Using rendered="false" on an apex:selectOption element does not hide the option

Using the following visualforce markup, the second select option, which should not be displayed, is shown.

 

<apex:page>
    <apex:form>
        <apex:selectList size="1">
            <apex:selectOption itemLabel="test" itemValue="test" />
            <apex:selectOption itemLabel="don't show" itemValue="bad" rendered="false" />
        </apex:selectList>
    </apex:form>
</apex:page>
 
 Any ideas?

Does not seem to be possible to solve in VF. Guess you will have to provide this behaviour from the Controller

The documentation looks like it should work. 
 
https://na4.salesforce.com/apexpages/apexcomponents.apexp
 
apex:selectOption
 
Attribute name: rendered
Attribute type: boolean
Description: A Boolean value that specifies whether the component is rendered on the page. If not specified, this value defaults to true.
Api Version: 10.0
 
Can anyone at Salesforce shed some light on this? Is it a bug?

I'd like to know this as well. Did you open a case as I am about to?

TehNrd,
 
I did not open a case. I must have worked around the issue as I cannot remember why I needed it. Please let me know if you get it resolved through Salesforce.
 
Thanks! 


TehNrdTehNrd
I've submitted a case and will report back.

Apparently the bug was already submitted by someone but no ETA on a fix.

I remember how I worked around this. Instead of hard coding a selectOption under the selectList and using rendered="whatever" to show/hide the options, use selectOptions and apex to figure out which options should be shown. Does this help?


TehNrdTehNrd
Yup, that's what I ended up doing as well. It is just more work :smileytongue:

YES! This has been fixed in Spring 10! Now it is a little easier to do dependent picklists. Still have to hardcode, but at least no apex is required.
 
 
<apex:page standardController="Opportunity">
   <apex:form >
        <apex:selectList size="1" value="{!Opportunity.Name}">
            <apex:selectOption itemLabel="--None--" itemValue="none" />
            <apex:selectOption itemLabel="even" itemValue="even" />
            <apex:selectOption itemLabel="odd" itemValue="odd" />
            <apex:actionSupport event="onchange" reRender="dependent"/>
        </apex:selectList><br/><br/>
        
        <apex:selectList size="1" id="dependent">
            <apex:selectOption itemLabel="1" itemValue="1" rendered="{!Opportunity.Name == 'odd'}"/>
            <apex:selectOption itemLabel="2" itemValue="2" rendered="{!Opportunity.Name == 'even'}"/>
            <apex:selectOption itemLabel="3" itemValue="3" rendered="{!Opportunity.Name == 'odd'}"/>
            <apex:selectOption itemLabel="4" itemValue="4" rendered="{!Opportunity.Name == 'even'}"/>
        </apex:selectList>
    </apex:form>
</apex:page>
