WHEN-TREE-NODE-EXPANDED not fire with keyboard in FORMS 10G

I have a Hierarchical Tree. When i click in any node with mouse, works fine.
When i use the key rigth and left of the keyboard, the tree expanded, but not fire the WHEN-TREE-NODE-EXPANDED.
In FORMS 6i works fine.

It's a bug 4509399. There is a oneoff patch on Metalink:

You posted the same question 2 days ago and I've answered you, you didn't even provide an exact version of your forms.
Posting again will not change your problem.

WHEN-TREE-NODE-SELECTED Action required..!

Hello all,
i am using a tree for the first time, i want to reflect the value of the node's id and desc in it's database item where they r inserted.
The problem is the desc is not displayed NOT.
But the node id is working just fine..Why ?
Can anyone help me pls..?
i am using the following code:
WHEN-TREE-NODE-SELECTED Trigger:
:EQUIPMENT_TYPE_D := :SYSTEM.TRIGGER_NODE;
--The above returns the item_id of the node.
BEGIN
       SELECT EQUIPMENT_TYPE
       INTO :EQUIPMENT_TYPE
       FROM INSP_EQUIPMENT_TYPE
       WHERE EQUIPMENT_TYPE_D = :EQUIPMENT_TYPE_D ;
Exception
When No_Data_Found THEN NULL;
When Others THEN
                                 Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);
                                 Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);
END;Regards,
Abdetu..

The WHEN-TREE-NODE-SELECTED trigger fires twice, it fires when selecting the node and when deselcting the node.
First make sure that you SQL works in SQL*Plus, Handle your EXCEPTION correctly, remove the NULL from your exception and put a message, maybe your SQL is not returning any rows.
add the below if condition in your trigger. This will make your code to be executed only when you select the node and not when you deselect it.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
...    --Your execution code
END IF; If your item name is the node's label itself you can easily do this:
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
:your_block.your_item := FTREE.GET_TREE_NODE_PROPERTY(HTREE$, :SYSTEM.TRIGGER_NODE, FTREE.NODE_LABEL);
END IF; Tony

Tree item when-tree-node-selected fires differently from 6i to 10g.

In forms 6i, when you keyboard navigate between tree nodes, the wtns trigger will fire. In 10g it does not. In 10g, it will fire if you press the tab key or mouse click on a node.
Anyone know if this was done on purpose?
I ran into this after finally trying my props.fmb in 10g. It works fine in 6i, but not in 10g
copy of my form is here:
http://www.tailboom.com/oracle.php
Forms [32 Bit] Version 6.0.8.18.3 (Production) cleint server
Forms [32 Bit] Version 10.1.2.0.2 (Production)
I wrote most of the tree handling code for oracle apps APPTREE. This is the code that most if not all tree's in apps uses to build standard tree. So I have a pretty good understanding of the forms tree item. And know the wtns fired for web forms 6i on every node like 6i client server. This is very strange IMO.
Thanks.

Oleg,
thanks for the reference. Although the bug you identify deals with when-tree-node-activated, it is possible they fixed the when-tree-node-selected issue at the same time. With my test tree, i can currently duplicate both issues. I tried to download the patch, but it is only available for linux and unix. No windows patch. I don't have my linux env up and running to where I can test yet. So I can not confirm.

TREE-NODE-EXPANDED

Hi all
i have a problem in the tree node. i was upgrading the application from forms9i to forms10g. but after the upgrade the tree node does not work as before.
every time i try to expand the tree with the keyboard ( the arrow key - the enter key ) i need to press the (tab key) to expand the tree .
also when i try to open any form from the tree by pressing the (enter key) i need to press the (tab key).
but when i use the mouse (double click) it works well.
Thanx.

Htmlb:tree differentiate between nodeclick and tree node expander click

Hi,
how can i differentiate between nodeclick and tree node expander (to get to its children) click in my event processing in htmlb:tree element.
What i am trying to achieve?
Onload just load root node and its immediate children.
On node expand get the children of the current node and modify htmlb:tree table2 with additional node inofs.
on node click call some client function.
But my issue is that i am not able to differentiate between node expander click and node click in my event handling. Any help on this is appreciated.
(I am not using MVC)
Thanks in advance.
Regards
Raja

After reading your weblog I think I understand better. I did some testing with my example. I am using the toggle = "true", so that the page returns to the server each time an expander is selected.
<htmlb:tree id = "myTree1"
 height = "75%"
 toggle = "true"
 title = "<otr>EQI Reporting Tree</otr>"
 width = "90%"
 onTreeClick = "myTreeClick"
 table = "<%= application->selection_model->itview %>" >
</htmlb:tree>
However I have not added any coding in my event handler to respond to the expander event. I only respond to myTreeClick (which loads some data for the given selection). The BSP tree element itself must be doing the hard work for me.
if event_id cs 'tr_myTree1'.
 data: tree_event type ref to cl_htmlb_event_tree.
 tree_event ?= htmlb_event.
 if tree_event->server_event = 'myTreeClick'.
 clear appl->message1.
 appl->selection_model->get_chart_data( appl = appl
 node = tree_event->node ).
 endif.
endif.
I pass my entire tree defintion to the element. It appears that it only sends visible nodes to be rendered. When the expander is selected, I don't have to do anything, the tree re-renders with only the newly visible rows.
I tested and turned off the toggle (toggle = "false") and my page took forever to load because it was sending all the nodes to the frontend on the first load.

WHEN-TREE-NODE-SELECTED

Hello alllll
i have a master-detail block besides a tree block
All i wanna do Simply and logically is to select a tree node then a Master-Detail records related to this tree node is to be retrieved...
_i have the following code in the WHEN-TREE-NODE-SELECTED Trigger as follow:_
DECLARE
htree ITEM;
 node_value VARCHAR2(100);
BEGIN
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
-- Find the tree itself.
htree := FIND_ITEM ('BL_TREE.IT_TREE');
-- Find the value of the node clicked on.
NODE_VALUE := FTREE.GET_TREE_NODE_PROPERTY( htree, :SYSTEM.TRIGGER_NODE , Ftree.NODE_LABEL );
 GO_BLOCK ('STP_COMPANIES');
EXECUTE_QUERY;
 END IF;
END;The above code retrieved data as a whole
but i want 2 filter the data selected from the tree node as i said 2 be displayed as filtered by the tree selection.
so i used the following code as follow:
GO_BLOCK ('GL_COST_CENTERS');
 set_block_property('GL_COST_CENTERS', DEFAULT_WHERE, 'COMPANY_ID ='||
 ftree.get_tree_node_property('BL_TREE.IT_TREE', :SYSTEM.TRIGGER_NODE, FTREE.NODE_VALUE));
EXECUTE_QUERY;Any help will be appreciated...
Thanks in Advance..
Regards,
Abdetu...

Hello thanks for reply,
STP_COMPANIES your detail block? no it's the master
gets the "Label" of the tree node not the value of the selected nodei tried both but nothing retrieved...!
i thought that the value is the serial of the node and the lable is the text displayed on the tree node no ?
Is this code in the same When-Tree-Node-Selected trigger or a different trigger?yes WHEN-TREE-NODE-SELECTED as my post titled...
is GL_COST_CENTERS the master block? no it's the detail ; every company --- has many <- cost centers
are the tables related? yes
just query the master table and the detail table will automatically be filter through the relationship?i did and it works filtering through the company_id, But what i wanna do is 2 filter the data displayed in the two block Master-Detail according 2 the selection of the tree
Say i selected the ....
 + Assets node
 |
 |------ - Furnitures 's node is selected so alll the related details of the furniture is displayed in the Master-BLock
 | |
 | +----chairs
 | |
 | +----tables
 |
 +----- LAnds
 |So the Tree is used 2 Query or retrieved the selected node's data accordingly...
hope i well explained my issue ..!
is it possible 2 do that ?!
Thanks Again..

Abdetu...

Tree Node selected not firing all the time

I have a tree menu that calls other forms when the user selects a tree branch (see
When-tree-node-selected trigger below).
This works fine, but if the user closes the form and want to re-open it, the trigger doesn't fire unless the user clicks off the branch item and back on it. How can I make it work whenever the user clocks the branch item?
if :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' then null;
node_value := Ftree.Get_Tree_Node_Property(htree, :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE);
open_a_form(l_form,l_module,l_form_code);
end if;

Have you tried setting the node the node to deselected programmatically?

OPEN FORM WHEN-TREE-NODE-SELECTED

hello all...
i have a tree and i wanna when i click on the node another forms open due to form name
i have table includes form_if,form_name " as in H.D.D"
when i present all nodes and i click on the node the form opened and when i click on other node from the tree
" the last previous selected node also opened and when i close it the new form is opened and so on"
the code in when-tree-node-selected is
DECLARE
node_value varchar2 (100);
frm_name varchar2 (100);
path varchar2 (100);
BEGIN
node_value := ftree.get_tree_node_property('block33.sub_TREE',:SYSTEM.TRIGGER_NODE, FTREE.NODE_VALUE);
select FRM_NAME into frm_name
from forms_list
where FO_ID = node_value
path :=(frm_name||'.fmx');
call_form(path);
path:=null;
frm_name:=null;
EXCEPTION
WHEN NO_DATA_FOUND THEN NULL;
END;

Hi,

Fires when a node is selected or deselected.
So your code is getting executed for selection and deselection
use SYSTEM.TRIGGER_NODE_SELECTED to check
IF SYSTEM.TRIGGER_NODE_SELECTED THENRegards

hi all
i have a table that name is:

A Sub query like this can only return one column, not serveral like here with the star *. Replace the star by one column Name that you want to query.
