object browser issue

We are using flex application .flexobject internal methods and properties are displayed and the user is able to set values using the listed methods avilable in object browser.
However after saving the data, when we tried to modify the data, the test failed.
When we checked the object browser for this object, object browser didnt display the object internal methods and properties for the data we added earlier, say it is in the first row.

However we manually added a row and test complete object browser display the internal method and properties for the new row.the problem is object browser doesnt display method And properties for the rows that are saved already.hence we cannot modify the data set inthe previous saved rows.
