I want to display a button but only when two fields are matched (Category__c = Events & Custom_URL__c IS NOT BLANK).

<apex:outputLink value="/register" id="register" rendered="{!IF(AND(article.Category__c == 'Events', NOT(ISBLANK(article.Custom_URL__c))), TRUE, FALSE)}">
Register
</apex:outputLink>

But on items where Custom_URL__c is populated (with a URL) the link is still not shown.

I have done SOQL query to see what data is being recieved and the Custom_URL__c field is clearly populated in the record.

  • Have you tried reducing your condition to {!NOT(ISBLANK(article.Custom_URL__c)} to verify that it is just the URL part that is the issue? – BarCotter Jan 27 '15 at 10:50
  • I have yes, it is still not working – Deployment Failure Jan 27 '15 at 10:52

    Add an apex:outputText element to test out your formula. Start with a simple output such as <apex:outputText value="{!article.Custom_URL__c)"/> or <apex:outputText value="{!'URL:' & article.Custom_URL__c)"/> and then keep adding to it each time to verify the output is as expected. – BarCotter Jan 27 '15 at 10:59
  • The field was not shown, this leads me to believe the field is not visible under the current profile. – Deployment Failure Jan 27 '15 at 11:21
  • That would cause that type of problem alright. – BarCotter Jan 27 '15 at 11:22

The best way to debug these types of issues is too start with the simplest formula/condition and display it in an apex:outputText element. In your case you could start off with:

<apex:outputText value="{!article.Custom_URL__c)"/>
// OR this
<apex:outputText value="{!'URL:' & article.Custom_URL__c)"/>

You can then verify that the output is as you expected. Then add more and more to the formula, while checking the output as you go along.
