Issue with ‘Set Source Order’ in VO wizard - ADF

Problem statement: 

I had VO with few Transient Attributes. These attribute values needs be populated based on calling DB package call. 

I already had Java wrapper class contains logic to call DB packages

So I  override my createInstanceFromResultSet method in VO Impl to populate transient attributes.

My page is search page, so created view criteria on VO to create standard query panel.

At later point, I wanted to re-order or shuffle attributes/fields in the standard query panel.

So I used ‘Set Source Order’ option to re-order the attributes.

Problem it created: attribute mis-match happened and one attribute showing another attribute value.

                                                                                       

Solution I did: Taken backup of VO impl custom method(other than setter and getter methods)and VO Row Impl and Client interface(VO-Java file),

          Go to VO wizard.

       From the Java section un- check for VO impl and VO Row Impl

      Select  ‘Query’  options from the left panel and click on ‘Update Mappings’ button

Once done, just restart the JDeveloper, and Generate VOImpl , VORow Impl  and Client interface java

Copy custom method you implemented in VOImpl from back up file and re-run. It works fine for me.

As per my observation, whenever you want to change VO query/ attribute order, it is better to do it in source mode instead of directly doing in wizard

Hope it helps!...
