Passing Values to Child Forms
I have a parent summary form. When the user presses a button, it pops up a detail form for the user to edit/fill in. How do I pass the initial values from the parent form to the child form and back? Where can I find an example of this?

Thank you.
Do you happen to know of any tutorials/examples showing various methods of passing values between forms?The same way you pass values anywhere else. When you create your child form, give it a reference to the parent form or references to the data that will be changed. If you feel like making your code more modular, create a class specifically to hold the entered data and be passed anywhere you need.An application context, in effect

Pass Values to Edit Form thru Query String and Save in List
I have developed a custom Edit form from SharePoint Designer and I am passing values thru Query String as below;
http://<>/cli/acc/Lists/GIInfo/testEdit.aspx?ID=262&com=POD_Send
And, user supposed to save the form directly without changing the values came thru Query String as below.
Now, issue is, when user saves the form, values is not getting saved. It saves when we change the value in text box or when we do a text change event in form. Becasue data binding says Text Change even in data binding property.
__designer:bind="{ddwrt:DataBind('u',concat('ff22',$Pos),'Text','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Actions')}"/>
Kindly guide me what is the issue, or correct approach to do that? I want to pass values to Edit Form thru Query string and save in List without changing those.

The issue was resolved by changing the textbox values,
<asp:TextBox runat="server" id="ff1{$Pos}" Name="Title" Text="" Value="{$Destination}" __designer:bind="{ddwrt:DataBind('i',concat('ff1',$Pos),'Text','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}">

Hi Guys!
My Problem is to pass values through call forms to another form. There are two ways I had done it before. First:global variables.
Second library spec with variables in in, then call forms share library data and the calles form uses the same library. The second way is descriped by Oracle Corp., too.
Do you know another, better way, or do I have to make one of this better? What's the best way? Thank you very muchYou can build and pass a parameter list. Look at the help for CALL_FORM for details (I think you'll see an example there of how to use it).

How to pass value between two forms.
Hi all,
how to pass value between two forms(using :parameter),...
Thanks
RajeshTo use parameters, create a parameterlist with the named parameters
DECLARE
pl_id PARAMLIST;
pl_name VARCHAR2(10) := 'tempdata';
BEGIN
pl_id := Get_Parameter_List(pl_name);
IF not Id_Null(pl_id) THEN
DESTROY_PARAMETER_LIST(pl_id);
END IF;
pl_id := Create_Parameter_List(pl_name);
ADD_PARAMETER (pl_id,'MYPARAMETER',TEXT_PARAMETER,:BLOCK.VALUE);
CALL_FORM('MYNEWFORM', NO_HIDE, DO_REPLACE, NO_QUERY_ONLY, pl_id);
END;In the new form you can then just access the parameters via :PARAMETER.MYPARAMETER;
An alternative is the usage of globals:
:GLOBAL.MYPARAM:=:BLOCK.VALUE;
-- call the emp-form
CALL_FORM('MYNEWFORM', NO_HIDE, DO_REPLACE);and in the new form use:
DEFAULT_VALUE(NULL, 'GLOBAL.MYPARAM');
IF :GLOBAL.MYPARAM IS NOT NULL THEN
...The advantage of gloabls is that they can also return values back to the calling form, which is not possible using parameters -
Passing values to sub-forms (Varaible scoping)
I have a "parent" form that calls one of 6 subforms. I'm trying to figure out how to pass values derived in the parent to a sub form.
I am running IdM 8.1.0.9 in glassfish 2.1.1. I set up these test forms to work through this:
my Parent Form:
<Form name='parent' objectLocationID='objectType=UserForm&objectName=parent&objectPath=0&isBegin=true'>
<Display class='EditForm'/>
<Include>
<ObjectRef id='#ID#UserForm:child1' type='UserForm' name='child1'/>
</Include>
<!-- This value needed in child 1 form -->
<defvar name='myvalue'>
<s>test123</s>
</defvar>
<Field name='myfield'>
<Expansion>
<ref>myvalue</ref>
</Expansion>
</Field>
<!-- My attempt at using <Variable>, IdM doesn't like this
<Variable name='myextvar' external='true'>
<ref>myvalue</ref>
</Variable>
-->
<FormRef name='child1'/>
</Form>
my Child1 Form:
<Form name='child1' objectLocationID='objectType=UserForm&objectName=child1&objectPath=0&isBegin=true'>
<Display class='EditForm'/>
<!--
<Include>
<ObjectRef type='UserForm' id='#ID#UserForm:parent' name='parent'/>
</Include>
-->
<Field name='subtext'>
<Display class='Text'>
<Property name='title'>
<concat>
<s>pre1:</s>
<!--
<FieldRef objectLocationID='objectType=UserForm&objectName=marty&objectPath=0&isBegin=true' name='myvalue'/>
-->
<ref>myvalue</ref>
<s>:1post</s>
</concat>
</Property>
</Display>
</Field>
</Form>I was hoping that child forms would share the scope of the parent, and I could just use a <ref> tag in the child form, but that doesn't seem to work. So I started looking at FieldRef/FormRef but I'm not sure they are the right answer either.
When the include in the child form is uncommented, I get :
An unrecoverable error has occurred processing the request. Contact your system administrator.
Syslog ID = LG-0405-115539.
I'm guessing that this is because I include a form that includes this form, and created an endless include loop?
When the FieldRef is uncommented, I get this error:
Attruibute "objectLocationID" must be declared for element type "FieldRef".
The <Variable> tag (defined as external) looks promising, but I haven't run across a good example of how to use it.
When I try to add a <Variable> to my parent form, I get the error: Content of element type "Form" must match...
This doc: http://docs.sun.com/app/docs/doc/820-5821/bvaex?a=view
says that <Variable> is a valid form element, but IdM disagrees.
Any suggestions on how to achieve the passing of values from one for to another would be greatly appreciated.

Edited by: mk152556 on Apr 5, 2010 6:27 AMAn advice I usually follow: Skip defvars and variables, and stick to fields, hidden, not using any Display class that is, if you just need to use the field as an variable. Field are a lot more practical IMHO.

Passing values from a FORM to another FORM
Hi,
I have to pass values from FORM "A" to FORM "B". What is the best way to do this?\
Can I use a GLOBAL variable?
Thanks,
Marc.I think he meant the global namespace.
You set a :global_your_name_here to a value and that value is available in your entire application. See the help file section on the global namespace for more information.
Forms parameters are parameters that you form picks up from the outside when it starts. The calling entity must supply them in the URL or they will be set to null. You set them up in the object navigator in the Parameters node. -
Passing values from a form to a page containing forms.
I would like to pass a value from a form to a page containing two forms (one of the forms is in a tab).Once the value is passed, I want the two forms to be executed with the value passed. Can this be done and how? Any help would be appreciated. Thanks.
Yes, this is possible.
I will give you a brief outline.
From the 1st form, you need to save the value, you want to pass to the 2 other forms, using the wwsto_api_session apis.
Then, using go() or call() from the Successful submission section, you need to go/call the page containing the 2 forms.
You need to write some pl/sql code in the 2 forms (on the page) to retrieve the value saved and perform the action you desire. The saved value can be retrieved using the wwsto_api_session apis.
However, both forms will not get executed at the same time unless both of them are in the same tab i.e. unless both forms are visible at the same time.
If the forms are on different tabs, they will get executed when they are being displayed.
But, there are ways to execute both the forms, if it really necessary, even if they are not on the same tab.
I will be posting the an example soon in this thread. -
Passing value from Portal Form as parameter to portal report
I have a portal form that I have created using the custom form layout editor to build/modify the display of the form. When I run the form and I have a record queried I would like to be able to click a link and pass the value of a field as a parameter to a portal report. For example, lets say I have a field on my portal form called assignment_id, and after I query a record assignment_id equals 1. I would like to use the value 1 from assignment_id as a parameter to a portal report. I am not sure how to reference the value of a form field, can this be done within the header, body or footer of the custom layout editor? Or can I somehow reference the value of a form field from the Additional PL/SQL Code section?
Has anyone tried this with success? Any info is appreciated.
Regards
MarkHi,
You can get the values of the variables from the session variables. Here is an example which gets the value of the field FLIGHT_NO and passes it on to a report.
While accessing the value of a field you should prefix it with "A_" (A_FLIGHT_NO)
declare
flightno number;
blk varchar2(10) := 'DEFAULT';
begin
flightno := p_session.get_value_as_varchar2(
p_block_name => blk,
p_attribute_name => 'A_FLIGHT_NO');
call('SJDEMO30.report1.show?p_arg_names=flightno&p_arg_values='||flightno);
end;
Thanks,

Passing value to another form with on demand process

I would like to pass a value to another form, but to no avail.

How to pass values from one form to another.
Dear all,
i have a table A i want to double a text item and open another form B. then setting values or adding values in it. i want to close the form and open the form A. the values selected in form B. i want to send to the form A.
please help me.
Muhammad NadeemHi
To send value to the form A from B, you do this action.
1. Declare a parameter list:
pl_id paramlist;
2. Create the parameter list:
pl_id := create_parameter_list('ParameterLilst_FormA');
3. Add all value to the parameter list.
add_parameter(pl_id, 'variable1', text_parameter, 'valueOfVariable');
4. Open the form B and you send it the parameter list.
open_form('B', activate, session, pl_id);
NOTE: In there form B you might have some parameters having the same name of the variable added to the parameter list:
e.g.: :parameter.variable1 -

The concept what we have observed is When you click on Submit the values were sent to GP. There GP framework takes care of all these. After that when you try to login to Portal and click on GP Inbox and try to open the application, what ever the data that is sent previously will be retrieved.
Due to some reasons like Delegation and other conecpts where GP will not fit we have scrapped GP and got back to workflow. There we have used the concept of Portal Webservice inorder to send the data to R/3 by clicking on Submit button.
We have successfully implemented the Adobe Forms Offline Scenario using Portal Webservice. -

portal30.wwa_app_module.set_target(l_url,'CALL');
end;
The form displays the empolyee information based on the value of empno from the MD form. The url looks like this http://hostname/pls/portal30/scott.emp_rpt.show?l_arg_names=empno&l_arg_values=
so no rows get returned because there is no value, if i fill it in with a empno it works, so i know the report works, it just isnt the get_value isnt grabbing the empno from the MD form.
nullI figured it out, the save button on a MD form, the doSave; clears out the form fields so do a get_value_as will not work b/c there is nothing there, you need to get the value before the doSave; the below code will work.
declare
l_empno number;
l_url varchar(2000);
begin
l_empno := p_session.get_value_as_NUMBER(
p_block_name => 'DETAIL_BLOCK',
p_attribute_name => 'A_EMPNO',
p_index => 1);
doSave;
l_url := 'scott.EMP_RPT.show?'| |
'p_arg_names=empno&p_arg_values='
| | l_empno;
portal30.wwa_app_module.set_target(l_url, 'CALL');
end;
