Problem with Ajax and injection with radio boxes

[kasim]

Yeah, i was wondering if anyone else had this issue and if there was a work around.

So basically.

I have a page with a bunch of inputs, i am using an Ajax call on a list box so when a certain list box is triggered it determines whether you need to select a radio box below.

The radio box is a string that i apply an @In annotation to it.

IT comes to the page disabled.

When i select a specific item it will enable the radio box. I go to select a radio button and submit it. However nothing gets injected.

Now here is the kicker, as i said it comes to the page disabled, if it comes to the page enabled and lets say you select somethign to disable, then go back to enabled it will WORK.

its only when you go to the page and the radio box is disabled initially does it fail.

Any ideas?? I can give some code if you need it but i am not sure if its a huge coding thing since as i said coming to the page enabled initially works.

Sure, Post the page

Ok here we go .... in the display page:

<rich:listShuttle sourceValue="#{customFlow.searchTypeList}"
 targetValue="#{searchTypesOrder}" var="item" listHeight="300"
 listWidth="300" sourceCaptionLabel="Available Items"
 targetCaptionLabel="Currently Active Items"
 fastOrderControlsVisible="false" orderControlsVisible="false"
 showButtonLabels="false">
 <h:column>
 <h:outputText value="#{item}"/>
 </h:column>
 <a:support event="onlistchanged" actionExpression="#{customFlow.test}"
 reRender="bondStereoPanel" />
</rich:listShuttle>

Which btw the action expression never seems to do anything, i even tried actionListener, neither call the server.

But ... the reRender calls ..

<a:outputPanel id="bondStereoPanel"> <h:selectOneRadio id="bondOption" class="style3"
 disabled="#{customFlow.stereoDisabled}"
 value="#{bondOption}">

<f:selectItem id="item1" itemLabel="Yes" itemValue="Y" />
 <f:selectItem id="item2" itemLabel="No" itemValue="N" />
 </h:selectOneRadio>
 </a:outputPanel>

.... then this is the bondOption

@In(required = false)
private String bondOption = "";

Dangit sorry about hte junky cut and pastign

Bind to a property like

#{controller.bondOption} - injection doesn't play well with JSF input controls.

Ok .. yeah i actually that done before.

Just to clarify though. I still will mark the bondOption with @In since i want to put it on a stateless session bean.

[pmuir]

Err. No. Make the bean stateful. What you are suggesting won't work afaics.

Just out of curiosity ... i thought the @In was specifically supposed to be used with input controls? I mean i guess you can inject other beans in there.

The rest of the code actually works, and this will even work as long as its enabled when one first goes to the page. Or am i misunderstanding what you mean by "jsf input controls"

[pmuir]

No, you need to use #{foo.bar} with input controls, otherwise a lot of JSF will break.

[kasim]

No, you need to use #{foo.bar} with input controls, otherwise a lot of JSF will break.

I changed the bean to Stateful .. and the same issue exists.

When the item is not initialized initially on the page the ajax call wont notice it when it gets enabled.

[kasim]

Pete - never mind ... as long as i initialize the value first it seems to be fine.

[kasim]

lol .... nope striek that ... it will never switch the value :(
