Hi,
Below steps for Vo extension:
---Copy the package in which that seeded vo exists to your local machine where you have jdeveloper installed.
---Create a new OA Workspace and project.
---Create your Custom package and in that create new View Object with new Query including your new attribute.
Ensure in the extends you select the Seeded VO.
---While creating VO select in extends property standard vo and create tr attribute.
---Double click on your jpx and go to substitution and select seeded VO in available list and Custom VO in Substitute List Click on Add.
---FTP the new package you created to $JAVA_TOP
---Run jpxImport utility for your substitution to take place.
---Bounce apache.
---Through personalisation set read only for Number as i given in SPEL.${oa.seacrhVo1.readonlytr}.
---While you will attach VO to that field ensure View Instance name is your Seeded View Instance name while view Attribute will be your new Attribute added.

Regards,
Rahul.

Yes its possible Qui,
you need to perform following steps:
1. check the codelink property of that particular iview.
2. download the .par file from systemadmin-> support.
3. import in NWDS, and make change in the .jsp or .java file of that iviews component.
4. you need to know which BAPIs to be called for accessing the report, then export the .par file and make a new iview out of that .par file.
5. now you will get that button in your iView.
6. calling the proper backend function/BAPI is your task now.

XML form field should be read only.

Hi All,
Can we have a field in a XML form which is read only and the number in field should be incremented every time a new form is created.
Is this possible.If yes can someone please guide me how.
Thanks,
Nikhil Pai

Hi Nikhil,
Do u want this property to come in the Edit form also, or only on the show form?
If its only on show form,
1. Keep a text file in KM with a starting number say 1000.
2. While creating the XML form, a KM Service listening to resource creation only in the folders,
will update a property and also edit the text file and replace the number by 1001.
So in the show form u will have a unique number for each XML form.

Querying up AR Customer OA page in read-only mode for a Single Customer

We are building a Custom Form in which associated Customer <defined in AR> would be queried up.
Now we want to give an option to the User to view the complete details of the Customer. We would be giving a menu option in Tools 'View Customer' thru which he would see the Full Customer Details. <AR Customer OA page>
We have two requirements
1> The Full Customer Details should show up in Standard OA Customer Page the moment page comes up. The user should not be required to query the details.
2> It should be read-only and user should not be able to update any field.
How can we achieve this requirement? I did some RnD but did not see any place in EBS where we display the Customer Page in read-only mode and that too quried up for one particular customer.
Thanks
Arun

Hi Arun,
Please let me know if find any solution for this. We have a similar scenario in which we need to call the customer Page with all the inforamtion populated, related to one customer.
Thanks in advance,
Mannuru

Read-Only text area

Hi,
I'm using a text area to display a longer read-only text. It should display only 5 lines and, if the text is longer, it should be scrollable. Works fine as long as I set the attribute Editable to true. But if I set it to No (because it should be read-only), I get the following problems:
- It does not show only the 5 lines anymore, but the complete text without scrollbars.
- It shrinks the size of the text area, so that it fits the text inside. You can see that looking at the borders. But I wanted to have the borders at the original size independent of the text.
Does anyone knows, how to solve that?
Thanks&Regards
Matthias

to the best of my knowledge, if you make it read-only you cannot have the scroll bar enabled. and whatever you explained is the expected behaviour!!
But, i have a workaround under three conditions:
1. if you need the scroll bar
2. if you want the size of it as in the initial state - without disturbing the existing size and format of page
3. you wish to retain the value
keep the value of the text area in a temporary object and pass it to the reference attribute on submit of page. (here we are just retaining the value and not making it read-only)
this helps in keeping the format of page undisturbed!!

11.5.10 : Modifying read only property of columns

Hi All,
I am having an advanced table with 4 columns and all of them are editable [value is entered through an LOV].
My requirement is that if user enters value in one column then all other columns should become read only [in that row only].
Can somebody suggest some way out? Should i go for EL or PPR?
A sample code will be of great help.
Regards
Lokesh

Hi,
Please correct if im wrong...
U have impleted 3 lov item in advance table RN lov1,lov2,lov3
if any one selected remaing 2 should moved to read only....
for this
use ppr for this,cretae 3 tr attributes and chnage the read only prpty using SPEL ...
then in CODE.:
if("lov1".equals(pageContext.getParameter(SOURCE_PARAM)) && "lovValidate".equals(pageContext.getParameter(EVENT_PARAM)))
write the code for making remaing 2 lov read only.
else if("lov2".equals(pageContext.getParameter(SOURCE_PARAM)) && "lovValidate".equals(pageContext.getParameter(EVENT_PARAM)))
write the code for making remaing 2 lov read only.

Make Select rows and columns as read only in Table Control

Hi All,
I would like to know how to make certain cells in a Table Control as display only.
Table control should look like-(Those in bold are read only or in display mode)
Name1 Idno1 Address1
Name2 Idno2 Address2
Name3 Idno3 Address3
Name4 Idno4 Address4
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
My table control should display all the above fields the way it is above of which first two colums and 4 rows should be read only,and the rest of the empty rows in the TC should be in change mode.i.e it must have provision to add new rows but not change the first two columns of existing rows.
In short I am looking at solution to hide particular no of rows and columns and not the entire column.

In the PBO of the table control loop. just write these statements
NAME and IDNO considering the fields on the screen.
and WA_TAB is the table work area being passed to the table control to display the rows.
if not WA_TAB-NAME is initial and not WA_TAB-IDNO is initial.
loop at screen.
if screen-name = 'NAME' or
 screen-name = 'IDNO'.
screen-input = 0.
modify screen.
endif.
endloop.
endif.
which means that the fields are disabled only if NAME and IDNO are not initial.

Making Read Only A select List Item

Hi,
I am using Application Express 3.1.1.00.09 version.
If the date field is future date then the Select List field should become Read only.
I tried to make "read only".
When I made it "read only" '>[] is displayed???
Does some one have a solution?
Thanks,
Priyanka.

Hi Leckraj,
I assume that
the select list is not displayed at all.means that your page item is not rendered as a select list input control, but it's rendered as text only, right? That's the nature of the read only condition, it will render almost all controls as text only.
About the dynamic action solution. That can be simplified and doesn't require a hidden item or JavaScript.
1) Create a dynamic action which fires for the "Page Load" event
2) As (Server Side) Condition Type set "exists (SQL quer returns...)" and specify your SQL statement
3) Use a "Disable" action to disable your select list page item
The above dynamic action will only be included and executed on the page, if the SQL statement returns a value.
Note: Please keep in mind that dynamic actions are browser based operations, for a skilled user it's no problem to enable the select list and modify the value. To secure it you should add a server side validation to verify if the user is really allowed to modify the value. That's the difference to the "Read Only Condition", because in that case the APEX engine guarantee that the value can't be modified.

Console Access - Read Only Permissions

How would I go about granting read-only access to a particular set of driver packages and read-write access to others? I understand the concept of security roles and scopes, but I'm not seeing a way to adjust read-only/read-write based on
scope.
Appreciate the help!

The first thing that pops-up in my mind, is two security roles and two security scopes.
Scope 1 is scoped to a few driver packages and role 1 only provides read-access to driver packages. Attach these two to the administrative user/group that should have read-only access.
Scope 2 is scoped to the other driver packages and role 2 provides read-write access to driver packages. Attach these two to the administrative user/group that should have read-write access.

How to make fields read only in acrobat 9?

hi folks

Best practice for making form read-only at certain steps in process?

I have a process with a single form and 4 Assign Task operations. During Assign Task operations 1 and 3, the form is edited. During Assign Task operation 2 and 4, it should be read-only (it is reviewed and acknowledged, but not changed). There is no single criteria in the form data that indicates whether a form should be read-only or not -- this is only signaled by the step in the process. What is the best way to manage the read-only state?
Is there a way to make the form read-only via a setting in Workbench, or should I do this via a script in the form?
Thanks!
Toby

Making Read Only 'Payment Terms' field.

Dear All,
I want to restrict the changes in 'Payment Terms' in a sales order.
It should be read only for the user who is using VA01 & VA02.
Is this possible to do in object level? If so, what is the object i can use for this.?

buddhika

HI,
To make a filed entry enabled or grey (non-entry allowed):
User exits in the program MV45AFZZ-USEREXIT_FIELD_MODIFICATION
This user exit can be used to modify the attributes of the screen fields.
To do this, the screen fields are allocated to so-called modification groups 1 - 4 and can be edited together during a modification in ABAP.
If a field has no field name, it cannot be allocated to a group. The usage of the field groups (modification group 1-4) is as follows:
Modification group 1: Automatic modification with transaction MFAW
Modification group 2: It contains 'LOO' for step loop fields
Modification group 3: For modifications which depend on check tables or on other fixed information
Modification group 4: is not used
The FORM routine is called up for every field of a screen. If you require changes to be made, you must make them in this user exit. This FORM routine is called up by the module FELDAUSWAHL.

Add instance on Read only field issue

I have a subform with two fields , one a date field to capture current system date and time and another is a Text field for some comments.
Then there are two buttons ,one for Adding the instance for these two fields and another is a Save button which makes these two fields
The requirement is that once both the fields are filled with data and i click on save button, the fields should become read only ,however when i click on the add instance button the instance is added successfully but the save button click is not making the new instance read only.
The Code for Add Instance Button is :
"New1.FileNote.instanceManager.addInstance(true);
xfa.form.recalculate(true);"
The code for Save button to make the fields read only is :
New1.FileNote.DateTimeField101.access = "readOnly";
New1.FileNote.TextField37.access = "readOnly";
Please guide me as I am totally blank on how to code the same..Have a rough logic of using a for loop with index of the Add Instance but not getting the way out for the code.
Thanks a lot for any help and guidance.

Hi Steve,
Thanks for your reply..I made it happen using the for loop with Index and resolve node. However there is another issue which occured after that..I have a date/time field in that repeating subform instance.
The run time property is set to Current Date/Time. Now the issue is whenever i click on save, form.recalculate instance changes the existing time value in the previous subbform instance as well
Is there a way to retain the existing value in the field of the previous instance ??

May be the below code may help.. It loops thru all the pages in the PDF form and make them protected. So the user can not change any value in the form.
for (var i = 0; i < xfa.host.numPages; i++)
var oFields = xfa.layout.pageContent(i, "field");
var nodesLength = oFields.length;
//set the access type to be protected for all fields
for (var j = 0; j < nodesLength; j++)
var oItem = oFields.item(j);
oItem.access = "protected";
Thanks

Session state protection and read-only items

I have a requirement to create a report + form for a database table. In the form, there is mandatory database column that needs to be displayed but it should be read-only and its value derived using values entered elsewhere on the screen.
It tried Display Only, Read Only and Disabled but they either fall foul of session state protection violation or ORA-01400: cannot insert NULL. The best method that I've found was to add readonly="readonly" the item element, but this causes the input item to lose its APEX classes and I'd prefer a declarative solution anyway.
Anyone know the best approach?
I've created a DEMO - http://apex.oracle.com/pls/apex/f?p=READONLY - which demonstrates the 4 methods.

However a possible explanation/justification for this behaviour is that the HTML Form Element Attributes are often used to specify a custom class for the item, so the default class is removed to prevent any conflicts. IMO APEX needs to provide declarative support for the use of multiple, space-separated class values in page, region, item etc attributes.
As a workaround in this case, just include the class in the HTML Form Element Attributes:
class="number_field" readonly="readonly"

Thanks for making the effort.
