Combobox & onselect / onchange action

[pbosman]

Hello all,

First of all, thanks for reading!

I'll go straight into the issue.
The basic question is how do I get my webapplication to call a method in my backingbean whenever my selection changes in my combobox. Sounds easy enough, but I've been getting head-aches for days now :(

Anyways, here's the code-snippet for my jsp page.

...
<rich:tab label="Skills">
 <h:panelGrid columns="2">
 <h:form>
 <h:panelGrid columns="2" id="addSkill">
 <h:outputText value="Selecteer Vaardigheid: " />
 <rich:comboBox directInputSuggestions="true" id="addSkillList"
 defaultLabel="Selecteer Vaardigheid..."
 value="#{sessionManager.toBeAddedVaardigheid}" required="true"
 width="250" onchange="#{sessionManager.toBeAddedVaardigheid}">
 <f:selectItems
 value="#{sessionManager.availableVaardighedenTable}" />
 </rich:comboBox>
 <h:outputText value="Kostprijs:" />
 <h:inputText value="#{sessionManager.teBetalenEp}"
 required="true" />
 </h:panelGrid>
 <h:outputText value=" " />
 <a4j:commandButton value="Add" id="addSkillButton"
 reRender="personageSelectionGrid, globalPanel, actionPanel, editPanel, deletePanel, loggingPanel"
 action="#{sessionManager.addSelectedVaardigheid}" />
 </h:form>
 </h:panelGrid>
 <h:panelGrid columns="1" border="1" cellspacing="5" cellpadding="2">
 <rich:messages style="color:red;"></rich:messages>
 </h:panelGrid>
</rich:tab>
...

The weird thing is that when I press my 'add'-button the setter method for the value linked to the combobox is fired.
However I wish for some way to fire 'a' method whenever the selection changes

any and all replies are appreciated!

regards,
Pieter

onchange - is a client side event handler and you seems just need a4j:support.

check basic samples.

Hey Ilya,

thanks for really fast response! Much appreciated!
Haven't checked the 'basic examples' you mentioned to be honest (you do mean anything I find using google I hope)

But I did try to add the <a4j:support ... /> thingie though:

...
<rich:comboBox directInputSuggestions="true" id="addSkillList"
 defaultLabel="Selecteer Vaardigheid..."
 value="#{sessionManager.toBeAddedVaardigheid}" required="true"
 width="250" onchange="#{sessionManager.toBeAddedVaardigheid}">
 <a4j:support action="onchange" ajaxSingle="true"/>
 <f:selectItems
 value="#{sessionManager.availableVaardighedenTable}" />
</rich:comboBox>
...

Yet this doesn't resolve anything.

Care to elaborate please?

Thanks in advance!

regards,
Pieter

Hi,
i think you have to replace:
<a4j:support action="onchange" ajaxSingle="true"/>
with
<a4j:support event="onselect" ajaxSingle="true"/>

Sure you can find usefull this page:

Gawd... 340 times I've read my code and 340 times I missed it completely... action instead of event...

Thanks a million Stefano!
