SuggestionBox doesn't support many-to-many objects?!?!

[derkd]

Hi all,

I want to load some entities from my DB which has a many-to-many relationship in a rich:suggestionBox. The strange thing is that I got an Servlet execution exception.

Let me explain by code (I have removed the hibernate code and replaced it with simple objects):

this is my suggestionAction:

{code}public List<Profession> professionAutoComplete(Object auto) {
log.debug("professionAutoComplete: " + auto.toString());
professions = new ArrayList<Profession>();
Profession p = new Profession();
p.setId(new Long(1));
p.setTitle("test profession");
p.setDescription("blaaa");
ProfessionGroup pg = new ProfessionGroup();
pg.setId(new Long(1));
pg.setTitle("professiongroup");
pg.setDescription("lbaaaaaa");
//          pg.getProfessions().add(p);
p.getProfessionGroups().add(pg);
professions.add(p);
return professions;
}{code}

Above code works, but if I uncomment the

{code}//          pg.getProfessions().add(p);{code}

I get the exception:

{code}Exception during request processing:

Why can't I use an object with a many-to-many relation?

Hi Derk,

Looks like you've posted not a complete stack trace. Please post the part with real exception cause.

[derkd]

Hi Nick,

Yes that's the strange thing, there isn't anymore. The exception I already posted is from the seam.debug but in the server.log of jboss there isn't any exception

[derkd]

Nick,

Did you had the time to reproduce it? I think it is a bug in RichFaces because when I remove the

{code}p.getProfessionGroups().add(pg);{code}

It works!! But I need that relationship

Regards,

Derk

Derk,

Is 'usingSuggestObjects' set to true?

[derkd]

Hi Nick,

Thanks for your quick reply. Yes the 'usingSuggestObjects' is set to true:

{code}<s:decorate id="professionField" template="/layout/edit.xhtml">
              <ui:define name="label">Profession:</ui:define> 
          <h:panelGrid columns="2" border="0" cellpadding="0" cellspacing="0">
            <h:inputText id="professionInput" style="margin:0px;" />
            <h:graphicImage value="/img/icons/arrow.png"
                    onclick="#{rich:component('suggestion')}.callSuggestion(true)"
                    alt="" />
          </h:panelGrid>
            <h:outputText value="Professions" />
            <h:outputText id="objects" style="font-weight:bold" />
          <rich:suggestionbox height="200" width="200" 
            usingSuggestObjects="true"
            onobjectchange="printObjectsSelected(#{rich:element('objects')}, #{rich:component('suggestion')});"
            suggestionAction="#{professionHome.professionAutoComplete}" var="_profession"
            for="professionInput" fetchValue="#{_profession.title}" id="suggestion" tokens=",">
            <h:column>
                <h:outputText value="#{_profession.title}" />
            </h:column>
            <h:column>
                <h:outputText value="#{_profession.description}" />
            </h:column>
            <a4j:support ajaxSingle="true" event="onselect">
            <f:setPropertyActionListener value="#{_profession.id}" target="#{professionHome.professionId}" />
        </a4j:support>
                      </rich:suggestionbox>  
               </s:decorate>{code}

Please check this issue: https://jira.jboss.org/browse/RF-4903

[derkd]

Hmm ok so indeed it is a bug. Thanks for the clarification!

This issue is fixed in 3.3.4.BETA and ENT_3.3.3.SP1, do you know when this will be released?

[ilya_shaikovsky]

As for 3.3.4 community branch - we have no plans for future releases. All our efforts - targetted to 4.x. So using 3.3.4 snapshot seems the only way.

And the second fix version related to Jboss product and not for community project. RichFaces ENT_3.3.3.SP1 is a part of Jboss WFK

[derkd]

Hi Ilya,

Thanks for your reply. That's too bad that there won't be an 3.3.4 or SP1

4.0 isn't backwords compatible with JSF 1.2 right?

So I will need to use the 3.3.4 snapshots I guess.

Regards,

Derk

You can use workaround mentioned in JIRA.
