30EA2/30EA1 : Selection Behavior on Master-Detail Result Grid

Question

Hi,
Tested on both Win XP and Win 7, SQL Dev with the included jre.
I notice quite annoying behavior on Master-Detail Result Grid.
This happen on either Report with master-detail layout (i.e Active Session from the built-in report), popup describe on several tabs, and objet viewer especially on Table's Partition tab.
Here are the things :
1. Why made the selection on header result cell lose its focus after selecting one?
I understand, that SQL Dev needs to re-query for displaying the detail.
But why not made the selection focus, goes back to the selected (shown by the rectangular yellow line around the cell) header cell ?
2. Point 1 leads to another problem.
In order to copy the cell value, we have to click once again to select the cell value (shown by the rectangular yellow line around the cell) from the master grid and press CTRL + C.
What a waste extra effort here.
Moreover, I noticed some strange thing on object viewer Table - Partition tab.
It is really hard to copy the cell value from this tab, i.e copying the partition name value.
Everytime I press CTRL + C to copy its content, suddenly the cell goes to edit mode, which is read-only of course. CTRL + V to paste seems does not work, like it has nothing in the clipboard to be copied.
And, navigating the cursor from this point would cause the pointer goes to the last character of the cell content, as well as selecting the content using CTRL + Home, is useless.
Is it because there is no detail record on the detail (in this case Subpartition) tab?
However Partition tab on Popup Describe, which supposed to have the same behavior, CTRL + C works just fine.
Is this an expected behavior?

Hi Raghu,

When changing selection in Master grid, the Child grid is repopulated. This also cause the Master grid to lose focus which makes navigating & copying from master requiring to select a cell in it again.
Right ?
Yes. That's right.
I see, you use Child as referred to me as Detail, on which I get the name from Reports (when create User Defined Reports on SQL Dev, there shows Master on the top panel and below is Detail. :-)
If yes, this is the same issue as reported in other thread where executing Statement Runner in worksheet, the worksheet loses the focus & the results grid gets the focus.
The grid has got focus hungry & I am fixing it.Maybe this explains, why there is a small delay before showing the result grid.
I tried to compare from SQL Dev 2.1.1 and 3.0EA1.
3.0EA1 gets a little late (a second maybe) when displaying the result.
For the last item, here are the things :
1. From the Schema Browser (Left Hand Side), expand Tables.
2. Select a partitioned table from the tree, there shown Object Viewer (on Right Hand Side) for that Table. -- I use the term Object Viewer as shown on the Preferences : Automatically Freeze Object Viewer Windows
3. Select Partitions tab
4. Click a cell on Master grid, there you go the losen focus
5. Now, click once again to select
6. Press Ctrl + C
7. It suddenly change to cell's edit mode (of course its read-only cell)
Navigating the cursor from this point would cause the pointer goes to the last character of the cell content, as well as selecting the content using CTRL + Home, is useless
8. Now, go to the worksheet, and press Ctrl + V, nothing happens as if the copied cell doesn't get into the clipboard.
