By the way, on the t-deli page I saw the following:
Alternative base components
Version: 1.1
The If, Else, and For components provided by the Base library are similar to the Conditional and Foreach components that are a part of the Tapestry core distribution, but provide the following additional features:
* If the components are located in a Form, they automatically generate Hidden fields and ensure that the form will rewind as it was rendered and no stale link exceptions will occur.
The components can be viewed as a combination of the general Tapestry components (e.g. Conditional, Foreach) and their form-specific versions (e.g. FormConditional, ListEdit).
Maybe this is describing a similar issue?
