Tabitha Syntax problem with ISPICKVAL
I'm trying to use ISPICKVAL to conditionally render part of my visualforce page. I want to show a pageBlockSectionItem if the value of Asset_Type__c is "Publications". Here is my code:
<apex:inputField required="true" value="{!Digital_Asset__c.Asset_Type__c}" />
<apex:pageBlockSectionItem rendered="{!ISPICKVAL(Asset_Type__c, 'Publications')}"><apex:inputField required="true" value="{!Digital_Asset__c.Publication_Title__c}" /></apex:pageBlockSectionItem>
The error I'm getting is:
Error: Unknown property 'Digital_Asset__cStandardController.Asset_Type__c'
I've also tried using {!ISPICKVAL(Digital_Asset__c.Asset_Type__c, 'Publications')} in the rendered block, but then I get: Error: Incorrect parameter for function 'ISPICKVAL()'. Expected Picklist, received Text.
What am I missing here?
I was able to use this syntax successfully:
<apex:pageBlockSection rendered="{!Digital_Asset__c.Asset_Type__c=='Publications'}">I still don't get why ISPICKVAL doesn't work, but this accomplishes what I was aiming for.

The latter is definitely the correct approach, it sounds as though Asset_Type__c isn't actually a picklist, I can't see any other reason as to why that would generate the error it is.
Additionally, one thing to be wary of is that sometimes using a boolean function in a rendered block doesn't work correctly (though it doesn't throw an error), you may need to do this as well:
rendered="{!IF(ISPICKVAL(Digital_Asset__c.Asset_Type__c, 'Publications'), true, false)}"Doesn't make much sense, I know, but there is a bug in there somewhere which means you sometimes require the IF.
Asset_Type__c is most definitely a picklist. I've tried it with the IF as well, and I still get the same error (Incorrect parameter for function 'ISPICKVAL()'. Expected Picklist, received Text).

Yeah that's pretty weird, sounds like some kind of bug to me. Glad you got it working though.
<apex:outputPanel rendered="{! ISPICKVAL(opportunity.Application_Group__c, 'Domestic')}"> Domestic Application Answers</apex:outputPanel>Returns “Error: Incorrect parameter type for function 'ISPICKVAL()'. Expected Picklist, received Text”
I thought it was a newb mistake of forgetting to put {! } around a Salesforce field, yet
<apex:outputPanel rendered="{! ISPICKVAL({! opportunity.Application_Group__c}, 'Domestic')}"> Domestic Application Answers</apex:outputPanel>Returns simply “Syntax error”
Tabitha’s workaround works (thank you!)...
<apex:outputPanel rendered="{! opportunity.Application_Group__c = 'Domestic'}"> Domestic Application Answers</apex:outputPanel>But I don’t like not knowing why something isn’t working (it’s my understanding that picklists require ISPICKVAL() or TEXT() functions to be used in formulas). As this is my very first Visualforce project I don’t know if it’s human error or mechanical bug. The field is definitely a picklist...
