i tried to implement a lov function in my uix application as it is described at http://www.oracle.com/technology/obe/obe_as_1012/j2ee/develop/client/uix_lov_obe/uix_lov_obe.htm
it works just fine as long as i only try to edit existing records.

after clicking on a button to create a new record and trying to use the lov function the text field doesn't get filled but i don't get any error message either
if i give it a second try it works again, same if i submit the form and then try to edit it again

i also have another lov field working even worse..
the only difference i can find between these two fields is that this attribute is only "updateable while new"
having a new entry it simply does nothing just as the other field, but giving it a second try doesn't help as i get a "Row currency has changed since the user interface was rendered. The expected row key was null" error.

anyone ideas?

Hi Didier,

thnx for ur quick reply, unfortunately it didn't solve my problem as my Create control action binding is already set to "CreateInsert" (I don't even have a single "Create" in that list)

thnx in advance for any other ideas

Hi Didier,

my application was using batch mode, but the errors still occur after switching to immediate.

The problem definitely is that the creation isn't complete yet after clicking the button. If I add a read-only table to the same page, the newly created row doesn't appear after creating the new record. It does appear after trying the lov for the first time.
Maybe there's some kind of workaround by adding some functionality to the create button by hand so the record is fully created?

I didn't solve my second problem concerning lov either. If the attribute I try to fill is a foreign key (same with primary keys) i get an "JBO-33035 Row currency has changed since the user interface was rendered. The expected row key was null" error. Any ideas for this one?

I'm very new to these technologies, so maybe it's a very simle thing I missed, but I really don't know what to try....

I do not have access to MetaLink.

best regards,

Hi Didier,

I am using Version 10.1.2.1.0 (Build 1913).

Entering the value manually works just fine. I have two Entity Objects in the View Object and I also had an attribute marked as "Key Attribute". Removing this setting solved the problem => thanx !

Concerning the Create problem, yes, I am absolutely sure that "CreateInsert" was already set (as I mentioned before I don't even have a "Create" Binding to choose). Nevertheless I now tried to set the Binding to some other value and reset to "CreateInsert" again. Now it worked !

Looking in the UIModel XML file I also got the reason for this.

In the beginning the "Action" value was set to 41 (seems to be "Create"). After I re-chose the CreateInsert binding it is now set to 40 (being the "real" CreateInsert).
Looks like a bug ?!

Well, now everything is working so far, so thanks a lot for your help and patience

best regards,

michi
