Change LOV of column in view, based on values of another LOV of column in the same view

Hi,
I am using Jdeveloper 11.1.1.5.
I have a scenario in which I have two columns in the view. column names are:
1- Column A
2- Column B
both the columns have LOV's
LOV in column A contains values as: 1, 2. Now, when I select the value 1 in column A, In the column B, an LOV named ABC should be shown. and when I select value 2 from LOV in column A, LOV named XYZ should be shown in column B.
how can I do that?
thanks in advance (^.^).

Use onchange attribute of the first drop-down. On change, submit the form. On server side, fetch the values for second drop-down based on the value selected for the first drop-down.

Reading Attributes from different context nodes in the same view

Hi,
I have added a new field as part of an enhancement for Trade Promotions. This field is a checkbox and part of the context node TRADE in the view TPMOE/HeaderEOF. This field will be checked or unchecked using a logic in the background.
The logic will be based on an attribute (Fund Plan ID) which is part of another context node FUNDPLAN in the same view.
How can I read the attribute of FUNDPLAN context node in TRADE context node?
A sample code will be quite helpful as I am new to CRM 2007.
Thanks,
Abhishek

Hi Abhishek,
If I understand your question correctly, you would like to access the Fund plan ID (in a different context node) in the getter setter methods of the check box attribute which you have added.
The code snippet mentioend by sudeep works perfectly fine when you are making any checks in the view implementation class. But since you are in the getter setter methods of the context class, this doesnot work as "me" always refers to the class instance in which you are present.
Now in this case what you need to do is :
1) create an attribute <view_controller> in your context class. Here the context is TRADE. The type of this attribute wud be same as the view controller class CL_TPMOE_HEADEREOF0_IMPL
2) Go to the view controller class and redefine the method
DO_VIEW_INIT_ON_ACTIVATION. This method is called only once when the view is loaded for the first time.
3) In this method, put the following code
me->typed_context->(Trade)->[view_controller] = me.
by the above code, you are setting the newly created attribute to the view controller instance.
4) The next step would be, go back to your getter setter methods or what ever it may be, try referring to the Fund plan ID by the code snippet mentioned below
data: lr_entity type ref to cl_crm_bol_entity.
lr_entity ?= me->[view_controller]->typed_context->[the context node in which the fund plan id is present]->get_current().
lv_field_value = lr_entity->get_property_as_String( **pass the field name here ).
This should definitely resolve the problem.
Thanks,
Vinay

You didn't specify your version of Oracle so here are two options. If 10.2 or greater, use XMLTable, else use the ExtractValue option.
-- The WITH simply simulates your existing table that I do not have.
WITH fake_tab AS
(SELECT XMLTYPE('<?xml version="1.0" encoding="ISO-8859-1"?>
<Settings>
<Setting Name="A1" Value="N"/>
<Setting Name="A2" Value="N"/>
<Setting Name="A3" Value="SOMEVALUE"/>
<Setting Name="A4" Value="N"/>
<Setting Name="A5" Value="Y"/>
<Setting Name="A6" Value="N"/>
</Settings>
') tab_col
FROM dual)
-- For 10.2 and higher use this SELECT
SELECT a5
FROM fake_tab,
       XMLTABLE('/Settings'
                PASSING fake_tab.tab_col
                COLUMNS
                a5   VARCHAR2(10) PATH 'Setting[@Name="A5"]/@Value');

Two iterators based on the same view issue

Hi
I'm using jdev11.1.1.2
My requirement is to have a view object as a form on the page (with next, previous, create/delete buttons)
and to have a popup with the same view object as a readonly table (only for taking a look at a table representation of the view)
So we have iterator A , that the form is based on it, and Iterator B that the table is based on it- both iterators based on the same view object.
My problem is that if I popup the table and enter some filter there (my table is filterable) this filter is applied to the form also. I wont these two iterrators not to interfere with one another.
What is the bast way to do that ?
Thanks
a.gruev

Since you have same view object changes in 1 iterrator will also change the other.
You would need 2 view objects to do that.

Problem with embeding the same view in dynamically created view container

Hello Experts,
              I am getiing a dump when i try to embed the same view inside the dynamically created view container of
dynamically created tabs of a tabstrip
The requirement go like this, i have 2 views in which i have have to embed the 2nd view to view1 where i have an empty
tabstrip without tabs. During runtime i create tabs as well as view containers accordingly and then try to embed view2 in tabs.
I have put the below mentioned code in HANDLEIN,
DATA: lref_vcntlr TYPE REF TO if_wd_view_controller,
        lref_comp    TYPE REF TO if_wd_component_usage,
        lv_embed_pos TYPE string.
lref_vcntlr = wd_this->wd_get_api( ).
lv_embed_pos = 'FILE_PERS_EDIT/VC_GENERAL'.
TRY.
      CALL METHOD lref_vcntlr->do_dynamic_navigation
        EXPORTING
          source_window_name        = 'FILE_PERSISTENCE_WND'          " Window
          source_vusage_name        = 'FILE_PERS_EDIT_USAGE_1'       " Source View usage
          source_plug_name          = 'TO_EDIT_LAYOUT'                       " Outbound plug
          target_view_name          = 'PERS_EDIT_LAYOUT'                  " Second view to be embedded
          target_plug_name          = 'IN'                                                  " Second view inboun plug
          target_embedding_position = lv_embed_pos
        RECEIVING
          component_usage           = lref_comp.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_edit_layout_plg( ).
This works fine for the first time.
However onaction tab select i change the embeding position( 'FILE_PERS_EDIT/view container name of different tab') of the view2 an try to embed view2 in a different tab.
At this point i get a dump stating View2 already present in the window 'FILE_PERSISTENCE_WND' of component.
I think, the view2 embediing has to be removed before i add the view2 in a different tab
Kindly let me know how to remove view2 embedding from tab1 before i add a view2 to a different tab or is there any other
means to handle this problem?
Thanks & Best Regards,
Srini.

Hello Srini,
I found a solution to your problem, because I had a similar task.
In WDDOINIT I changed the method do_dynamic_navigation to if_wd_navigation_services_new~prepare_dynamic_navigation:

    l_view_controller_api TYPE REF TO if_wd_view_controller.
l_view_controller_api = wd_this->wd_get_api( ).

      CALL METHOD l_view_controller_api->if_wd_navigation_services_new~prepare_dynamic_navigation
        EXPORTING
          source_window_name        = 'WDW_MAIN'
          source_vusage_name        = 'VW_SUB_USAGE_1'
          source_plug_name          = 'TO_VW_CONTENT'
          target_component_name     = 'ZTEST_DYNAMIC'
          target_view_name          = 'VW_CONTENT'
          target_plug_name          = 'DEFAULT'
          target_embedding_position = 'VW_MAIN/VC_TAB.VW_SUB/TAB1_VC'

    CATCH cx_wd_runtime_repository.

ADF table and ADF form on the same view object

Hi,
As per the ADF demos available on ADF site, I created a jsf page with 2 panels. One panel is an ADF table based on a view object. And the other panel is and ADF form based on the same view object. My requirement is that as I scroll through the records in the ADF table, the ADF Form should dynamically display the details of the record in the ADF table. My understanding is that this should be automatic. However, its not working as expected. What have I missed?

Hi,
Apply PPR for form that displays details.
Like :
<af:table id="t3">
</af:table>
<af:panelFormLayout id="pfl2" partialTriggers="t3">
</af:panelFormLayout >

Problem displaying the output in the same view

hi Gurus,
I have developed an web dynrpo application and have three views, in the first view I am having an input field from which I am calling a BAPI by giving that input field value as input to the BAPI.
Now is it possible to display the output also retrived from the BAPI on the same view.
Thanks and regards
kris

hi LM,
Thanks for your fast response.
I think I was not clear in explaining my problem.
I have a view in which I have an input field which is the input to the BAPI, now on entering the value in the input field I have a submit button, on clicking the BAPI should be executed and also the the output should be displayed on the same view.
Now regarding the mapping both the input and output are in the same context, would that a problem.
And also after getting the output from the BAPI I have to do some validations based on the output from the BAPI and get some message printed on the view.
Please help me in this issue.
Thanks and regards
kris

Join the same view using 2 different conditions, getting error ORA-00918

Hi, I am trying to do a full outer join using the same view with different where conditions. Sample code below. I am getting the error "ORA-00918: column ambiguously defined". I have used as much alias as I can on the select statements but it gives me the same error.
The weird thing is, RIGHT OUTER JOIN and LEFT OUTER JOIN will work fine. Only FULL OUTER gives the error above.
Thanks in advance for your help.

How to use the TableSorter for two tables at the same view?

Hello,
I am using the TableSorter object in order to sort Dynpro tables.
Suppose I have two tables at the same view, is it possible to use it seperatly for both of them?
I assume that at the wdModifyView method I will need to catch the table that the user clicked on, yet I don't have an idea of how to do it...

Hi Roy,
Constructor of TableSorter
public TableSorter(IWDTable table, IWDAction sortAction, Comparator[] comparators)
So, you have to create instance of TableSorter class for each table on the view.

How do I edit a table cell value in the same view?

This is probably just a clarification more than a question, but when looking at the iPhone->Settings->Mail,Contacts,Calenders view. If you select a mail account, you are taken to the account edit view where you can edit your account information.
In this particular example, there is a 4 row grouped table section, with headers like "Name", "Address", "Password" and "Description".
I am trying to duplicate this method of data entry where I don't have the user select the cell and get navigated to a new screen, but rather just pop up the appropriate keyboard, and allow them to edit within the cells within the same view.
Currently, the only implementation that seems to make sense is to add a UITextField to the cell, and when the user selects, it will allow them to duplicate this behavior. It seems like there's an easier way to do this, but just not finding it.
it seems like SetEditing deals more with deleting, adding and reordering...not actually editing data within the cells.
Anyways, if there are any tips/tutorials/etc to look at, much appreciated!

i do that. but the new window doesnt open a folder in the same path location

How to create a new row for a VO based on values from another VO?

Hi, experts.
in jdev 11.1.2.3,
How to create a new row for VO1 based on values from another VO2 in the same page?
and in my use case it's preferable to do this from the UI rather than from business logic layer(EO).
Also I have read Frank Nimphius' following blog,but in his example the source VO and the destination VO are the same.
How-to declaratively create new table rows based on existing row content (20-NOV-2008)
http://www.oracle.com/technetwork/developer-tools/adf/learnmore/13-create-with-params-169140.pdf
I have tried:
1.VO1(id,amount,remark1) and VO2(id,amount,remark2) are based on different EO,but render in same page,
2.Drag and drop a Createwithparams button for VO1(id,amount,remark),
3.add: Create insertinside Createwithparams->Nameddata(amount),
4.set NDName:amount, NDValue:#{bindings.VO2.children.Amount}, NDtype:oracle.jbo.domain.Number.
On running,when press button Createwithparams, cannot create a new row for VO1, and get error msg:
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: For input string: "Amount"
java.lang.NumberFormatException: For input string: "Amount"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
Can anyone give some suggestions?
Thanks in advance.

Hi,CM,
I'm really very appreciated for your quick reply! You know, today is Saturday, it's not a day for everyone at work.
My principal requirement is as follows:
1.select/check some rows from VO2, and for each selection create a new row with some attributes from VO2 as default values for VO1's corresponding attributes, and during this process the user may be cancel/uncheck or redo some of the selections.
--so it's better to implement it in UI rather than in EO.
2.it's better to implement this function with declarative way as in Frank Nimphius' blog.
--little Jave/JS coding, the better. I only have experience in ORACLE FORMS, little experience in JAVA/JS.
In order to get full information for the requirements of my use case, can take a check at:
How to set default value for a VO query bind variable in a jspx page?
(the end half of the thread: I have a more realworld requirement similar to the above requirement is:
Manage bank transactions for clients. and give invoices to clients according to their transaction records. One invoice can contain one or many transactions records. and one transaction records can be split into many invoices.
