Form submission fails only after the 1st time, T4.1.3 bug?
I am facing this strange behaviour if Tapestry 4.1.3:
I have a form, declared in the .page as:
component id=quoteForm type=Form
binding name=listener value=listener:quoteSubmit/
binding name=delegate value=beans.validationDelegate/
binding name=method value='get'/
binding name=success value=listener:quoteSubmit/
/component
In the .xhtml file, I place a PropertySelection component (model and value
are ok).
component id=selectCountry type=PropertySelection
binding name=model value=countrySelectionModel/
binding name=value value=selectedCountryId/
/component
The problem is that I want to submit the form when the user changes the
value of the drop-down list.
Till Tapestry 3.0 -- as far as I'm aware of -- there was a
submitOnChange=true that worked fine.
How can this be done in Tapestry 4.1.*?
I tried writing
onchange=javascript:this.form.submit(); at the PropertySelection component
select jwcid=selectCountry onchange=javascript:this.form.submit();
but it only works once(!). What I mean is that the first time the user
selects something, everything works, the form gets submitted and the page
gets refreshed.
When I try for the second time, I get a blank screen without any debug
message and sometimes (after small modifications) the The connection to the
server was reset message! Shouldn't Tapestry produce some kind of a
warning?
The listener code is
public IPage quoteSubmit(IRequestCycle cycle) {
System.out.println(SelectedCountryId: + getSelectedCountryId());
System.out.println(nkons Debug check QUOTE_SUBMIT +
getSelectedSubmitComponent());
if (QUOTE_SUBMIT.equals(getSelectedSubmitComponent())) {
.
return some_other_page;
} else {
this.setSelectedLocationId(null);
return this;
}
The application server is jboss 4.2.1
I would appreciate any ideas

Hello,
javascript: is not needed, just
onChange=this.form.submit();

Re: Form submission fails only after the 1st time, T4.1.3 bug?
Hello,
I managed to solve it. The problem was the line at the listener:
this.setSelectedLocationId(null);
that was setting the selectedLocation to null. Why I asked before was
because I was facing a behaviour without any produced messages, so I didn't
know where to begin. In the beginning of the listener I had a
System.out.println(SelectedCountryId: + getSelectedCountryId());
that wasn't printing anything (not even a null exception).
I found the solution ad hoc after all but anyway, thanks for the quick reply
