[SalesForce] Help text does not appear

I don't know why, but the help text and the helptextimage does not appear.

    <apex:pageBlockSectionItem helpText="{!$ObjectType.Opportunity.Fields.StageName.inlineHelpText}">
         <apex:outputLabel value="{!$ObjectType.Opportunity.Fields.StageName.label}" />
         <apex:inputField value="{!oppString.StageName}" />
     </apex:pageBlockSectionItem>

Any ideas?

Make sure ShowHeader="true" in your page definition, as mentioned in this forum post: https://developer.salesforce.com/forums/?id=906F000000097KUIAY

This is working in my dev org:

<apex:pageBlock>
<apex:pageBlockSection title="Sample Section">
<apex:pageBlockSectionItem helpText="{!$ObjectType.Opportunity.fields.Amount.inlineHelpText}">
             <apex:outputLabel>{!$ObjectType.Opportunity.fields.Amount.Label}</apex:outputLabel>
             <apex:inputField value="{!Opportunity.Amount}" />
       </apex:pageBlockSectionItem>
</apex:pageBlockSection>
</apex:pageBlock>
