Target Unreachable, identifier 'row' resolved to null
stammineOct 21 2009 — edited Oct 22 2009Hi,
I have created a ViewObject Query based.
I have set the Key attributes.
I have set the attribute properties to Updatable Always.
I have created a page with Updateable Table with the created view object.
I have set the Auto submit property to true for one of the column.
When I change the value in that column I get "Target Unreachable, identifier 'row' resolved to null" error.
I have got some insight why this may occur from the Jobinesh's blog.
http://jobinesh.blogspot.com/2009/06/target-unreachable-identifier-row.html
Not sure how to handle this.
Below is the stack trace from my diagnostics.
