Where is the link going? What url you see in browser when you click the link? – Huoh

What do you mean by doesn't go anywhere? What url you see in the browser? Also you can check the view source to see what url generated. – Huoh

Answer 1

It is done by the following code.

<display:column  title="Edit">
                    <s:url id="updateUrl" action="marketing/update.action">
                        <s:param name="id" value="#attr.countrylist.id" />
                    </s:url>
                    <s:a href="%{updateUrl}" theme="ajax"  targets="countrylist">Update</s:a>
                </display:column>

You can write your stuff within the tag like this:

<display:table id="row" >
    <display:column property="id" title="ID" paramId="id"  > 
        <a href="details.jsp?${row.id}">Details</a>
    </display:column>
</display:table>

Answer 4

You may have to be more specific in order to get better answers. Is the problem understanding struts2 or display tags? This tutorial expains how to create links in display tags library.

If struts 2 is the problem then you could make you question more specific and we'll see what we can do.

You could also create a decorator for the table and have it generate the link. See example below on some other forum: http://sourceforge.net/forum/message.php?msg_id=4119964
