Compiling error in Hierarchical Tree !!!!! Urgent attention!!!

I have made the Hierarchical Tree as described in the resuable demo help as is but when ever i try to compile the form i gets error on the navigator."anything!". I guess the forms are not able to find the navigator package. I have attached the navigator.pll. I think there is nothing mroe to attach to a form
Till now i have searched every documentation on the net and the files ships wiht DEV 6.0.5.2. But not ablet o find any thing regarding the installation of navigator package :( Is there any one can tell me how u remover the compiling error from the form which is dur to the navigator package!!!!
null

If you are using DEV 6.0.5.2 you should use the FTREE built-in package. Look under the Built-In package node. The Navigator.pll was a demo used in Forms4.5 before there was a hierarchial tree item type.
Thanks,

is it possible and how can i do this in order to have something like this...

You didn't give quite enough information to approach the question. I am assuming you are using forms since that is the forum you are in. I will also assume that you are using an Oracle database and PL/SQL as the programming language.
One thought would be to implement the tree in a database table where each node is a record. If you didn't need to share the tree among users then you could implement it as a PL/SQL table on either the client side or server side. If the tree needed to be persistent for the duration of the session then you could make it part of package. If it needed to persist beyond the end of the session then a Database table would probably be your best bet.
With each record being a node you could have a field which points to the primary key of the node which is its parent. The root node could be represented by nodes who had parent fields of NULL, zero, 'root' ... This would be simple to maintain. However if searching is not efficient with this model or if programming requirements seem to be cumbersom then you could have each node have a child and sibling field. The parent would point to the first child and then the first child would point to its next sibling. The last sibling would have a NULL pointer.
Hope this was helpfull.

Hierarchical Trees-----------Urgent

Hi All,
Can anyone tell me that while creating a RG for the Trees is it possible to join more then 2 tables.....
Thanks In advance

Please,
Try to keep the word "urgent" out of this forum, that is not a commercial site and is handled by people who just want to help the community without any "contract" obligation.

*** URGENT *** Hierarchical Tree *** URGENT ***

Hi,
following situation:
I have a tree item (ht) in a block TB_FRM_NAME within a help form. This tree is filled with the Module Names within the entire application.
I fill this in the WNFI:
Fpr_Fill_Tree_Item
( 'TB_FRM_NAME.HT' -- pi_tree_item_name
, 'rgp_fwe' -- pi_record_group_name
, 'SELECT b_fu_id , ' -- pi_sql_statement
||'level , '
||'bemerkung, '
||' NULL, '
||' NULL '
||'FROM b_funk '
||'ORDER BY bemerkung
The Content of the forms-procedure is:
PROCEDURE Fpr_Fill_Tree_Item
-- In-Parameter
( pi_tree_item_name IN VARCHAR2
, pi_record_group_name IN VARCHAR2
, pi_sql_statement IN VARCHAR2
) IS
-- Variablendeklaration
v_tree_item Item; -- fÃ¼r das Baumverzeichnis
v_rgp_id RecordGroup;
BEGIN
-- Initialisierung der Variable, Itemname holen
v_tree_item := Find_Item (pi_tree_item_name);
v_rgp_id := Find_Group (pi_record_group_name);
IF NOT Id_Null (v_rgp_id) THEN
-- Record Group existiert bereits, also lÃ¶schen
Delete_Group (pi_record_group_name);
END IF;
-- SQL Statement fÃ¼r die Record Group (Bedeutungen)
-- 1. Element Initial State
-- 2. Element Depth
-- 3. Element Label
-- 4. Element Icon
-- 5. Element Data -- when I enter Column name here
-- filling the tree doesn't work!
v_rgp_id := Create_Group_From_Query
( pi_record_group_name
, pi_sql_statement
-- Wenn die Record Group erstellt werden kann, ...
IF Populate_Group (v_rgp_id) = 0 THEN -- Fehlerlos
-- Record Group mit Tree verknÃ¼pfen
Ftree.Set_Tree_Property
( v_tree_item
, Ftree.Record_Group
, pi_record_group_name
END IF;
END;
After filling I want to add the names of the tab_canvas pages, when the user clicks one of the Modules in the application.
To test this I added following code in the WTNS Trigger:
-- Hier muss die nÃ¤chste Ebene des Baumverzeichnisses gefÃ¼llt werden
DECLARE
v_node Ftree.Node;
v_tree_id Item;
v_tree_level NUMBER;
v_tree_label VARCHAR2 (30);
v_tree_value VARCHAR2 (30);
BEGIN
v_tree_id := Find_Item ('TB_FRM_NAME.HT');
v_tree_value := Ftree.Get_Tree_Node_Property
( v_tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Value
v_tree_label := Ftree.Get_Tree_node_Property
( v_Tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Label
v_tree_level := Ftree.Get_Tree_node_Property
( v_Tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Depth
IF v_tree_level = 1 THEN
v_node := Ftree.Add_Tree_Node
( v_tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Sibling_offset
, Ftree.Next_Node
, Ftree.EXPANDED_NODE
, 'M'
, NULL
, 'M'
v_node := Ftree.Add_Tree_Node
( v_tree_id
, v_node
, Ftree.Parent_Offset
, 1
, Ftree.LEAF_NODE
, 'SUB'
, NULL
, 'SUB'
END IF;
END;
Result of this is, that the newly added node is placed at the first level of the tree. I don't want this! I would like to know what to do, so the newly added node is being shown at the second level.
Result
+-module1
|-module2
|-module3
Then the user clicks on module2 and the result is
+-module1
|-module2
--M
||-SELECT bemerkung FROM b_kat*
|-module3
Desired Result
+-module1
--module2
||-tab_page1
||-tab_page2
||-tab_page3
|-module3
*) Here I want the contents of the column to be displayed and NOT THE select statement.

Hierarchical Tree error - fighting for over a year

For over a year now, our Oracle forms have presented an elusive problem with Hierarchical Trees. First some core information:
We are running Developer 6i, patchset 8, on a Sun host and an Oracle 8i database. Our forms are deployed over the web on the
Oracle Application Server using J-Initiator 1.1.7.27.
Now, only on our Production platform, and only during busy times of the day, we randomly get the error "Invalid Query for Hierarchical
Tree" when one of our tree-based forms populates the tree. This error is sometimes followed by the infamous
FRM-92100 "connection has been terminated" error. This happens whether building the tree with a single Selec and Populate Treet,
or via a systematic series of Add Tree Node calls.
We have tried rebuilding the form logic to eliminate form corruption, (form corruption - happens if you open a large FMB in the
forms developer without first being connected to the database, manifests itself as random and odd form behaviour,
or FRM-92100 errors, Oracle product support denies it really happens), we have added debug code, we've even tried generating
the FMX on the Production platform as part of our deployment (normally we generate FMX files on our Integration platform
which mirrors Production).
We are not scheduled to upgrade for Forms 9i and the 9IAS for several more months, so upgrading isn't an immediate option for us.
Any and all ideas welcome.

Hi Nigel,
Two questions:
1. When the publisher sends the access permission to the subcriber by:
netStream.send("|RtmpSampleAccess", true, true)
, on the subscriber side, what event or function can handle the guaranteed receipt of the access permission? Currently it is possible to draw the incoming stream video upon receiving NetStream.Play.Star and waiting for 5 seconds or so:
public class MyWebcamSubscriber extends WebcamSubscriber {
override protected function layoutCameraStreams():void
// trying the event listener seems to work here.
_streamManager.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
override protected function onNetStatus(e:NetStatusEvent):void
super.onNetStatus(e);
case "NetStream.Play.Start":
setTimeout(function():void {
// draw the video from the incoming stream here.
}, 5000);
The questions is, which event can let the subscriber know that it has the access permission to the video stream?
2. In WebcamPublisher, why is that the access permission is sent 3 times?
a. Once on receiving NetStream.Connect.Success with 0.5 second delay, as in below.
b. Once immediately upon receiving NetStream.Connect.Success, as in below.
protected function onNetStatus(p_evt:NetStatusEvent):void
if (p_evt.info.code=="NetStream.Connect.Success") {
setTimeout(sendSnapShotPermission, 500);
_stream.send("|RtmpSampleAccess", true, true);
protected function sendSnapShotPermission():void
_stream.send("|RtmpSampleAccess", true, true);
c. Once in onConnectionTypeChange() with 2 seconds delay:
protected function onConnectionTypeChange(p_evt:StreamEvent):void
if ( _streamManager.isP2P) {
_stream= new NetStream(_connectSession.sessionInternals.session_internal::connection as NetConnection,NetStream.DIRECT_CONNECTIONS);
setTimeout(sendSnapShotPermission, 2000);

Error 7343 when delete a recordin database and hierarchical tree

I got this error after delete a record and call the procedure to refresh the hierarchical tree.
This is my code:
PROCEDURE LOAD_TREE IS
htree ITEM;
rg_id RecordGroup;
errcode number;
BEGIN
rg_id := find_group('RECORD_GROUP_POPULA_TREE');
errcode := populate_group(rg_id);
-- Find the tree itself.
htree := Find_Item('HIERARCHICAL_TREE.TREE');
-- Populate the tree with data.
Ftree.Set_Tree_Property(htree, Ftree.RECORD_GROUP, rg_id);
END;
I put a code at the trigger KEY-COMMIT to refresh the hierarchical tree always the button F10 is pressed. Look:
begin
commit;
LOAD_TREE;
end;
When I insert records that´s ok...the problem is when I delete records.
Thanks!
Sabrina

I found the solution after read this thread: Hierachical tree delete node
Thanks

Can i have a check box in the hierarchical tree in the icons place, urgent!!! please

Hi,
I'am working on the Hierarchical Tree structure which should have three levels, I need to have a check box in the place of the icon & if i select a node that node & the child nodes should get selected.
After this when i say move selected ( i'am trying to use picklist class also) the entire checked tree has to move to the display area to the right & should display as tree structure & after this if i save then the checked records which are moved to another text area should get saved!!
How to achieve this? I have the tree structure ready but the check box part is the worrying factor! & then moving the checked records to the right using picklist class is the second problem & finally saving records to database.
Any help in this regard will be deeply appreciated:)
If check box is not possible then i will have to look at other methods, will the tree structure allow checkboxes????
Thanks
Mahesh

No the tree will not allow checkboxes

URGENT *** Hierarchical Tree in Forms 9i *** URGENT

Hello everybody,
for my company I need to build a hierarchical tree item, that will display static data over three levels. Let's say: departments, employees and employee projects.
How do I fill the Item?
When do I fill the Item?
Where do I fill the Item?
What are the elements of the SQL query, that fills the hierarchical tree?
Any help will be appreciated
[email protected]

Note:210663.1 helped a bit.
I used the database column as the third element in the select part and put NULL as the fifth element. Then it worked.
Now I am looking for the way to add the employees, when the user selects / activates a department node.

Urgent: Form Compilation Error using frmcmp.sh on OAS 10.1.2, pls help..

Hi All,
I am upgrading from OAS 9.0.4 to 10.1.2 where Forms 10g application is deployed.
When I try to recompile with frmcmp.sh :
frmcmp.sh userid=system/oracle123@odb module_type=FORM module=menu1.fmb
I get errors :
Compiling Procedure GET_PATH...
Compilation error on procedure GET_PATH:
PL/SQL ERROR 201 at line 4, column 32
Identifier 'APPS_MENU1_DET' must be declared
PL/SQL ERROR 0 at line 4, column 3
SQL Statement ignored
Compilation error have occured.
Form not created
What cause this error ?
FYI, on the above compilation I connect to different database/schema, not the one
which is used by the Form, is this the reason of th error ?
During compilation, Do I have to connect to the database/schema I used when develop the form ?
DO I have to create all tables in the schema first before compilation ?
Tnank you for your hwlp,
xtanto
PS. When I compile the same Form with F90genm.sh on OAS 9.0.4, NO ERROR.

From my experience it's a really bad idea to install OCS into a AS IM. When it comes to upgrades and patches you'll pull your hair out!
Why not install OCS first and then install the BI into the OCS AS server... I have not checked the certification matrix but that might be a better solution to look into.

Compile error in hidden module: module starter (Urgent)

Hi Experts,
I am trying to logon to my word document template which was working fine before and now i am getting the error compile error in hidden module: module starter any advise or help can be greatly appreciated. I am using word 2010 and OBIEE version 11.1.1.5
Thanks,
RC

I was getting same error and able to resolve this problem by following below steps. I have windows 7 and office 2007.
1. Uninstall BI Publisher. Check if all BI Publisher files are clean-up from your computer. Look for template file under C:\Users\UserID\AppData\Local\Oracle\BIPublisher\TemplateBuilderforWord and C:\Users\UserID\AppData\Roaming\Microsoft\Word\STARTUP. Recommended cleaning of temp folder under Window directory.
2.     re-install BI publisher.
3.     Rename MSComctlLib.exd file to MSComctlLib.exd_bak from “C:\Users\UserID\AppData\Roaming\Microsoft\Forms” directory. I have windows7, Path will not be same on other OS. Recommend searching for this file.
4.     Restart MS Word, then click on Add-Ins->Oracle BI Publisher->Log On.
Hope this will help.

Help needed for compiling error URGENT

Hello,
I have been looking at this compilation error for a while and I cannot figure it out.
I am compiling with this command:
javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
The error is:
C:\java\hw5>javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
src\pshah3\library\gui\GraphicalGui.java:32: error while writing <anonymous pshah3.library.gui.GraphicalGui$1>:classes\pshah\library\gui\GraphicalGui$1.class
(The system cannot find the path specified)
public void actionPerformed(ActionEvent e) { System.exit
(0); }
Why is it telling me that it cannot find the path, when it has to create the .class file itself?
I would appreciate some insight into this problem?
Thanks,
Premal

Thank you for you help, but i'am still a bit confused. The "pshah" was a typo, it should have been pshah3, so that's not the problem. Here's a more detailed explanation of what i'am trying.
I am declaring the exitlister class in the following path:
c:\java\hw5\src\pshah3\library\gui
The file is fairly simple, it looks like this.
package pshah3.library.gui;
import java.awt.*;
import java.awt.event.*;
public class ExitListener extends WindowAdapter{
     public void windowClosing(WindowEvent event) {
          System.exit(0);
The other file that i'am including is in the same location...it starts out like this.
package pshah3.library.gui;
import pshah3.library.*;
import java.io.*;
import java.util.*;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class GraphicalGui {
          public static void main (String[] args){
          JFrame backGround = new JFrame("Tech Library");
          backGround.setSize(400,150);
          backGround.addWindowListener (new ExitListener());
          Container content = backGround.getContentPane();
I am compiling from the c:\java\hw5 directory with the command
javac -classpath classes -sourcepath src -d classes src\pshah3\library\gui\GraphicalGui.java
I am doing this so all the classes go in a "classes" directory with the same heirarchy as the source.
Do you think i'am doing something funky with the packages??
Again the error is:
src\pshah3\library\gui\GraphicalGui.java:39: error while writing <anonymous pshah3.library.gui.GraphicalGui$1>: classes\pshah3\library\gui\GraphicalGui$1.class
(The system cannot find the path specified)
public void actionPerformed(ActionEvent e) { System.exit
(0); }
THANKS A LOT!!!

Hierarchical tree traversal..!!

Hi all,
I've populated a tree (Hierarchical tree - Ftree in Forms6i). Now I want to traverse it from the root node to the last nodes' last leaf....
How can i achieve this...
Please guide me through...
Very urgent
Thanx in advance...
RK Raju

a control block is one not based on a table/view/procedure . check the block's query data source name. its must be blank.
I suggest you create a procedure where you create the record_group using
CREATE_GROUP_FROM_QUERY,populate_group and ftree.set_tree_property
Here is my code that I i used to populate my tree .it works:
PROCEDURE populate_the_tree IS
grp recordgroup;
error_number number;
grpname varchar2(20) :='rg_group';
tree_id item :=find_item('ctrl.tree');
grp_qry2 varchar2(500) :='select -1,level,ename,null,empno from emp start with mgr is null connect by prior empno=mgr';
begin
     grp := find_group(grpname);
     if not id_null(grp)
          then delete_group(grp);
     end if;
--     grp := create_group_from_query(grpname,grp_qry1||grp_qry2);
     grp := create_group_from_query(grpname,grp_qry2);
     error_number:=populate_group(grpname);
     if error_number <> 0
          then message('Error while populating tree');
          raise form_trigger_failure;
     end if;
     ftree.set_tree_property(tree_id,ftree.record_group,grp);
END;

Newbei tries to create hierarchical tree

hi all;
I'm pretty new to the oracle forms and I'm trying to create a system similar to forum.
I have created the following table at the database;
create table tblFrmData(
frmID number(2), -- forum ID
frmNodeID number(5),
frmParentNodeID number(5), -- the NodeID of the parent branch
frmSubject varchar(100), -- the subject ( will be the label of tree)
frmBody varchar(1000), -- the body of the message (will be the data of the tree)
Now I want to create a tree depending on the data in this table
I have created the tree with dragging and droping from the toolbar at forms. The name is tree8. It is in block3.
I have also created a record group and named it as RG. The select statement used while creating the RG was
select -1, frmNodeID, frmSubject,'', frmBody from tblFrmData
after that I have modified when-new-item-instance trigger of tree8 as following
declare
htree ITEM;
begin
htree:=Find_Item('block3.htree8');
Ftree.Set_Tree_Property(htree, Ftree.RECORD_GROUP, 'rg');
end;
this trigger was compiled without error.
when I save the form and try to run it the following error is given! And I do not know how to solve it although I have readed the referances and looked at the old questions in this forum.
frm-32089: trees must be in single row, single item blocks.
hierarchical tree item TREE8
Block: BLOCK3
Form: FORM_TREE
frm-30085:Unable to adjust form for output
I'm waiting for your answers
regards
erdem seherler

Just ensure that the Hierarchical Tree you have created is the only Item present in that Data Block.
Move all other items to a new Data Block.

Need Simple Hierarchical Tree Example

Can someone e-mail me a simple, working hierarchical tree example, along with what tables i need to insert into the database? Like the car/airplane example, or employee/department example.
I tried following the instructions in the Introduction to Hierarchical Tree example from metalink, but the tree still does not display on my form, even though the data query is valid. Nothing happens when i click the button.
I need this pretty urgently, so any help will be appreciated! Thanks! My e-mail is [email protected]

Thats what i don't understand, you see. There is no query error. I know when there is, because when i type the query wrongly, the error prompts. However, when the query is correct, nothing happens. When i go through in debug mode, it does enter the statement to populate the tree. This is my record group/data query(i tried putting it in both) :
SELECT initial_level
,node_depth
,node_label
,node_icon
,node_data
FROM MyTreeData
START WITH node_parent IS NULL
CONNECT BY node_parent = prior node_data
This is my populate tree code :
DECLARE
     htree ITEM;
     top_node FTREE.NODE;
     find_node FTREE.NODE;
BEGIN
     -- Find the tree itself.
     htree := FIND_ITEM('mytreeblock.mytree');
     -- Populate the tree with data.
     ftree.Populate_Tree(htree);
END;
This is the format of data in the database :
initial_level node_depth node_label node_icon node_data node_parent
-1 2 Car Null CAR TRANSPORT
-1 2 Plane Null PLANE TRANSPORT
0 2 Bike NULL BIKE TRANSPORT
1 1 Transport NULL TRANSPORT
0 3 Honda NULL HONDA CAR
0 3 Boeing 747 NULL 747-400 PLANE
0 3 Mazda NULL MAZDA CAR
I hope its not a problem with my Forms program, so i'm hoping that someone can e-mail me a working one to see. I've been reading up on this for a few days already, but i do not know why its not working.
Thanks for your help again, Kevin! I really appreciate it.

How to go to a particular node in a hierarchical tree?

I want to do this simple thing with a Forms hierarchical tree.
Since tree has lots of levels and branches I want to give a search box.
User types the label and press a button. The form then has to query the tree node and expand ONLY the path where the node is (if found) and highlight it. If a node with a label is NOT found I give an error message to the user.
I got hold of a code segment to explode a tree and modified it, but it does not work. The entire tree is expanded and you don't know where you are.
Any help will be greatly appreciated?
PROCEDURE Expand_All_Nodes_in_Tree IS
     node ftree.node;
     htree ITEM;
     state varchar2(30);
BEGIN
     -- Search the tree identifiant --
     htree := Find_Item('menu.tree');
     -- Search the root --
     node := Ftree.Find_Tree_Node(htree, '');
     -- Expand all nodes --
     WHILE NOT Ftree.ID_NULL(node) LOOP
     state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
     IF state = Ftree.COLLAPSED_NODE THEN
     Ftree.Set_Tree_Node_Property(htree, node, Ftree.NODE_STATE, Ftree.EXPANDED_NODE);
     END IF;
     node := Ftree.Find_Tree_Node(htree, '', ftree.find_NEXT,Ftree.NODE_LABEL,'', node);
IF Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_LABEL) = :ctrl.node_lable_to_search THEN
EXIT;
END IF;
     END LOOP;
END;

Hi Channa,
Try this code with you tree i am using the same situation and this code is working perfect with me.
PROCEDURE find_node_in_tree(search_string varchar2, find_type varchar2) IS
htree ITEM;
search_start_node ftree.node;
find_node ftree.node;
BEGIN
htree := Find_Item('blk_tree.main_tree');
     search_start_node := nvl(ftree.get_tree_selection(htree,1),ftree.root_node);
     find_node := ftree.find_tree_node(htree,upper(search_string)||'%',ftree.find_next,ftree.node_label,ftree.root_node,search_start_node-1);
     if find_node = 0 then
          find_node := 1;
end if;
Ftree.Set_Tree_selection(htree, find_node, Ftree.SELECT_ON);
exception
     when others then
          NULL;
END;
