Tapestry5SelectObject problem with Tomcat - selection is not persisted
Hi,
I have a problem with submitting selection from list box when the
application is deployed on Tomcat, while it works correctly in Jetty and
Glassfish.
The selection lists are implemented like in:
http://wiki.apache.org/tapestry/Tapestry5SelectObject
Here is the snippet of code:
<t:form t:id="planSelectForm">
<t:selectObject t:id="selectPlan" list="planList" value="selectedPlan"
labelField="literal:title" blankLabel="All" onChange="form.submit();" />
</t:form>
This should refresh a grid that looks like this:
<table t:type="grid" t:source="programs" t:row="programGrid" t:exclude="programId" t:add="literal:delete">
The relevant code behind looks like this:
@Persist
@Property
private Plan selectedPlan;
public List<Program> getPrograms() {
if (selectedPlan == null)
return ....;
else
return ....;
}
So the form.submit() works and the page refreshes, but it seems like the
selection has not been persisted and this happens only on Tomcat (6.0.18
if that matters).
As I mentioned in another message, everything works perfectly in Jetty,
and I have UTF problems in Glassfish, and this problem in Tomcat.

It could not be the cause of your specific problem now, but initializing
fields in their declaration causes one user to see information from other.
Never do that.

Did I mention I was using Spring and Spring Security? There filters were
possible messing with UTF-8 requests from browser and I found the
following solution on several Spring forums, so I mention it also here
just for reference.
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

This was not the problem because I had several different cases.
In fact after lot's of debugging it turned out that the problem is again
the same as in my other post - bad UTF received from browser after
selecting an option.
The selection boxes were in fact coded with cyrillic character codes
which were received incorrectly from the browser.
So once again I had the same problem, although Tapestry is supposed to
work entirely in UTF-8, it does not, and depending on server it receives
broken input.
I tried setting JAVA_OPTS="-Djavax.servlet.request.encoding=UTF-8" but
it doesn't help.

Never initialize a Tapestry page field. Use some event handler method to
do that.

Tried this and this does not help.
The selectobject component is backed by this:
@Property
private List<Plan> planList = new ArrayList<Plan>();
And Plan is an @Entity backed by Hibernate with equals and hashCode
implemented based on the primary key.

This kind of error is typically cause by lack of proper equals() and
hashcode() methods in the class that is put in a colletion.

Just to add, I have the same problem with Jetty setup behind IIS with AJP13.
Then it might be related to how the filter works. The object
selectedPlan stays to null after selection and refresh.
Anyone any ideas?
