In 4.0, component parameters have a default binding type. The default
binding type for the "selected" parameter is ognl:
http://jakarta.apache.org/tapestry/current/tapestry/ComponentReference/Submit.html
Try this instead:
<input type="submit" jwcid="@Submit" value="Cancel"
selected="whichButton" tag="cancel" onclick="form.onsubmit = null;"/>
It appears that Tapestry is trying to parse "ognl:whichButton" as an
ognl expression, instead of just "whichButton".
Confused? Me too. I was under the impression that "ognl:whichButton"
would still work...

I am getting an error message:
Unable to read OGNL expression '<parsed OGNL expression>' of
[EMAIL PROTECTED]: $UserAddPage_67.cancel
which highlights this line in my template:
<input type="submit" jwcid="@Submit" value="Cancel"
selected="ognl:whichButton" tag="cancel" onclick="form.onsubmit =
null;"/>
after I have pressed this cancel button.
In my page specification I have:
<property name="whichButton"/>
and in my java file I have:
public abstract String getWhichButton();
I used this technique in Tapestry 3.0 to determine which button was
being pressed.
Has anyone any ideas why this now fails and how to fix it.
Thanks in advance,
Paul
