Answer 1

balu i have tried by seeing u r blog.
this is my structure of tables
plexes (if i iterate plexes table gives plex object)
|
------ plex (plex table gives transaction object)
|
------transactions(transactions table gives transaction table)
|
here i will have a command link to this link i have to pass the plex name which
will come from
i tried in this command action with HTMLDataTable getRowData()
i am not getting the selected row data .i am downcasting this getRowData() to plex.
