Do you want to change the hyperlink on the column heading or the one
wrapped around the column's property?
For the property, using the latest displaytag, you have access to the
property, for example:
<display:table name="contacts" id="contactList">
<display:column>
<a href="/path"><c:out value="${contactList.name}"/></a>
</display:column>
This works splendidly, I tried it yesterday.
If you want to alter the hyperlink at the top of the column, the only
way I've found to do this was thing JavaScript. For instance, add the
following at the bottom of your table:
// get a tag of the 2nd column header and alter it to submit a form
// with JavaScript
table = document.getElementById("contactList");
a = table.getElementsByTagName("th")[1].getElementsByTagName("a")[0];
href = a.getAttribute("href");
// replace the action in the href, and then set it as the action
// on the form
href = href.substring(href.indexOf(".do"));
href = document.forms[0].action + href;
a.onclick=function() {
document.selectRows.action=href;document.selectRows.submit(); return
false };
I was successfully able to get my form to submit when clicking on the
column header, but I lost the ability to sort asc/desc on the table. I
then realized that the requirements did not call for the ability to sort
on this table and removed it altogether. ;0)
