The current node to display all the levels at the atomic scale
Hi allIf anyone has example of expand/collapse the current node to display all the levels at the atomic scale. Please post here. I appreciated the help.
Thank you
James,
try adding a condition just before current node if the next node id is null or not.
Thus, the update procedure will be like that.
PROCEDURE Expand_Collapse_Node (Tree_Name IN VARCHAR2 , Trigger_Node IN VARCHAR2, Str_Type IN VARCHAR2 DEFAULT 'COLLAPSE') IS
Item_Id ITEM;
Current_Node FTREE.NODE;
Starting_Node_Level NUMBER;
Current_Node_Level NUMBER;
BEGIN
IF Trigger_Node IS NOT NULL THEN
Item_Id := FIND_ITEM(Tree_Name);
IF NOT ID_NULL(Item_Id) THEN
Current_Node := Trigger_Node;
Starting_Node_Level := FTREE.GET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_DEPTH);
LOOP
IF FTREE.ID_NULL(Current_Node) OR (Current_Node_Level = Starting_Node_Level) THEN
EXIT;
ELSE
IF Str_Type = 'EXPAND' THEN
IF FTREE.GET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_STATE) = FTREE.COLLAPSED_NODE THEN
FTREE.SET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_STATE, FTREE.EXPANDED_NODE);
END IF;
ELSIF Str_Type = 'COLLAPSE' THEN
IF FTREE.GET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_STATE) = FTREE.EXPANDED_NODE THEN
FTREE.SET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_STATE, FTREE.COLLAPSED_NODE);
END IF;
END IF;
Current_Node := FTREE.FIND_TREE_NODE(Tree_Name, '', FTREE.FIND_NEXT, FTREE.NODE_LABEL, '', Current_Node);
IF FTREE.ID_NULL(Current_Node) = FALSE THEN
Current_Node_Level := FTREE.GET_TREE_NODE_PROPERTY(Item_Id, Current_Node, FTREE.NODE_DEPTH);
END IF;
END IF;
END LOOP;
END IF;
END IF;
END Expand_Collapse_Node;
Kind regards
Manu.

HelloI was trying to get a function "SHOW ALL" on the master - detail page
the detail table is a table of advancec.
Please help me with entries on how to make the feature "SHOW ALL",
Currently, you must click on ': show ' for each record to the master level to display the data of the child.
Trying to reach 'Show all' then featured on click this key records on the page "expands" showiing master records with respective detail records.
Concerning

Hello
You should not set DetailFlag = 'Y' in the whereclause, because there is no such record.
Also detail flag are transitional attribute and not the query column, hence the error "invalid identification Code.
I asked you to use DetailFlag as a column of query with the static value 'Y '.
for example:
SELECT 'Y' detail_flag
Of
This will display all the records in the table in expanded format. If you want conditionally then use decoding on some binding settings.
For example:
SELECT DECODE (: 1, "SHOWALL", "Y", "N") detail_flag
Of
This connection parameter must be passed each time you want to run the query for the table.
Kind regards

How to set programmatically the current node in a tree view of the ADF.
Hello
I'm trying to understand how to set programmatically the current node in a tree view of the ADF.
My use case example is quite simple; If we take the sample application ADF Summit where under Management Summit, we have a tree view on the left with a list of high level of the country which in turn contain a subset of customers; then, in the right pane, we the customer detail information.
What I'm trying to achieve is a solution by which I can add a new customer, commit and then to the tree show the client newly created as the currently selected entry.
I use a pop-up dialog box to create my new entry of the customer and everything works well in this area, and my newly created folder is saved in the database.
I know how to force the tree to cool off, but what I can't understand is how to do so, it highlights the newly created folder.
Any help would be much appreciated.

No current row to display by clicking the Lov
Hi all
I packed a lov to a column. It is a column in the search page. This search page should take some input parameters and the results by calling the api. I created this page by using the transient variable entry and output columns. I added this lov to an input column. "I get this error *" no current line for the view "*." I'm new to the FPÖ. After I have read the discussions, what I realized is that there could be two reasons for this error.
1. VO uninitialized. -Some body give me a piece of code, how to initialize a VO?
1 VO query returns 0 number of lines. -I don't have any query in my VO. Everything I have is 4 trasient variable.
Thanks in advance.Double wire
You can use under your vo on AM initialization method calling processRequest
public void createRow() { OAViewObject vo = (OAViewObject)getEmployeeFullVO1();//Here your VO instance name instead of EmployeeFullVO if (!vo.isPreparedForExecution()) { vo.executeQuery(); } Row row = vo.createRow(); vo.insertRow(row); row.setNewRowState(Row.STATUS_INITIALIZED); }
Thank you

After 20.0.1 a few hours ago, click Update right displays all THE menu options, do not work a lot (all?), as 'view page source', 'open in a new tab' etc etc.
To clarify, this happens if you have the active Firebug 1.10.6 addon.
You can fix it by updating to the version of Firebug 1.11.2Here's how:
Go to your add-ons Manager, right-click on the Firebug add-on and select 'Find updates'.Hope that helps.

Satellite A100: Cannot display all the files on any CD or DVD
Well straight.
My brother bought a new laptop today.
However, there seems to be a problem. When you go to my computer and click on the CD icon, nothing happens. When right click and select "Explorer" hard disk take it just straight up one explores the desktop for some reason any. So, it may not display all of the files on any CD or DVD.

Hello
I don t think that the driver is up-to-date. The CD/DVD drive using the common drivers of Windows OS and these drivers should work without any problems.
However, try to remove the drive from Device Manager. After restart of the operating system should recognize the drive again. Check it out. -
poor print quality, clean the heads, all ink levels ok,
printing lines, horizontal, poor quality, some missed lines quality fakes. Cleaned heads, nozzle, all ink levels fine
Hello Stephenagar,
What operating system you run on your computer? (Windows 7, Vista or XP?)
What is the printer brand and model? (HP, Canon, Brother, etc..)
I suggest that you try runing the Microsoft FixIt tool is in the following article: -
Cannot change the login screen to display all users.
I'm unable to change the sign on screen to display all users. It is said to remove the client service for netware (CSNW), when I go to remove only the open is available. The service has not been started.
Where did you go to remove the Client Services for Netware?
Go to network connections (start > run > ncpa.cpl > OK)
Right-click on the icon for your network adapter (most likely, Local area connection), and then select Properties
On the general tab, you should see a list under "this connection uses the following items."
Select the Client Services for Netware, click to remove the check mark, and then click Uninstall.
OK your way out.
Restart (it is not automatically)
After Windows starts, go to control panel > user accounts > Change the way users log on and outside
Select the options you want and click on apply changes.The list of questions should normally (personal computers) include only 4 following:
Client for Microsoft networks
QoS Packet Scheduler (optional)
Sharing files and printers for Microsoft Networks (only if you want to share files or printers)
Internet (TCP/IP) ProtocolIf you do not see Client Services for Netware on the general tab of the connection to the Local network or if you still have the problem after uninstalling it this connection, examine the properties of other components in the network connections. For some of them (e.g. Dial-up), the list of questions is on the network rather than on the general tab tab.
If you can't find the Client Services for Netware for ALL network connections (and therefore cannot remove), reinstall it, and then follow the instructions above to uninstall.
To reinstall:
1. go in the network adapter Properties/General tab you use and then click on install
2. make sure that 'Client' is highlighted, and then click Add.
3. highlight "Client Service for Netware", click OK
4. leave your PC restart. -

On the "rocket", when you select the name of an artist in the music menu, it displays a list of all titles of the album by that artist. At the top of the list is the ability to 'play together', but I can't understand how to display all the songs of the artist in a large list, regardless of the album. It would be useful if you know who did the song, but don't know what album it's on. Is there a way to get the "rocket" to show you such a list? Thank you.
