Ok, thanks for that. Added property to page to store Thing. No more error, but, now it seems as if the page is being rendered without regard to the <t:parameter> tag. It is completely ignored and the grid is rendered as if the parameter tag is not even there, in other words, no link is created. View source, just standard table and text, no link tag.
Thanks for your help in advance. -----Original Message----- From: Davor Hrg [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 17, 2007 13:53 To: Tapestry users Subject: Re: Using row param in grid you must create a property to store current row (for example "thing") getThing and setThing .. and change your template: <t:grid t:source="thingList" row="thing"> <t:parameter name="name"> <t:pagelink page="Start" context="Thing.name">${thing.name}</t:pagelink> </t:parameter> </t:grid> the concept here is that you give list of objects to grid with source= from which grid reads data for the loop. but the row= tells the grid where you want to store the current value which is where grid writes data. I'm not explaining this very well, but "binding" is a basic tapestry concept.
