I am in the process of upgrading from Tapestry 3 to Tapestry 4 and am
having problems with one of my pages.
The page in question uses a @ListEdit defined as so using the
Tapestry 3 DTD:
<component id="measurementList" type="ListEdit">
<binding name="source" expression="listEditMap.keys"/>
<binding name="value" expression="listEditMap.key"/>
<binding name="listener"
expression="listeners.doSyncMeasurementItem"/>
</component>
The listener is defined as so:
public void doSyncMeasurementItem(IRequestCycle cycle) {...}
However at runtime the listener is never being called! And no error
is being logged that it can't find one. This page works fine under
Tapestry 3. The result is that when the page tries to reference a
value that should have set by the listener, a null pointer is thrown.
The documentation for @ListEdit does state that @ListEdit is being
depreciated but definitely implies that it is supported in 4.0. But
it also does not state if the listener signature should be something
else.
Any pointers on where to look for a solution would be appreciated.
