be of some help

Cheers
