[jira] Commented: (TAPESTRY-630) PropertySelection "listener" parameter does nothing

Kevin J. Menard, Jr. commented on TAPESTRY-630:
-----------------------------------------------

Then it should not complain if you specify a listener parameter but don't provide a listener as a value.  It should treat it as it would any other informal parameter.  Should I open another bug for this?

> 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.
