Subject [jira] Updated: (TAPESTRY-630) PropertySelection "listener" parameter does nothing
Date Sat, 10 Sep 2005 14:33:30 GMT

Kevin J. Menard, Jr. updated TAPESTRY-630:
------------------------------------------

    Attachment: testcase.zip

It may very well be the case that I'm doing something wrong, but I'm pretty sure I'm not.
 I've attached a test .html and .java file (with annotations) and the exception page from
Tapestry.  Due to not having my selection model and different package structure, you won't
be able to run these as are, but they're small enough to illustrate the issue.  Please let
me know if you need anything else.

> The formal "listener" parameter for the PropertySelection listener seems to not do much.
 Specifying the parameter but not having the actual listener method will generate an error
as expected.  However, if a listener is supplied, it is simply never called.  I tested this
by setting onchange="javascript:this.form.events.refresh();" and onchange="javascript:this.form.submit();"
(I did not try this.form.events.submit() since there is a bug with that not actually submitting
currently).
> Anyway, it would be nice if the listener would get called.  Changes to PropertySelection
components are often used to update form contents.  Another nicety would be if specifying
a listener automatically provided an onchange value.
