I am converting a pre-existing webapp to use Tapestry 4.0. It uses
hibernate for the business objects and long's for the uid's on those
objects. I would like to use tapestry to coerce from the uid as a
string into the actual business object
Ultimately what I want to be able to do is to write a direct link like
this...
<span jwcid="@DirectLink" listener="listener:gotoDetails"
parameters="ognl:bizObject">view details</span>
public void gotoDetails( BizObject bizObject ) {
// rest of code goes here
}
instead of how I am currently doing it as follows...
<span jwcid="@DirectLink" listener="listener:gotoDetails"
parameters="ognl:bizobject.uid">view details</span>
public void gotoDetails( Long uid ) {
BizObject bizObject = DAO.getBizObject( uid );
}
I know I need to use the tapestry.coerce.ValueConverter service. Can
anyone point me in the right direction as to how I would implement this?
