Make lov required programmatically

Question

I have a table :
select  col1   col2-lov
o            1      lov1     
o            2      lov2     
o            3      lov3     
o            4      lov4 If any row is selected , then corresponding col2lov should become required to be picked before user can do anything else.
How can I do it ?
I tried setting the required attribute based on vo's boolean attribute , and setting it to true when the row is selected , but this logic doesnt seem to work.
any pointers ?

I think your requirement is:
User will select particular row in say advanced tableusing select checkbox. In this case you want to make col2LOV mandatory.
Do following:
1) set required property of item to like this: ${oa.*current*.transfielddisable}
2) getfirstfilteredrow'Y' for your select checkbox or radio button, to check which checkbox user has selected.
IF you need you can use : in CO call AM method using
String rowReference =
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] parameters = { rowReference };
Object lecolname = AM.getlegcolname(rowReference);
here row reference will give you current pointer to row..
I am sure, using above 2-3 concepts you should be able to solve the problem.
