The clue's in the documentation
(<http://displaytag.sourceforge.net/11/displaytag/tagreference.html#column>)
href: The *base* URL used to construct the dynamic link. If this
attribute is provided, then the data that is shown for this column is
wrapped inside a <a href=""> tag with the url provided through this
attribute. Typically you would use this attribute along with one of the
struts-like param attributes (param*) to create a dynamic link so that
each row creates a different URL based on the data that is being viewed.
An empty href value will generate a link to the current page, preserving
parameters just like for paging links.
If your actionCmd property is the entire url then you'll be better off with:
<display:column sortable="true" title="${isisQuery.colHeader1}"
headerClass="isis">
<a href="${row.actionCmd}">${row.primaryKey}</a>
</display:column>
Ed!
