AdvTable-MultiSelect-Grey rows on which operation has been performed.

Question

I have advanced table, with multi select rows checkbox.
I need all the values of col1 of selected rows in advTableVo and insert it in a custom table attached with TestVO
once values of those rows are inserted in TestVO, select checkbox should grey out for those specific rows in advanced table.
This is what I did.
In advTableVO for adv table I added a transient String Attribute "SelectMultiRow".
Created multiSelections for my adv table.
Associated "SelectMultiRow" VO attribute, with multipleSelection1.
Under multipleSelection1, added a flowLayout, under it a submit button saying 'InsertSelectedRows'
Caught the action in PFR :
   if( pageContext.getParameter("InsertSelectedRows") != null);
      am.invokeMethod("InsertSelectedRowsInQuestion");
In AM :
//added col1 values of all selected rows to ArrayList
      listOfQuestionsToBeInserted.add(poRow.getAttribute("Question"));
for (int j=0; j<listOfQuestionsToBeInserted.size(); j++)
System.out.println(" looking inside ArrayList " + listOfQuestionsToBeInserted.get(j)); ///this prints fine.
// Check If the value already exists in Question column in customdb (TestVO)
// insert only unique values in TestVO
// once committed, How to grey out select checkbox for rows in advtableVO, which have been inserted?

Worked on your suggestion. I did get some of it working.
Im facing one thing, but it could be may not be an issue, please suggest .
There are 2 tables , table1, mastertable,
If value col1.mastertable exists in col1.table1 then disable checkbox -I did that based on your suggestion of spel.
now user selects few rows, and clicks insert button....
here in AM, I have this line of code :
if( (poRow.getAttribute("SelectMultiRow")).equals("Y") )
This throws NPE for rows which were already disabled at the time of rendering the page.
Is it ok to put it in try-catch block and just work with the values that display selected (Y ) ??
thanks
