Hi, I'm a new user of Tapestry. Looks great at first glance, but I'm
having some issues while trying to make a simple table. I can only find
snippets from Tapestry 3, so it's probably just a simple
misunderstanding of Tapestry 4's differences.
Specifically, each row of the table is a statistic on a file in a
particular folder. I'm generating these statistics once per deploy, and
creating a static Vector of POJOs, each representing a row of this
table.
I tried the following simplification, which should just render one row
and one column, but I got a Tapestry error: Unable to read OGNL
expression '<parsed OGNL expression>' of [EMAIL PROTECTED]:
epitopeItems.
Then I tried adding a <property name="epitopeItems"/> to my Home.page,
and I got a Hivemind error: "Either the tableModel parameter or both
source and columns parameters must be specified by component
Home/table.tableView".
What could I be doing wrong?
Home.html:
<html>
<head>

<body>
<table jwcid="table"/>
