Get Row Id From A Display Tag Table On A Jsp, Into A Struts 2 Action Class

I am using display tag to display data in a table on a JSP. Now I want to give two links for each row, one for editing & one for deleting the row. There are some posts on stack

Solution 1:

The current element of the list is available through the page context attribute "foobar" if the display:table tag has the attribute uid="foobar" (or id="foobar"). See http://www.displaytag.org/1.2/displaytag/tagreference.html

Solution 2:

Display Tag uses Implicit Objects to store the row number. Here is an example from the Display Tag documentation:

<displaytableid="row"name="mylist"><display:columntitle="row number" ><c:outvalue="${row_rowNum}"/></display:column><display:columntitle="name" ><c:outvalue="${row.first_name}"/><c:outvalue="${row.last_name}"/></display:column></display:table>

So you can use EL to access the row number which is stored as an automatically created object. Its name is defined by your id variable (in this case row) with appended _rowNum (in this case resulting in ${row_rowNum}).

Be aware that the numbering starts at 1, not at 0.
