How to hide a field based on the value of a field in a different subform - null check doesn't work!

I'm using Javascript to set the actions. I need to hide a text field if the value of a field in another sub-form is null.
- tried checking the value of the other field for null - doesn't work
- tried setting a variable str2 where I know the value of the other field is available then checking that variable when I initialize the text field - doesn't work
What am I missing?

Hi.
Try this in the originating sub form referring to the text field (X).
if (this.rawValue = 1)
X.presence = "visible";
else if (this.rawValue = null)
X.presence = "hidden";

How to Visible/Hide an Item based on the value of another Item

Hi
I need to visible and hide a textitem based on the value of another item.This form has 3 blocks, and the both item is in the first Master Block.
My code is:
if :RECORDTYPE=7 then
     Set_Item_Property('BLOCK.ITEM',VISIBLE,PROPERTY_TRUE);
     Set_Item_Property('BLOCK.ITEM',ENABLED,PROPERTY_TRUE);
ELSE
     Set_Item_Property('BLOCK.ITEM',VISIBLE,PROPERTY_FALSE);
Set_Item_Property('BLOCK.ITEM',ENABLED,PROPERTY_FALSE);
:BLOCK.ITEM:=NULL;
end if;
I wrote the code in the Validate Trigger, but not working when moving Next Record & Previous Record
Thanks in advance

Read the 'Propagation of Property Changes' section towards the end of the page for Set_Item_Property in the online help. I'm not sure what you mean by locking automatically but perhaps it's because of this.
You should also ensure the item you're setting to invisible is not the current item (check :system.cursor_item and go to a different item if necessary).

F4 help based on the Value in other field

Hello
I have a requirement in which there are two fields say field1 and field 2 in an ALV grid (in which new data can be entered). The F4 help of field 2 should be based on the value the user enters on field1.I have checked out the BC_ALV* programs but there are no clear help .
I have tried setting the parameter id of the first field value and then get that parameter id on_f4 event of the second field.But where can i set the parameter id of the first field . on_f4 of first field does not have its value and there is no event after_f4 . There is a parameter e_afterf4 in data change event but to tirgger that there shud be some event right.
Moreover If at all i get the first field value , i can use FM F4_int_table_value_request to show the refined f4 in field 2 . But I am passing the a field symbol table in my grids set table for first display . what can i pass as parameters here to the FM F4_int_table_value_request?

Sorting an ArrayList based on the value of a field in one of the objects.

Hi,
I have the following problem:
A server app returns an array list of simple objects with a bunch of fields.
One of these fields is an int.
How do I go about sorting the list based on the size of the int?
Thanks in advance!

Thanks a lot.
The Comparator solution is actually ridiculously simple.....
public class MyComparator implements Comparator {
public int compare(Object o1, Object o2) {
     if (Integer.parseInt(((ZMData)o1).getAantalposts())>Integer.parseInt(((ZMData)o2).getAantalposts())) {

Can we change the data type of a field based on the value of the field

HI Gurus,
My Requirement is as below -- Could you please guide me
in the Printable Adobe form -- for ex - as usual for dates fields in the Object Pallette the object type is a date/time field and for quantity/currency fields corresponding fields are taken
now in case the either the date, quantity or currency is initial in place of displaying 0.00 or empty date we need to display N/A (Not Applicable)
for this I would like to change the data type of the field
to put it simply --
we need to change the data type of date field from DATE&TIME to Char type to hold N/A or Quantity field to Char field to hold N/A
how can we realize this in SAP adobe forms
Thanks in Advace
Ramchander Rao.K

Hello Ramchander,
     You cannot change the data type of the field at run time in Adobe forms because the type of field you choose at the time of design level is associated with the data type itself.
If you want to achieve your requirement, then your main idea should be to set the data type as CHARACTER itself while designing the field in the adobe form itself. CHAR field will comfortably hold the value of Calculation/amount field, Currency field, Amount, Date, Time HHMMSS, Unit Accuracy, Currency key, Floating point number, Numeric text, Client, Language and many other data types.
After designing the field as TEXT field in Adobe form you have two options.
Option 1:
Select the Date field initially as type TEXT field or CHAR field in Adobe forms.
Suppose the name of the field is TEXTFIELD1, then write the Javascript code on this field in Initialize event as below.
if ( this.rawvalue == null )
     this.rawvalue = "N/A";
If the field is not blank, then it will show the date. Else it will show "N/A".
Option 2:
Select the Date field initially as type TEXT field or CHAR field in Adobe forms. Do the formatting part in ABAP itself. It will increase the performance. Avoid Javascript as much as possible.
Suppose you have a DATE variable l_dats of type DATS. Then take another variable l_date of type CHAR. Then write the below ABAP code.
MOVE l_dats TO l_date.
IF l_date IS INITIAL.
     l_date = 'N/A'.
ENDIF.
Bind the l_date to the TEXT field in the form.
Even in this case, if the field is not blank, then it will show the date. Else it will show "N/A".
But I will suggest you to use Option 2 of keeping the AMOUNT, QUANTITY, DATE, TIME fields etc as CHAR or TEXT fields in Adobe form and do the required formatting in ABAP itself.

How do I remove an icon from the dock of an iMac 10.9.5.? Dragging doesn't work although I have tried a number of different places. I recall right clicking used to give me a remove option.

How do I remove an icon from the dock of an iMac Maverick, 10.9.5? I've tried dragging different places: desktop, finder list etc. No luck.

Drag up towards the centre of the screen & hold for a second or so. The icon will have the 'smoke cloud' appear, let go & it will be removed.
There should also be a 'Remove from Dock' option in the popup menu. It is in the 'Options' section . ctrl+click will 'right click' if right clicking is disabled.
If this is not possible the Dock is locked (this may happen on a 'Managed Mac' normally setup by a company or school etc). See your tech support in this case.

Filter data based on the value of sorce field in mapping

Hi,
I have a scenario (IDOC to file) where i have to move data to target file, only when one of the source fields has particuler value. Otherwise skip the record, no need to write into output file.
Please let me know how to handle it in mapping, without BPM.

Karthik,
Ofcourse there is no need of BPM, You can use the IF without Else function in your mapping with using Equals function.
Example:
Field1 ---> Equals (Particualr Value) -
> IF -
> Then -
> pass it to Target field.
Since there is no Else option, therefore whenever condition will fail, nothing will be passed to the target field.

Populate one text field on a form based on the value in another

I am new to APEX and building my first application.
When a user enters a value in one field, I would like to run a SQL command and then display a value in another field based on the value in the first field. For instance, if a user enters a part number in one field, when they tab off of the field, I would like to display the name of the part in the part name field.
Thanks

Thanks. That put me on the right track. I used that link to find the link http://htmldb.oracle.com/pls/otn/f?p=11933:11:2890374750690437 and then using the two was able to put together a solution.
I am down to one last issue. I am able to return the name back from the process and display it with an alert statement. Unfortunately, I am unable to display the value on the form.
I am doing the following.
<script language="JavaScript1.1" type="text/javascript">
function f_getCustomerName(id)
var v_id = id;
var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=getCustomerName',$v('pFlowStepId'));
get.addParam('x01',$v('P2_CUSTOMER_ID'));
gReturn = get.get();
get = null;
gReturn = (!gReturn)?'null':gReturn;
/* The below do not work
$s('P2_CUSTOMER_NAME',gReturn);
document.getElementById('P2_CUSTOMER_NAME').value = gReturn;
document.getElementById('P2_CUSTOMER_NAME').value = 'TEST';
alert(document.getElementById('P2_CUSTOMER_NAME').value );
alert(gReturn);
//-->
</script>
Process: getCustomerName
declare
l_customer_id customer.customer_id%type;
l_customer_name customer.customer_name%type;
begin
l_customer_id := to_number(wwv_flow.g_x01);
select customer_name
into l_customer_name
from customer
where customer_id = l_customer_id;

Populate text field based on the lov selected value

Hi,
based on the value selected in lov, i want to populate another text field. Below is the code I have written
In PFR:
if(pageContext.isLovEvent())
String lovInputSourceId = pageContext.getParameter(SOURCE_PARAM);
if ("lovCategory".equals(lovInputSourceId))
java.util.Hashtable lovResults = pageContext.getLovResultsFromSession(lovInputSourceId);
if(lovResults!=null)
String value =(String)lovResults.get("lovCategory");
amobj.categorycode(value);
AMImpl code:
public void categorycode(String code) {
sundryCodeVOImpl vobj = getsundryCodeVO1();
vobj.setWhereClause( "lookup_code = "+"'"+code+"'");
vobj.reset();
vobj.executeQuery();
String desc = vobj.first().getAttribute("Description").toString();
String attr = vobj.first().getAttribute("Attribute1").toString();
testEOViewImpl vobj1 = gettestEOView1();
vobj1.getCurrentRow().setAttribute("CodeDescription",desc);
vobj1.getCurrentRow().setAttribute("PurchasingCategoryCd",attr);
vobj1.executeQuery();
With this code, the updated values for the attributes CodeDescription, PurchasingCategoryCd are getting inserted into the database table but they are now showing up in the text fields when a value is selected in lov.
Please tell me what is the mistake I'm doing.
Thanks
Sunny

I'm using Lov Map to populate the lov field say field A. But I need to populate another field say field B based on the value selected in field A.
to give an example of my requirement. Consider a view object having attributes col1,col2,col3 and having following data.
col1--col2--col3
1-----a-------x
2-----b------y
3-----c------z
I 'll populate the lov of field A with values in col1. when user selects value 1 in field A. automatically field B should show value 'a'. If user selects value 2 in field A, field B should show value 'b' so on.
Thanks

Plot a chart dynamically based on the values selected

Hi All,
I have some requirement like this i want to plot a chart . The chart should change dynamically based on target_name and date. What type of UI should I use ? I tried using multiselect or shuttle for choosing the target_name and date picker tool for date once i choose all this the chart should appear. Can I have a custom button called submit so once all the values are entered it plots chart ? Please help me out with our ideas.
Thanks in Advance

Hi,
Using the dependent value sets you can govern the values which can be selected based on a specific value selected in a particular segment. Example if Country name is selected in segment 1 then specific states names as per the country selected can be displayed in segment 2.
As per the requirement described you want to enable different fields based on the value selected in segment1, currently there is no standard mechanism available to enable/disable fields based on a value and you will have to do an extension/customization to meet this requirement.
Thanks,
Sanjay

Setting the Link Group Name in Deep Link based on the value of a column

Using Jdeveloper 11g, Jheadstart 11g
Is it possible to override the link group name in deep linking. For example can I conditionally set that field based on the value of the item.

Edited by: aliegeh on Jul 25, 2010 8:43 AM

Thanks for the suggestion.
Here is what I am trying to do:
I have a table with one visible column that has the following entries:
1. Create
2. Modify
3. Verify
4. Approve
5. View
If the user clicks on row 1 (Create) then the link group name should be "CreateEmployees" to create new employees
If the user clicks on row 3 (Verify) then the link group name should be "MaintainEmployees" for verification and so on.
(This is role based and each role will have access to one or more of the rows in the tabler)
It basically mimics a work-flow type of scenario.
I tried to modify the template and looked at the line:
action="$JHS.facesConfigGenerator.addItemGroupLinkTaskFlowCall((${JHS.Current.item})}" but got stuck there.
Is there a way to change "JSH.current.item" in the template to read the group link name from another column say by using #if statements.
One way I also tried was to introduce a column for each action such as CreateAction, VerifyAction etc which kind of agrees with your suggestion but the drawback is the need to modify the table if another task is required.

Fields required based on a value in another field

Hi,
I am looking to have fields required (Annual Revenues and # of Employees) based on the value of another field (Ownership). Basically, if the value is Public the user is required to enter the Annual Revenue and Employees fields. I thought about using dynamic layouts but the only key field for Accounts is Account Type.
Thanks,
Caryn

Hi Caryn!
I think it is not possible for making #Employees and Revenues required depending on Ownership(as it is a look up field).. it should be possible if you want to do it on any other criteria other than ownership by just renaming the Account Type, Disable all the values of Account Tyope add new values to Pick List and make it driving picklist upon your requirements..
If you require Account Type, create a custom picklist "Account-Type" and add the values.

How to enable/disable the input fields based on the data entered/user action in the web dynpro abap?

How to enable/disable the input fields based on the data entered in the web dynpro application abap? If the user enters data in one input field then only the next input field should be enabled else it should be in disabled state. Please guide.

Hi,

After that Go to the Action ENTER.
First read the input field ( first input field, which is value entered field) , next give a condition
if input value is not initial then set the readonly value is ' '.
