Page change the current row when concurrent users press save in the same ti

I have a problem that appear only when a lot of users are running at the same time
that I have an editable form that have save button some times when I press save the current row that I edit is changed or return null row.
for example imagine that I edit employee that has Id = 50 when a lot of users running on the application at the same time when I press save the record changed to another employee that has id = 49 or returns empty form
in my code for save I call application module method that have code similar to this
        myViewRowImpl viewimpl =
            (myViewRowImpl )getMyView().getCurrentRow();
        getDBTransaction().commit();I build my ADF fusion web application using ver 11.1.1.3

Hi,
sounds like a passivation problem.You can also try and change the AM pool size.

How to Select the Current Row When Using af:iterator?

Hello all,
I encounter the following problem when using af:iterator to display data from
a View Object:
When trying to display the content of a row via a popup, only the first row is
returned no matter which row is selected. So a selection of the current row
should exist or some other method which should allow the access to the
current row.
The af:table has a selectionListener attribute which permit to achieve this.
Does anyone know about some similar attribute or some method for
selecting the current row when the af:iterator is used?
Thank you,
Mirela

I would be interested in the answer to this basic question as well. I cannot get the selected row value of an attribute in an iterator for a view if I simply set-up a attribute binding to the iterator. It seems that this should be possible. I've had no other option but to obtain the current row and the related attributes programmatically. This works fine, but if there is a more elegant option, then I'd certainly like to use it.
          <af:table value="#{bindings.CompaniesView1.collectionModel}"
                        var="row"
                        rows="#{bindings.CompaniesView1.rangeSize}"
                        emptyText="#{bindings.CompaniesView1.viewable ? 'No data to display.' : 'Access Denied.'}"
                        fetchSize="#{bindings.CompaniesView1.rangeSize}"
                        selectedRowKeys="#{bindings.CompaniesView1.collectionModel.selectedRow}"
                        rowBandingInterval="0" id="tCompanies"
                        summary="Companies"
                        width="100%"
                        rowSelection="single"
                        binding="#{CompanyBackingBean.companiesTable}">Page Def:
    <attributeValues IterBinding="CompaniesView1Iterator" id="Id">
      <AttrNames>
        <Item Value="Id"/>
      </AttrNames>
    </attributeValues>I should be able to get the Id attribute value of the current selected row using "#{bindings.Id}", right? Well, it doesn't work for me. Any ideas?
Thanks

Hi experts it is urgent, how to read current row when f4 is pressed

hi all
i have a field xyz which is input/output enabled. this field is attached with f4 help.
my requirement is to get or read the row when user press f4 on that field so that restrict value should come in f4 help.
right now f4 is showing all data, but i want data with respect to the row.
so how to get or read the row when user press f4 i.e user will choose any row and this out is on alv grid and there are multiple records.
i hope u understood the query.
thanx
rocky

Hi,
Use function module DYNP_VALUES_READ and then read the Tables parameter of this function module to get the value of the field. for demo program see this report 'DEMO_DYNPRO_F4_HELP_MODULE'.

How do i save a .m4v file to the movie folder when it will only save to the music folder?

I have a movie file in my ITunes music folder that i want to mover to the movie folder because it is a movie. The file type is a .m4v. When i click and drag it itunes wont let me drop it in movies.
What do i do??

You drag it using Windows Explorer and not in iTunes. Itunes library merely link the movie in iTunes library to your file location.
After you have dragged the file to another location, remember to link your original movie in itunes library to the new location. Right mouse click the movie, GET INFO, click LOCATE and direct to the new location (otherwise, your movie will not play)

Need to Set Current Row when Using Built-in Data Control Delete Operation?

I have an af:table bound to a ViewObject (VO) collection (no Entity Object) - within each row, I include a column that contains a 'Remove' command button so the user can remove the row. I add the command button by dragging/dropping the built-in delete operation from the VO on the Data Control Palette. When I use this as is (no changes), the Remove button always deletes the first row in the collection, not the selected row. Do I need to add code to set the current row, and if so can someone please provide an example and specify where I need to add? thanks.
------ .jspx af:table with command button to remove each row ------
<af:table value="#{bindings.ListView1.collectionModel}" var="row"
rows="#{bindings.ListView1.rangeSize}"
first="#{bindings.ListView1.rangeStart}"
// note: I don't have any code added for selectedRow or makeCurrent - assuming this is built-in?
selectionState="#{bindings.ListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.ListView1.collectionModel.makeCurrent}">
<af:column>
<af:commandButton actionListener="#{bindings.Delete.execute}"
text="Remove"
disabled="#{!bindings.Delete.enabled}"/>
</af:column>
---------- corresponding pagedef file ------------
<bindings>.....
<action id="Delete" IterBinding="ListView1Iterator"
InstanceName="SrchDataControl.ListView1"
DataControl="SrchDataControl" RequiresUpdateModel="false"
Action="30"/>
</bindings>
Note: I also tried solution posted on following thread, but again, only first row is deleted, not the selected row?: Delete and Commit

I just want to delete (or remove) it from the VO. Data for this VO is not on the database.
The function is doing what I want it to do (delete from the VO), its just always deleting the first row, versus the selected row. I select the command button next on a column next to an item further down in the list and it deletes the first row. The problem is setting the selected row to be removed - I thought setting the current row would be taken care of by the SelectListener?
selectionState="#{bindings.MyIspListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.MyIspListView1.collectionModel.makeCurrent}"

Maintain the current row position of a table after refresh.

Hi,
I use a poll to refresh tables continuously. when a table is refreshed, the current referring row is reset.
To maintain the current row position after a refresh I use the following poll method.
public void refreshTableT1(PollEvent pollEvent) {
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding dcb = fctx.getApplication().createValueBinding("#{bindings}");
DCBindingContainer bindings1 = (DCBindingContainer) dcb.getValue(fctx);
DCIteratorBinding dciter = bindings1.findIteratorBinding("<VOIterator>");
if(dciter!=null){
if(dciter.getCurrentRow()!=null){
Key current_row_key = dciter.getCurrentRow().getKey();
dciter.executeQuery();
if(current_row_key!=null){
try{
dciter.setCurrentRowWithKey(current_row_key.toStringFormat(true));
}catch(Exception ex) {
System.out.println("Exception in current_row_key");
}This works for normal tables well. But when I use it to master-detail tables (pair of tables) it does not.
At the master-detail tables, before the first data fetch, it works well. if we go below the first data fetch, it sets the current row into another position.
how can I overcome this...??
Thanks,
Dinuka.

Hi Mr.Frank,
I have an association in two VOs.
for example: There are 2 tables called Emp and Dept. Every Department has Employees. so there is an association (both tables have a common column). Master table is the Dept table. when you click on one record of the Dept table Detail table will show the details of the employees belongs to that selected department. That's what I referred as master-detail tables. first one is master table; second one is detail table.
When the web page loads all the table data is not fetched from the db (it will depend on the fetch size). when we scroll down the table data fetch happens again and again.
think my data fetch size is 25 rows per time.
Suppose we use mine poll method and think I have clicked on the 20 ^th^ row of table1(master table). then the table2 will display details belongs to selected department. that is OK even after refresh. that works well.
when I go to 30 ^th^ row data fetch will happen (my fetch size = 25)
when I click on the 30 ^th^ row of the table1(master table), table2 will display details belongs to selected department. but after the poll method is called the selected row at the table1 disappears and is set to another position. now the 30 ^th^ row is not in the 30 ^th^ position. but it is the selected row and table2 displays correct details.
I think you have got the problem now. :D
Thanks a lot.
Dinuka.

Change the current row in an iterator and reflect the change on page

Hi there,
I have a jspx with a creation form created as usual draging and droping the data control. In same page, I inserted a commandButton which ActionListener executes a method in a managed bean called validate(). Through such a method what Im trying to do is to fill the form with data from specified entry of the database if certain condition is true. I know it is kinda twisted but unfortunately is the requirement for the page.
So basically in "validate" method, if the condition I mentioned is reached, I do the following:
// execute a Rollback (included in Page Definition) in order to cancel the previous auto-invoked "Create".
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
BindingContainer bindings =(BindingContainer)app.getVariableResolver().resolveVariable(context,"bindings");
OperationBinding opBinding = bindings.getOperationBinding("Rollback");
opBinding .execute();
//get the iterator and asociated VO from the binding container
ValueBinding vb = app.createValueBinding("#{bindings.AccountsVOIterator}");
DCIteratorBinding dciter = (DCIteratorBinding) vb.getValue(FacesContext.getCurrentInstance());
ViewObject view = dciter.getViewObject();
//and set the current row with the specified entry I have mentioned above.
Object keyValues[] = new Object[2];
keyValues[0] = "1"; keyValues[1] = "98543";
Row[] row = view.findByKey(new Key(keyValues),1);
AccountsVpnVORowImpl client = (AccountsVpnVORowImpl)row[0];
view.setCurrentRow(client);
view.executeQuery();
dciter.setCurrentRowWithKey(client.getKey().toStringFormat(true));
dciter.executeQuery();
opBinding = bindings.getOperationBinding("Execute");
opBinding.execute();
All this works perfectly when I debbug it but I cannot see the changes in the page(even refreshing browser). I need that when such a condition is met, the creation form turns into a modify-specific entry form, filling all fields with the specific data in order user can modify it, and all in the same page.
Any clue?
Thanks so much in advance for your time.

Hi,
I could see the problem with call to executeQuery and execute methods at the end of your method which re-sets the current row.
Once you set the current row you should not call execute or executequery methods. Try removing those calls and also make sure that you have added partialTriggers property on the table is set to commandbutton id and partialSubmit property is set to true on commandButton to refresh the table partially on click of a button

Can any one tell me how to change the current row header in FB1LN tcode

Hi,
can any one tell me how to change the current row header in FB1LN tcode.

Hi
I know two ways:
- transaction obvu: here you can insert new fields, but only if these fields are included in certain table (like BKPF, BSEG, BSIS.....
- if your field isn't included in those table, you have to modify the structure RFPOS and manage it in the BTE 1650. After updating RFPOS you have to run the program RFPOSXEXTEND to update the structure RFPOSXEXT.

How to handle the current row with radio button selection???

Hi Everyone,
I have one ADF page with one table and one "Find" button.
I have created one new attribute with VARCHAR2(1) in the VO and dragged that attribute as first column in the table. And changed that first column to Radio Button to select only one row at a time.
Upon clicking on the "Find" button i need to get the values of current selected row.
How can i get the values of selected row?
What code should i write to get the values of selected row in Method Binding of "Find" button?
Any suggestions will be really useful.
Thanks.

Hello Kumar,
I have some comments on your case.
>
I have created one new attribute with VARCHAR2(1) in the VO
>
1- You should create this attribute in the Entity object and then add it to the view object.
2- Do you need that only one radio button is set at a time for all rows ? If yes then you need to handle the case when the user set more than one row and clear the value of the attribute for all other rows.
>
How can i get all the values of current row in backing bean method(method binding of Find method)?
can u plz provide me the code for that?
>
If you mean by the current row is that the row with its value of the selected attribute is set (the radio button is set for that row), then you can write a method in the viewObjectImpl class and expose it to client interface and call it from your bean.
here is an example based in Department table in HR schema.
//This method is written in DepartmentsViewImpl
public Row getSelectedRadioRow(){
            //create a second row set to not impact the row set used in ADF
            RowSet duplicateRowSet = this.createRowSet("duplicateRowSet");
            //get the current row of the table to set it back after re-executing the VO
            DepartmentsViewRowImpl currentRow = (DepartmentsViewRowImpl)this.getCurrentRow();
            Row[] filteredRows = duplicateRowSet.getFilteredRows("IsSelected", "1");
            DepartmentsViewRowImpl row=null;
            if(filteredRows.length>0){
                row = (DepartmentsViewRowImpl)filteredRows[0];
                System.out.println("Department Name " + row.getDepartmentName());
            this.setCurrentRow(currentRow);
            duplicateRowSet.closeRowSet();
            return row;
        }

Updating the current row in vo which is bind to af:table.

Dear all.
I have created af table by dragging datacontrol on page.. i also have a form and onclick of button i want to update the current selected row in table..
I am getting the current row properly but when i am trying to update the row.. it gives me following exception.
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Failed to lock the record, another user holds the lock.
oracle.jbo.AlreadyLockedException: JBO-26030: Failed to lock the record, another user holds the lock.
Following is my update code.
public void update(){
//BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Create").execute();
BindingContext bc = BindingContext.getCurrent();
JUApplication japp =
(JUApplication)bc.getCurrentBindingsEntry().get("Entries_AMDataControl");
Entries_AMImpl ampl = (Entries_AMImpl)japp.getApplicationModule();
ViewObjectImpl vo=ampl.getEntries_VO1();
Entries_VORowImpl row=(Entries_VORowImpl)vo.getCurrentRow();
row.setSubject(subject);
ClobDomain c=new ClobDomain(toXML().toString());
row.setXmlcontent(c);
row.setDescription("");
//vo.setCurrentRow(row);
//vo.executeQuery();
//BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Execute").execute();
BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Commit").execute();
So please can anyone there tell me how can solve this problem.
Thanks,

jdev version 11.1.1.4.0

Hi Frank
in your AM configuration, set the locking behavior to optimisticIts already optimistic.
is bad coding practice. You should perform updates through teh ADF binding layer and not directlxy against the Application Module Impl class. You can get the >current row from the iterator the table is bound to and set the attributes on itI changed my code to following
RowKeySet rs = getCalcTable().getSelectedRowKeys();
Iterator it = rs.iterator();
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding empIter =
bindings.findIteratorBinding("Entries_VO1Iterator");
StringBuilder sb = new StringBuilder();
RowSetIterator empRSIter = empIter.getRowSetIterator();
Row currentRow = null;
while (it.hasNext()) {
Key key = (Key)((List)it.next()).get(0);
currentRow = empRSIter.getRow(key);
break;
Entries_VORowImpl row=(Entries_VORowImpl)currentRow;
row.setSubject(subject);
ClobDomain c=new ClobDomain(toXML().toString());
row.setXmlcontent(c);
row.setDescription("");
BindingContext.getCurrent().getCurrentBindingsEntry().getOperationBinding("Commit").execute();
But it still gives me same error.
<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Failed to lock the record, another user holds the lock.
oracle.jbo.AlreadyLockedException: JBO-26030: Failed to lock the record, another user holds the lock.
Any suggestion appreciated..
Thanks

Is there a way to make the current row not editable

Hi, I'm using JDev 11.1.1.2
In my usecase I have a Form , navigateable with next/previous , and for every row a I have a calculation which makes the row editable or not.
For now I made it with disabled property on every input component set to some bean property which is calculated every time.
My question is if there is some general way to make an Entity not updateable ?
I tried with doDML() ... but the problem there is that this method is not called when switching the current row but rather when commiting. So the user can modified several rows and when pressing commit it will prevent some of the to be committed which would be confusing.
Is there a method in the ViewObject that i can overwrite which is called every time the current row is changed? So I can see if the row was modified or not.
Thanks, agruev

Yes, there is always isAttributeUpdateable() in the ViewRowImpl, which you can override and enable/disable your attributes based on an enabling/disabling condition.
Here is an example:
public boolean isAttributeUpdateable(int i) {
boolean updateable = false; /disable by default all arguments
// enable, if your condition is met
if ( meets_your_condition )
updateable = super.isAttributeUpdateable(i); // let the framework decide based on your declarative settings
return updateable; // return true/false indicator

Losing the current row without doing anything

I using 10g and my page have a VOR (viewobject readonly) to control form data but...
I'm losing several times the current row ... for example I put this code in a button:
public String clickAction() {
AdminUCAtoCartorarioAMImpl am = null;
try {
am = ( AdminUCAtoCartorarioAMImpl )super.getApplicationModule( "AdminUCAtoCartorarioAMDataControl" );
am.getAmbienteEscaninhoVOR().getCurrentRow(); //Here, sometimes brings me null.
} catch (Exception e) {
e.printStackTrace();
return null;
}

User,
You give us the symptom of the problem, but
I'm losing several times the current rowdoesn't help anyone to help you pinpoint what might be the cause. Under what circumstances does the current row come across as null? Are you manually iterating through the VO's row set somewhere? What happens before the current row is "lost?" What specific version (your tag indicates 10g, but specifically which version) of JDeveloper/ADF are you using? Does this occur only when deployed, or does it occur when running in the embedded OC4J.
One thing for you to try... if it occurs "sometimes," seemingly randomly under load, try turning off Application Module Pooling and re-test. If it occurs every time with pooling turned off, you are likely seeing some issue related to passivation/activation - which is why it would be critical to mention the exact version; there are known issues with specific versions, and there are patches available.

Select the current row in read only querry VO

Hi.,
I am using jdev 11.1.1.5
I had created a Finyear EO with corresponding VO
I had also created a read only querry VO [PostdGLhdlnVO]
I had created a viewlink between FinyearVO and PostdGlhdlnVO with following conditions
FinyearVO.bu = PostdGLhdlnVO.bu
FinyearVO.year = PostdGLhdlnVO.year
I need to select the current row and print that row using println statement. as i am using readonly querry while i drag and drop the PostdGLhdlnVO i cant able to select the current line (i.e., when user clicks the current row)
My scenario:
I need to create a non database checkbox for every row in that table [PostdGLhdlnVO] which will get the current row
can anyone help me to create a nondatabase checkbox for that table

Try,

Getting the current row in a datatable

Hi,
I am using datatable. How do I get the current row in the datatable
and use it for my processing in the JSP page
or I want to just output that value with out using any jsf tags.
Examples
<h:dataTable styleClass="dataTable" id="table1" border="0" value="#{myTrainingHandler.myMediaTraining}" var="dataIt">
<h:column id="column1">
<f:facet name="header">
<h:outputText styleClass="outputText" value="Course Name"id="text1"></h:outputText>
</f:facet>
<!---------------------------------------------- how do I get the value of #{dataIt.name} and use it in the JSP way
Reason: I just want to output the value. If I am using h:outputText then it inserts <span>... </span>
or, I want to transfer that value to another another attribute in the session or something like that.
---------------------!>
<h:outputText styleClass="outputText" id="text2" value="#{dataIt.name}"></h:outputText>
</h:column>
</h:dataTable>
-Aswath

It looks like good idea!Unfortunately this is just workaround. Indeed your
suggestion is real JSF-feeling solution but due to the
bug (or rather pure design of RI implementation???) it
is dangerous.
I had some doubt about is it bug or my incompetence.
Unfortunately this seems is really bug.
Hope this problem will be solved in the next releases.from blueprints catalog:
Component bindings (e.g. <h:inputText binding="#{MyBean.lastNameComponent}" />) should always be stored in request scope since their value is no longer valid after a request has been processed anyway. The component tree is reconstituted during each incoming request, changing the physical instances these component bindings will point to.
as you see there is really problem in using session backing bean with component binding
so that means idea with parameter looks better now because we don't need to use table binding.
Or probably we can define some kind of pattern like couple of beans with request scope and session scope.
for example:
Catalog - session scope
CatalogView - request scope
Catalog will keep session data and CatalogView will provide some presentation logic (including some stricly visual oriented data) and access to business methods of Catalog class.
I will send you example by e-mail (on friday) if you not mind.

Thank you for your suggestion!
Probably I will use your idea in my application.
By the way I'm from Kiev also.Hello from Kiev :-)
I have one suggestion.
I'm working on JSF form that suppose to add, editand
delete records from table.
Also I wanna to use scrolling by page and sorting.
I'm trying to make this form somehow clean and
universal as much as possible.Seems I have same tasks for now.Great! I will send some code soon.
And maybe we can discuss every aspect how to do good JSF based application including config oriented information and utilities classes.
-how do you work with tables without primary keyI dont' have tables without primary key :)
-how do you make pagination by universal wayWe need just make good component for that.
We already started in this direction.

Get the icon for the current row selected

Hi !!
I am using jdeveloper 11.1.1.5
I had dragged and dropped my ApplBusFunVO as a af:tree
My Output will look like this
Supplier Balance
Supplier Document Details
Purchase order
Purchase ReceiptsMy af:tree doesnt contains the Parent
My Scenario:
When my user clicks the current node of the tree!! an icon should appear before the current node is selected
For Eg: If my user clicks the Purchase Order then my output should like this
Supplier Balance
Supplier Document Details
==>Purchase order
Purchase ReceiptsThe Symbol ==> Represent the icon! that appears before the purchase order!!

Hi
<af:tree value="#{bindings.SalesPeople.treeModel}" var="node"
          selectionListener="#{bindings.SalesPeople.treeModel.makeCurrent}"
          rowSelection="single" id="t4" fetchSize="35">
          <f:facet name="nodeStamp">
             <af:group>
                  <af:image id="cl3" source="#{reference_to_image_url}"
                  rendered="#{check_if_current_row}"/>
                  <af:outputText id="ot2" value="#{node}"/>
             </af:group>
   </f:facet>http://docs.oracle.com/cd/E23943_01/apirefs.1111/e12419/tagdoc/af_image.html
As mentioned in a previous answer to this very same question, the tree is a stamped component which means that you need to partially refresh the tree component to show the icon. You can us the selectionListener (override the current setting to use a managed bean setting the current row - calling the same EL) to determine the new selected row key and then use the rendered option to determine (using a managed bean reference) if the current rendered node (#{node} is accessible from a managed bean at render time) is the selected node.
The side effect is that upon tree node selection the tree will "flicker"
