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
