Yes, Thing has a property of name. Not using a custom model. Tapestry sees the Thing and knows it has 'Name' and 'Size' columns, because it constructs the grid with those column headers and puts the correct values in each column. I just want to tell it to put a link in the 'Name' column. That is all. Seems ever so simple. But, although it knows that Thing has a name property, it is ignoring the <t:parameter name="name"> tag. I have even tried taking out the pagelink tag and putting in alternative text. The <t:parameter name="name"> tag is completely ignored still.
