ADF Table dynamic rendering issue with Transient VO

Question

Hello All,

My page header and lines section. Header section is designed using af:panelFormLayout and lines section is constructed using af:table. Header and Lines regions are on two different Transient VOs which has no queries and updatable option in all the attributes set to always. As per the requirement after some condition, i will have to disable few column items in the lines table. For this, i have created new Transient attribute (SpecEditMode) of type Boolean in lines transient VO and i set this attribute value to Boolean.TRUE or Boolean.FALSE based on the condition. I set read only property to all af:inputText fields as #{bindings.SpecEditMode.inputValue}.
Here is the my lines table layout structure
af:panelBox
     -> af:panelCollection
     ->-> af:table.
I have one input text box to get number of rows to be added to line in the af:panelBox toolbar and a GO button to create the rows.     Here is the steps to get my issue
1. Create new rows in the Lines Transient VO based on the user input.
2. Perform business logic and lock the rows created above (set the read only propery to true using expression #{bindings.SpecEditMode.inputValue})
3. Rows created in step one gets locked when the layout gets refreshed.
4. Repeat the step 1 and now all the locked rows becomes unlocked.
To debug further on this, i drag and drop the SpecEditMode attribute as a column in the same table to verify the values during runtime. SpecEditMode attribute value for Rows created in step 1 are true which is supposed to lock the row.[But not locked the rows] and for all the newly created rows in step 4 are false.
Eventhough the SpecEditMode attribute values are correct, the fields are not locked after the first time.
Could you let me know if i am missing anything? Very much appreicate any pointers/inputs. Kindly suggest if there is any other better way to achieve the expected functionality.
Thanks

Answer 1

When i set the read only property to #{row.bindings.SpecEditMode.inputValue}, the dynamic behaviour is works just fine.
