Re: T5 : how to handle a zone refresh when the user session has expired ?

I've written a small piece of code to reproduce the second emptyt:formdata hidden field :


<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<body>
   <t:form zone="myzone">
       <t:label for="field1"/> : <t:textfield t:id="field1"/>

<t:checkbox t:id="moreFieldsSwitch" t:mixins="triggerfragment"fragment="moreFields"/>

       <t:label for="moreFieldsSwitch">more fields ?</t:label>

       <t:formfragment t:id="moreFields" visible="moreFieldsSwitch">
           <t:label for="field2"/> : <t:textfield t:id="field2"/>
       </t:formfragment>

       <input type="submit"/>
   </t:form>
</body>
</html>

public class TestFragment {

@Persist @Property private String field1;

   @Persist @Property private String field2;

   @Persist @Property private boolean moreFieldsSwitch;

}

This results in the following XHR response seen in Firebug :

field1  test
field2  
moreFieldsSwitch        on

and the second t:formdata is a copy of the first one or is empty. Itseems to depend of the initial state of the fragment.

Very odd that you could end up with an empty t:formdata hidden field.

What is very strange is that there is 2 t:formdata in the XHR post : here is
the firebug post listing :

endDateSearch

Without the second empty t:formdata, i think that my zone would be updated
nicely ...

I get the following error when trying to refresh a Zone in my application
while the user session has expired :

org.apache.tapestry5.runtime.ComponentEventException
Forms require that the request method be POST and that the t:formdata
query parameter have values.

Any idea on how and where i can handle this exception to show the user a
better result than a blank zone ?

Thanks in advance.
