Creating row in a recursive view having read-only attribute

Hi All,
I am using Oracle JDeveloper 11g Release 2.
I have a view AppMenusVO with the participation of following entities:
1. AppMenusEO *(Updateable)* with columns like MenuId, MenuName, MenuIcon, MenuParentId, MenuTaskflowId
2. AppTaskflowsEO *(Reference)* with columns as TaskflowId, TaskflowName, and TaskflowURL
3. AppMenusEO as ParentMenus *(Reference)* with columns as ParentMenuId, ParentMenuName
Next I created a One..Many view link where source and destination entity is the AppMenusVO based on relation (MenuId=MenuParentId). The name of the view accessor is MenuChildren.
This view is used to create af:treeTable component on the adf page. In order to create new row I am following the blog entry at http://jobinesh.blogspot.com/2010/05/crud-operations-on-tree-table.html.
I created a business method in the application module with the following specification:
    public void createMenuChildren(RowIterator ri, Key selectedNodeKey) {
        if (ri != null && selectedNodeKey != null) {
            Row[] found = ri.findByKey(selectedNodeKey, 1);
            if (found != null && found.length == 1) {
                System.out.println("Node found for : " + selectedNodeKey + " Parent Id : " +
                                   found[0].getAttribute("MenuParentId"));
                Row foundRow = found[0];
                RowSet childRows = (RowSet)foundRow.getAttribute("MenuChildren");
                while (childRows.hasNext()) {
                    Row r = childRows.next();
                    System.out.println(r.getAttribute("MenuName"));
                Row childrow = childRows.createRow();
                childrow.setAttribute("MenuParentId", foundRow.getAttribute("MenuParentId"));
                childRows.insertRow(childrow);
            } else {
                System.out.println("Node not Found for " + selectedNodeKey);
    }When I invoke this method from the adf page it is giving the exception An attemp is made to validate an already invalid region site.
The Jdeveloper console is also throwing the exception oracle.jbo.ReadOnlyAttrException: JBO-27008: Attribute ParentMenuName in view object AppMenusVO_MenuChildren_ParentMenusVL_AppMenusVO cannot be set.
I searched Google and OTN but unable to resolve the error.
The solution I have tried are:
The default activity on the BTF is marked and is pointing to a valid view.
Set the activation property of region to immediate ... etc.
BUT the issue persists.
Any help to create row programmatically in recursive view where some of the attributes are read-only?
Thanks in advance
Best Regards
Bilal

Hi Frank,
Thanks for the response.
The updateable property of ParentMenuName attribute is Never and is being disabled so I am unable to change its value. Moreover, never in my code I am changing value of this field. What I am doing is trying to create a new row and then insert it into rowset. I don't know how to proceed further.
One more thing is that I have an LOV on another column MenuParentId which returns value in this field as well. It might be the reason? ...
Any help will be highly appreciated.
Thanks

Sharing a view in read only mode

Hi,
I am new in this domain. I have made an application in which I made two local development projects. Through that I am using views of one into another with the help of "Used WebDynpro Components" concept. After deploying, I have got these two views.
But the problem is that I want that view in read only mode which I have taken from other local development project and this view was not in read only mode in its local development projects.
Please provide me the solution in detail so that I can understand easily.

Hi Manish,
Say View1 is the view in main Component,View2 is the view in used Component. Exactly follow these steps.
Create a context attribute enable of type String in used Component's controller,used Component's Interface controller, View1 and View2.
Using context mapping map these attributes View2 -> used Component's controller-> used Component's Interface controller -> View1 ( if you don't know how to map double click the the Main component: Data navigation modeler is opened; In the diagram, right side select small arrow first select View1 drag to used Component's Interface controller,in the wizard select right hand side enable attribute drag to left side)
you can map similarly View2 -> used Component's controller-> used Component's Interface controller.
In View2 create another variable edit of boolean type.
Open Layout tab of View2, bind this attribute to enable property of all the UI elements which you want to disable.
In implementation tab of View1 in method wdDoInit() write this code
wdContext.currentContextElement.setEnable("display");
In implementation tab of View2 in method wdDoInit() write this code
if(wdContext.currentContextElement.getEnable().equalIgnoreCase("display"))
wdContext.currentContextElement.setEdit(false);
else
wdContext.currentContextElement.setEdit(true);
Hope this helps for you.
Best regards,
Siva

"Edit Locally" for Repository having "Read only" rights

hi,
    I am on EP6.0 SP9.
When I go to
     Content Administrator --> KM Content --> Repository(having "Read Only" rights), and click on "Context Menu" an option "Edit Locally" come there. But as the repository has "Read only" rights, I need to disable that option.
Is there any way to do that?

Hi Patricio,
            Perhapps that link is not woking fine, so i have pasted that code here, so please have a look at the code here,
public void received(IEvent event) {     IRecipient recipient = null;
     IResourceEvent myEvent = (IResourceEvent) event;
     IResource res = (IResource)event.getParameter();
     System.out.println("Event");
     String resname = res.getDisplayName();
     try{
     ISubscriptionManager subscriptionManager =
com.sapportals.wcm.repository.service.subscription.SubscriptionUtils.getSubscriptionManager(res);
     ISubscriptionCondition mycondition =
subscriptionManager.createSubscriptionCondition();
     mycondition.setInterval("ALWAYS");
     mycondition.setRecursionLevel("999");
     mycondition.setRidTracking
(subscriptionManager.getDefaultConditionRidTracking(res));

Lifecycle issue with table binding + read-only attributes: ADF BUG

Hello all,
I have found what I believe to be an easily reproducible bug in ADF that reproduces in 10.1.3.x, but not in 11g (at least not in drop 6). The best way to describe the bug would be to walk through a simple set of steps to reproduce the bug:
1). Create a new application (ADF BC + ADF Faces).
2). In the model project, create a new Entity Object from the Employee table in the default HR schema. Allow JDev to create an updatable view object and an AM as well.
3). Put a validation rule on the first name attribute of the EO (can be anything, really - I made mine so that the first name cannot be "foo").
4). Test everything using the BC tester if you like.
5). In the UI project, create a new JSPX page.
6). Drag the updatable VO on to your page as an updatable af:table.
7). Put an af:commandButton on the page. Bind its Action or ActionListener to a method in a new backing bean. Put some simple code (I used System.out.println) in the backing bean method.
8). Run the jspx page.
9). Put some invalid data in (e.g. "foo" in the first name field) and click the af:commandButton. Verify that you get an error message and that the Action/ActionListener method DOES NOT fire. So far, so good.
10). Now, to demonstrate the problem. First, look at the page definition for the jspx file. Identify the first attribute that is mentioned (in my case, it was the employee id).
11). Go to the updatable view object and make the attribute from #10 read-only or updatable when new only.
12. Now, repeat step 9 - you should see the error message AND also see that the Action/ActionListener method was executed. You will also see in the messages window that ADF attempted to set the value of the read-only attribute, and thus got a ReadOnlyAttrException.
This issue only happens if the first attribute mentioned in the table binding is read-only. A workaround would simply be to re-order the attributes in the table binding of the pagedef so that the first attribute isn't read-only.
Don't ask how I figured this out ;)
Best,
John

Hi Frank,
Yes, I simply scripted it out this way to contrast the behaviour if the first attribute was read-only vs not read-only. I found the issue on a page in our app that was simply drag-and-drop the VO from the data control on the page.
It's quite annoying, because our particular use case that hit this error is a "save" button on the page. If the commit operation doesn't return any errors (and it doesn't in this use case!), we add a JSF message saying "save successful" - then the attribute errors are further added later in the page lifecycle, so we get 3 messages: "Save successful" and "Fix this error" and "Tried to set read-only attribute" - quite confusing to the end-user when the only message they should see is "fix this error."
At any rate, the fix is to simply re-order the attributes in the page definition - that doesn't affect the UI at all, other than to fix this issue.

Updating read only attributes of class/method

Hi,
I have this standard class CL_QNAO_OBJECT, with MS_DATA as read only attribute.I have written my own class in an enhancement within this class and now trying to edit this MS_DATA within my own class. but I get an error sayng "write access to the READ only attribute is not allowed", is there any way I can change it?
The attribute MT_STACK is changing attribute/parameter to my class, which in turn has this ms_data structure.
Note - I did search sdn before I put it here, I got couple of threads which I dont find suitable for me.
Thanks in advance,

Since MT_STACK is also type ref to CL_QNAO_OBJECT, my earlier guidance still hold true.
Step 1 - When you enhance the class, you would see empty table lines in the class editor. Create a new method in that.
Public Instance Method name Z_SET_MS_DATA
Importing parameter IS_DATA TYPE QNAOD_AOBJECT
Method implementation:
ME->MS_DATA = IS_DATA
Step 2 - In you enhancement in the class, call the method to set the data
Data: ls_Data type QNAOD_AOBJECT
Ls_data-field1 = ‘xyz’.
core_object->mt_stack->z_set_ms_data( ls_Data ).

Updating Media Content - stuck at Reset Read Only Attributes.

I'm currently using - MDT 2010 on Windows 7 on a Virutal Machine. I deploy my images using a USB stick. (Advanced Configuration / Media). The process of creating a selection profile, Creating Media, and updating my media works perfectly.
I wanted to move to MDT 2012 SP1 on Server 2008 R2 platform. So I installed AIK, MDT 2012 SP1, etc on a Server 2008 R2 Virtual Machine. I setup the MDT same way as my current working model and it was looking good. Next I created my Selection Profile
and Media. Then when I ran "Update Media" it seems to work until it gets stuck at the last process "Reset Read Only Attributes"
Looking for any advice on why it might keep getting stuck here. The only way I can exit the process it to "Stop Execution"
Reminder - on my Win 7 / MDT 2010 box, it works fine and this process completes.
Thanks for any feedback.

What is happening here is that MDT Litetouch console is calling OSCDIMG.exe, and that program has stopped.
Sadly, MDT does not capture the OSCDIMG.exe output for analysis, so we are stuck here.
I have personally encountered problems with OSCDIMG.exe running on my Windows 8 box, where images created with source files from the C: pass, however when the source files are placed on a "Storage Spaces" volume, the program hangs. No response from MSFT.
If you need help diagnosing the problem, you can run OSCDIMG from a console window, just to see what the output is
OSCDIMG.exe -u2 -udfver102 -m -o -h -w4 "<MediaSrc>" %temp%\Dest.iso
Longer:
OSCDIMG.exe -u2 -udfver102 -m -o -h -w4 -yo"<Path_to_Bootorder.txt>" -bootdata:2#p0,e,b"<Path_TO_ETFSBoot.com>" #pEF,e,b"<Path_TO_EFIsys.bin>" "<MediaSrc>" %temp%\Dest.iso

How to remove "Read Only" attribute on folders

Hi
I am logged in with my User account which has full control over my folders.<o:p></o:p>
I have a folder that I tried to add modifications to, however i could not do so because the folder was classified as read only. I have full permissions to this folder. Previously the app that
uses this folder could write to it quite happily, but today it fails. <o:p></o:p>
The 'attributes' for the folder shows a solid square in the read-only box. If I 'un-box' the read-only and apply > ok, when I look at the attributes again the box is still checked.<o:p></o:p>
So my question is, if it's not (which it shouldn't be) some sort of protected Windows folder, and I have full permissions on the folder (supposedly), why does Windows not respect my wishes,
get out of the way, and let me set it to what I want it to be?<o:p></o:p>
I have tried the following methods to fix this issue, but none of them work:<o:p></o:p>
-Adjusting permissions and control, and changing security options<o:p></o:p>
-Using a third party application such as "clear read only" to remove the check on the box<o:p></o:p>
-Using the "attrib" function on the CMD prompt<o:p></o:p>
-Boot Scan for virus/malware that is affecting folder attributes<o:p></o:p>
-Running applications and CMD as administrator<o:p></o:p>
I have heard that if using a NTFS harddrive, then all folders will be automatically “Read Only” and that it is impossible to change that attribute. I find this hard to believe, as all folders
should have some way of being modified, regardless of what HDD I’m using. I obviously cannot change to FAT32, so how else can I get my folders to get rid of this ridiculous error!
<o:p>I have also noticed that this problem is very common amongst Windows users. If this problem has been around for a while, how is it possible that no solution has presented itself.
Regardless, we need a solution to it, because i can't do the things i need to while the Read Only attribute remains a constant on my folders. I thought it may be a virus, but my avast anti-virus did not pick up any infected areas when the scan was done. I
have searched the internet, and no "fix" has solved this issue. The only fix i have not found is a reg edit that could completely remove this read only attribute from all folders. Though i feel this is not neccesary, as i only need the attribute
to be removed from certain folders. Please kindly assist me with this issue, hopefully it will help many others too...</o:p>
Many thanks.

Have you taken ownership of the folder? Please first take ownership of the folder, then change the security options
Take Ownership of a File or Folder
http://technet.microsoft.com/en-us/library/cc753659.aspx
If you have already did this, then run a scan with this tool,

or copy this folder to another location, test again.

Public Read-Only Attributes

I'm trying to pick up ABAP on my own by reading through various resources I've collected and writing my own programs. Unfortunately I don't have an experienced ABAP guru to ask questions of. I'm hoping someone can help me with the following:
Based on my other programming experience I know that it is very common for object attributes to be defined as private and then accessor/mutator (getter/setter) methods to be defined to provide access to the attribute.
In my study I noted that ABAP allows attributes to be made public but declared to be read-only. This would seem to permit a structure where accessor/getter methods are not needed (the attribute can be read externally) and one would only have to define a mutator/setter method.
My question: what is typically done in 'real-world' programs? Is there any reason why using read-only would be more or less preferred?
Thanks for any help that can be provided.

Hello Tony
Below I have listed a few examples from standard ABAP classes. I cannot say whether you find more public read-only attributes than GETTER methods - you will find examples for both of them.
I could imagine that before it was possible to use the functional method call in ABAP that public read-only attributes were an alternative to the "verbose" method cal (see below)l.
" RE-FX: Contract
CL_RECN_CONTRACT-IF_RECN_CONTRACT~MS_DETAIL   " public read-only attribute
" MM: Material
CL_IBASE_R3_MATERIAL->GET_MARA " GETTER method
"FI/CO: Company Code
CL_REEXC_COMPANY_CODE=>GET_DETAIL " GETTER method
" HR: Employee
CL_PT_EMPLOYEE->IF_PT_EMPLOYEE~PERNR   " public read-only attribute
" Assumption: CL_IBASE_R3_MATERIAL would have
" a public read-only attribute MS_DETAIL (of TYPE mara)
" Normal method call (verbose):
CALL METHOD go_material->GET_MARA
RECEIVING
    R_MARA = ls_mara.
" Functional method call:
ls_mara = go_material->get_mara( ).
" Accessing public attribute
ls_mara = go_material->ms_detail.

Read only attributes turned on by Windows 10

Two days after installing Windows 10, all of my data files are suddenly read only. I cannot save any files. I went to setting, turned the read only attribute box off, and the system seemed to be turning them all of. At least it ran through the entire data directory file by file. When I went to open a file in my word processor, it came up as read only, and of course I could no longer save the file junder anyu name. A check of the attribute box in settings showed that read only had been turned on. This makes the entire system useless and puts me out of business. Fortunately I still have my old XP netbook so I can continue working, albeit at a much slower pace.

By default, OU1 is mapped to directory attribute "ou". It's not modifiable via calendar. You could use the other OUs attribute (OU2-OU4) for this purpose.

Updatable view and Read only view

Jdev version 11.1.1.6
1. Can we use an updatable view instead of readonly view for LOVs?
2. In my use case, I am having a panel-tabbed component. I create Region in the first tab & create Countries in the second tab. If I use a LOV for Regions based on the read-only view, then the data created & COMMITTED in the first tab is not getting reflected in the LOV in the second tab. But, if I use an updatable view for the Region field's LOV, then the LOV works fine. But, want to know if it is fine to use an updatable view for LOVs.

Quotation from the developer guide
>
Best Practice: When you need to create a read-only view object for
data lookup, you should use the entity-based view object and deselect
the Updatable option in the Entity Objects page of the view object
overview editor.
>
>
View objects can either be related to underlying entity objects or not. When a view
object is related to one or more underlying entity objects the default behavior supports
creating new rows and modifying or removing queried rows. However, the update
feature can be disabled by deselecting Updatable in the overview editor for the
entity-based view object

So the answer for your first question is Yes

Inserting a new row in a BC4J View Object with an attribute of type BFileDomain

Hi all,
I've to insert a row in a View Object with an attribute of type oracle.jbo.domain.BFileDomain.
I do this within an Application Module's method, which has an input parameter of type byte[]. This parameter will be the content of the BFILE.
What's the right way for doing that?
I've tried with the following code, but I've got an exception in committing the transaction:
public int serializeDocument(int codDomanda, int codSorgente, byte[] content, String est, int type, int cost, String title, String arg) throws JboException {
int code = 0;
//File f;
DocumentiTwoView = getDocumentiTwoView();
java.sql.Statement stmt = ((DBTransaction) getTransaction()).createStatement(1);
try {
Row docRow = DocumentiTwoView.createRow();
SequenceImpl seq = new SequenceImpl("documenti_seq", getDBTransaction());
Integer next = (Integer) seq.getData();
code = next.intValue();
docRow.setAttribute("Coddocumento", new Number(code));
docRow.setAttribute("Titolo", (String) title);
docRow.setAttribute("Argomento", (String) arg);
docRow.setAttribute("Costo", new Number(cost));
docRow.setAttribute("Tipo", new Number(type));
docRow.setAttribute("Coddomanda", new Number(codDomanda));
docRow.setAttribute("Codsorgente", new Number(codSorgente));
//f = new File("Doc" + code + "." + est)
BFILE src_lob = null;
ResultSet rset = null;
rset = stmt.executeQuery ("SELECT BFILENAME('DOC_DIR', 'Doc" + code + "." + est + "') FROM DUAL");
if (rset.next()) {
src_lob = ((OracleResultSet)rset).getBFILE(1);
BFileDomain bfd = new BFileDomain(src_lob);
bfd.setBytes(content);
bfd.saveToDatabase(getTransaction());
docRow.setAttribute("Contenuto", (BFileDomain) bfd);
catch (Exception ex) {
getTransaction().rollback();
throw new oracle.jbo.JboException("Impossibile creare il nuovo documento:\n" + ex.getMessage());
finally {
try {
stmt.close();
catch (Exception nex) {
try {
// Commit the whole transaction
getTransaction().commit();
catch (Exception e) {
e.printStackTrace();
getTransaction().rollback();
throw new JboException("Impossibile eseguire il commit della transazione:\n" + e.getMessage());
return code;
Thanks a lot in advance!

Odd, have you disabled caching and indirection? (NoIdentityMap, dontUseIndirection, or alwaysRefresh/disableCacheHits). If so, then this could be the issue.
Otherwise please include the sample code you use to perform this, and verify that you do not have any unusual code in your set/get methods or in descriptor events. Also turn TopLink logging on and include a sample. Also ensure that you do not modify your objects until after registering them in the unit of work, and only modify the unit of work clones.

Add Row on Tabular Form - column from read only to update/insert allowed

APEX 4.2.2
Newbie in the APEX forums, go easy please.
I'm building a rather simple tabular form based on a table with a primary key (emp_number). Sounds like an Oracle tutorial but trust me, it's a real table. This table has, for this example's sake the following attributes:
Table Name: EMP_EXCEPTIONS
EMP_NUMBER NUMBER (PK)
UPDATE_EXEMPT VARCHAR2(1)
I've used the Tabular Form wizard to create a nice looking tabular form page, all good and works as intended. Of course the primary key value is non update able by the wizard and that's by design - I've no need to update any primary keys. When I click the add rows button however, I'd like to be able to include the emp_number field as a input able field. At the moment, when I click the add rows button it inherits the property of the emp_number as read only. The user entering the new row would know the employee number and whether they were update_exempt or not. So rewinding my head in Oracle Forms, this would have been done by setting the row attribute as update allowed when the button is clicked. Is there such simple functionality in APEX and if so can you point me in the right direction?

It seems to be true:
- if there is ascending order on columns which fields are null in new line (have no default value), new row is visible in current "pagination" page
- but if there is DEScending order OR ANY sort order is set on columns which fields are NOT null in new line (have default value), new row is NOT visible in current "pagination" page
thank you!

HT1529 Excel spread sheets created on a PC show up as "read only" when opened in my iMac which has Excel. How do I correct this?

Excel spreadsheets created on PC shoe up as "read only" on my iMac 27 also in Excel. How do I correct?

Are you saying when you open the Info window on the file and try to change the permission it won;t let you? Do you get any messages? Is the account youare using an Admin account?
If you could post a screen shot of the Info window opend on the file in question it could help.

Unlock a FM file that does not have the Read-only attribute?

I have FrameMaker 8.0p277. I was trying to import formats from a file on my network. Everything froze. I had to reboot. When I reopened my FM book file and the individual chapter files, I got the lock message that prompted me to reset the lock and open each file. I did that--opened each file and reset the lock in each file. However, when I go to update my files, I get a message that one of my files is read-only. The attribute settings does not say this. I also can't even click in this file any more. I tried removing it from my book file and adding it back in. But that didn't change anything. Is there a way to get this file unlocked again?

This happened to us once.
Be sure you are pressing the keys sequentially, except for F, that is:
Esc
Shift+F
l
c
Except for Shift+F, do not press all the keys at the same time.

Permit user to administrate Model AND have read-only attributes

This issue concerns SQL Server Master Data Services 2012
I have a scenario where the same user is handling data and doing version management. Now I want to make one attribute in one specific entity read-only as I want to make sure the attribute is never changed.
The problem is, as soon as I set the read-only privilege on the attribute, the user
loses all administrative rights on the entire model. This, of course, includes version management.
I've tried working around the issue by making sure the user has explicit update permissions on both the model and the entity (and all attributes except the one I need read-only). But the result is the same.
Does anyone know a workaround?

Hi,
I think if you explicitly grant the update permissions, it should work. According to the MSDN doc. Could you please check if the user belongs to other hierarchy?
When a member belongs to multiple hierarchies
Two or more hierarchies can contain the same member.
•If one hierarchy node is assigned Update permission and another is assigned Read-only, then the members in the node are Read-only.
•If one hierarchy node is assigned Update or Read-only permission and another node is assigned Deny, then the members in the node are not displayed.
