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

Question

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
