and have folowing code
DECLARE
htree ITEM;
rg_data RECORDGROUP;
BEGIN
-- Find the tree itself.
htree := Find_Item('tree1');
-- Find the record group.
rg_data := FIND_GROUP('RG1');
-- Add the new node at the top level and children.
Ftree.Add_Tree_Data(htree,
Ftree.ROOT_NODE,

........when i run above code i dont get any error..but it doesnot display anything...
and in the status bar i get following msg...

so what is the way if i want to populate the tree with recordgroup....

You need 5 columns. I could write them out again here or you could look at your other thread on the same subject. You don't need a new thread each day.

How to use template or fragment in PDF form

Hi Expert,
As required by project, I want to create a sample form only with company logo in header and address info in footer. Then this sample form can be made as a template. Any new form development will use this template form, no need to maintain logo and footer one by one.
above is my requirement. In transaction SFP, I can see Tools->Template manager->add template. I tried to save my sample form as a template, but when preview it, no displaying but with error saying "not well format".
Can anyone help me? I just want to create and use a custom template or fagment (it is said Fragment can also reuse to meet my requirement. but I also don't know how to use fragment).

Hi
I'm also starting with hierachical tree (HTree) and I got an example from any Oracle examples or whatever. It works with the 'hr' schema (employee, manager, department).
In the case that I'm not finding any tutorial about htree, I'm taking this one as an example to build my own htree. If you are interested, I can email the example to you.

Validation unit

I have a form module that the form module property validation unit is set to FORM. However, I want to do an immediate validation on some of the items. When_validate_item trigger does not fire on this items. Your help will be appreciated.

Thanks for your prompt response, I thought of doing this but the requirement does not want each item to be validated. Moreover, one items is based on hierachical tree (Htree) and there is go block in when_mouse_double_clicked trigger and when I set the validation unit to default or Item, this trigger did not work because of the Go_BLOCK command

Datatypes and names of columns of recordgroup during run-time

Hi everyone,
Can you please tell me that Is it possible to get the datatype and name of columns of a recordgroup during run-time or not. So that I don't waste my time in searching for this solution. If you are not getting my question then please let me know but I need this help very badly.
Thanks

After the call of the methods GET_COLUMN_WIDTH or GET_ROW_HEIGHT
You need to add this command :
CALL METHOD cl_gui_cfw=>flush.
This will send back from the SAPGUI to your ABAP program the new values.
Found in this Thread : Method GET_ROW_HEIGHT

How do drag and drop in htree?

i would like to drag and drop node in tree look like Object Navigator in
Oracle Form Developer 6i.

Hi jimbo7,
Is this through the Google Calendar web interface, or are you subscribed to the calendar in the Calendar application?
If it is the webpage, I have recently released an application that may help. Multi Event Filter is designed to take dates as text from any source (text of email, CSV or spreadsheet, webpage, text file) and quickly and easily creates events in Calendar. The application is $2.99 to buy on Apple's Mac App Store. You can see more information about it on my website.
On the other hand, if you are subscribing to the calendar in Calendar you should be able to copy the event in Calendar, change the active calendar to the one you want the event in and paste.
Best wishes

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

How to get datatype and label of columns in a record group

Hi all,
I need to create a generic block which displays data of any query. For this, I was thinking at runtime I'll create a recordgroup. For this I was hoping to get the datatypes and label of various columns in the records.
Please help me in this regard
Thanks

How are listbox and radiobutton items working in oracle forms?!?

Hi all.
I need some help over may be a standard case in every real project.
Imagine i have a db table PERSONS -> PERSONID, NAME, TOWNID, MATRIALSTATUSID
and table TOWNS -> TOWNID, TOWNNAME
and table MATRIALSTATUS -> MATRIALSTATUSID, NAME
And i have a standard oracle form with text item person name, listbox item with many towns (from TOWNS table) and the town of the concrete person is selected when the form is inited, after that we can change it by selecting other town and saving it to db.
The same is with matrial status but lets make it as radio group with 3 buttons married, not merried, divorced.
So my questions is how to populate the listbox(radiogroup) for 1 person by selecting data from other preferenced tables. And most important how this data is populated in the list box for example i.e. every town name is indexed in some way or what. I am a java developer and for example in java the control listbox item has two attributes the name(string) that is displayed in the listbox and a index binded for that name, and i work with indexes and show strings. I read about LOV but couldn't understand how to "index" the populated values. Is it possible.
And please can you give me some example of how to load (populate + set current town), change and (if it is possible) "index". The same case appears to be valid with radio buttons and check boxes.
You could give me some tutorials too, i cant find simple and focused on the problem examples.
Thank you.
Best Regards.

Hi,
well here is what i done for now.
First I created recordGroup with query SELECT GENDER, GENDERID FROM GENDERS (I want to select all genders and place them in listbox)
After that i created Listbox and on triger when-new-form i placed this code:
DECLARE
it ITEM:=FIND_ITEM('PERSONS_DETAILS.GENDER');
BEGIN
CLEAR_LIST(it);
POPULATE_LIST(it, 'RG_LIST');
DEFAULT_VALUE(NULL, 'GLOBAL.PERSONID');
IF :GLOBAL.PERSONID IS NOT NULL THEN
SET_BLOCK_PROPERTY('PERSONS_DETAILS', ONETIME_WHERE, 'PERSONID=' || :GLOBAL.PERSONID);
GO_BLOCK('PERSONS_DETAILS');
EXECUTE_QUERY;
:GLOBAL.PERSONID:=NULL;
END IF;
END;
Imagine i have a main form PERSONS that displays general information about many persons (the data is retrieved from PERSONS db table). The form PERSONS displays PERSONID, PERSON FIRSTNAME and PERSON LASTNAME. When a user double click on some row from the PERSONS FORM( i have tabular datablock that displays the person data) other form 'PERSONS_DETAILS' must be displayed with detailed information about the selected person. The data about the selected person is loaded well but i want gender to be listbox and the user can change it if he wants. So i have TABLE GENDERS 1:N with PERSONS and the table has GENDERID AND GENDER. When the user double clicks on single person i must populate the list with all possible genders from the GENDERS table and set the gender of the selected person. How to do that?
P.S.: The example with gender is not very good because it could be only male female, but don't worry about it. You may think about gender list as townlist :)
It finds me the GENDER LIST and populates it. After that i take the personId (that is global variable and comes from previous form) and displays all the data for the person with id personid.
When i compile the form it gives me :
FRM-30351: No list elements defined for list item.
List GENDER

Problems with Listobject based on a recordgroup

Hi all,
I have three problems with a Listobject (popup-_list) showing the records of a recordgroup.
The recordgrroup is created programatically in the WHEN_NEW_FORM_INSTANCE-Trigger of the form. It shall be the source of a ListObject. The values of the recordGrpoup and therfore also of the Listobject depends on the values of an master-datablock. Changing the values of the masterblock, the recordgroup must be requeried and the listobject must be repopulated.
1. When opening the form, the masterblock is empty. Same I want to have the listObject empty. An empty recordGroup seems not to be applied to the ListObject. Is there any possibility?
2. My sql-statement of the recordgroup works with a global variable like so:
:global.grpartid := '1004';
group_id := create_group_from_query
('grpLagorte', 'SELECT evm_a_lagort.bez, evm_a_lagort.lagort_id from evm.evm_a_lagort, evm.evm_n2m_artikel_lagort where EVM_n2m_artikel_lagort.H_MANDANT = m.EVM_A_lagort.H_MANDANT AND evm.EVM_n2m_artikel_lagort.lagort_ID = evm.EVM_A_lagort.lagort_ID and evm.evm_n2m_artikel_lagort.artikel_id = ''' ||:global.grpartid||'''');
I would prefer to replace the global variable with an item from my master datablock, but that seems not to work.
3. I have to requery the group and repopulate the list when changing the master-data.
declare
status                NUMBER;
     list_item          item := find_item('evm_jn_a_l.lst_lagort');
begin
:global.grpartid := :evm_a_artikel.artikel_id;
status := populate_group('grpLagorte');
message ('Status: ' || status);
message ('artikel_id: ' || :evm_a_artikel.artikel_id);
message ('Global: ' || :global.grpartid);
if status = 0 then
     populate_list(list_item, 'grpLagorte');
else
     message('Fehler bei Abfrage der Datensatzgruppe');
end if;
end;
The messages show the right values
status = 0
artikel_id = the choosen next one
global.grpartid = the next artikel_id
The content of the Listobjet does not change.
Its a problem of the recordgroup (How can I figure that out?) or its a problem of the listObject or anything else?
Help would be very appreciated and the problem is a bit urgent.
Thanks
Silke

Silke,
I may not have the answer to all of your questions.
1. If you do a clear_list on the list item and, prior to this, assign it a null value. Does this work, assuming you didn't set the "other" property ?
2. What if you do
_artikelId varchar2(100);
_artikelId:= :block.item;
group_id := create_group_from_query
('grpLagorte', 'SELECT evm_a_lagort.bez, evm_a_lagort.lagort_id from evm.evm_a_lagort, evm.evm_n2m_artikel_lagort where EVM_n2m_artikel_lagort.H_MANDANT = m.EVM_A_lagort.H_MANDANT AND evm.EVM_n2m_artikel_lagort.lagort_ID = evm.EVM_A_lagort.lagort_ID and evm.evm_n2m_artikel_lagort.artikel_id = ''' ||_artikelId||'''');
You should be able to do the same using global variables, in case you need it to be global
3. I don't see whats wrong with the list, maybe you can try to do a clear_list before repopulating it. If this doesn't help try the "magic bullet" and call
synchronize;
after populating the list. I checked if there is a bug filed on this issue for Forms 6i (I remember that you are using Forms 6i) but there is none. So the component should be fine.

How to create button programmatically and assign trigger for it and add code

is that possible ?
How can I create item a button for example programmatically (at run time)
and create trigger (when-button-pressed) programmatically and write a code
in the trigger body as well programmatically.
thankx

Hello David
I used the way list and go button which is more safer than creating buttons because
you can populate the list on fly.

Htree-Value of the parent's selected node

Hi all!
I have an htree in oracle forms10g and I would like to have the value of the parent selected node. There is a function to trap the value of the selected node but I also need the parent's value too.
My tree is structured like this
company--> department--> service-->service_status.
the service_status can be active or no_active. If I click on let's say "active"
I would like to have all the records where service_status is equal to "active" for the service located above the "active" selected

I would like to have all the records where service_status is equal to "active"
for the service located above the "active" selectedI'm not sure what you mean by that, but try "ftree.get_tree_node_parent(my_tree, my_node);" for getting the parent.

Find a specific record in a recordgroup

I am building a recordgroup at runtime of IDNum and Name. (Basically key-value pairs)
I'm able to build the recordgroup. But how do I find a specific record to get a Name value if I have an IDNum?
I know I can just do this with a temp table, but I was trying to do it this way....

Hello,
Use the Get_Group_Record_Number() to retrieve the desired row in the record group (see the on-line documentation).
