In Tapestry 3, I have been doing something similar.
I use the following tags:
selected="ognl:submitListener" tag="ognl:listeners.onFinish"
which is part of:
<input jwcid="@Submit" label="ognl:page.visit.currentTasklet.finishLabel"
selected="ognl:submitListener" tag="ognl:listeners.onFinish"/>
This is at the page level. When the submit button is called, the formListener
is called and the abstract variable submitListener has been populated with the
listener "onFinish".
private IActionListener submitListener;
In my components I do:
<input type="submit" name="button" jwcid="@Submit"
selected="ognl:submitListener" tag="ognl:listeners.create" value="Create"/>
and I specify
private IActionListener submitListener;
So, when a button is pressed, either at the page or the component level only
one of these will be non-null.
What this means is that only one listener can be non-null so you can use that
as a flag for executing the rest of the formListener or not.
HTH,
Mark
