How to limit the # of characers displayed in an outputField?

I have a requirement to limit the # of characters displayed in an outputfield.  If the field value is > 100 characters, the displayed text should be truncated.  As shown below, I tried to use 'left' to limit the characters to 100, but I recieve the following error:

 

"Error occured trying to load the template for preview: value for outputField is not a dynamic binding!. Please try editing your markup to correct the problem."

 

Can I accomplish this in VF without using a controller? 

 

<apex:outputField value="{left(!cx.match_criteria__r.searcher__r.account.Investment_Focus__c,100)}" />

so this is what i tried and it's working

 

 

<apex:page standardController="account">
  <apex:outputText value="{!LEFT(account.name,12)}"></apex:outputText>
</apex:page>
 
 looks like you don't need outputField , can you use outputText?

i think you can, change the {! location like this: 
 
 
<apex:outputField value="{!left(cx.match_criteria__r.searcher__r.account.Investment_Focus__c,100)}" />

Thanks Ron! 
 
I am recieving the following syntax error, but only when using the code you provided:
 
Error
Error: Syntax error. Missing ')' 
 
What do you make of this? 
 
Thanks,

Thanks Ron!
 
I don't understand why it should make a difference...but when I changed from <apex:outputField> to <apex:outputText> I no longer recieved the error.
 
Can you help me (us) understand why?

output field is a much more complex tag, it will bind it's value to a very specific field of an sobject. 
 
output text is simpler, and will bind to the output of an expression or field value.

It is worth noting that the message: "value for outputField is not a dynamic binding!" can occur:
 
  • When you don't use an ! immediately after the left curly bracket '{'.  In your example, the ! should appear before the 'l' in the function 'left'.
  • <apex:outputField value="{left(!cx.match_criteria__r.searcher__r.account.Investment_Focus__c,100)}" /> 
     
  • If you forget to include a closing '}' such as in this expression (no '}' after the final paren and before final double quote):
  • <apex:outputField value="{left(!cx.match_criteria__r.searcher__r.account.Investment_Focus__c,100)"

value for outputField is not a dynamic binding! 
 
Possible reason: missing {! ............. } braces for the expression.
 
<apex:pageblocktable id="table1" value="{!lstMyLiveIOs}" var="obj" >                  
          <apex:column headerValue="Booked Quantity">
                 <apex:outputField value="obj.FB_Quantity__c" />
          </apex:column>
</apex:pageblocktable>
 
Correct syntax is:
<apex:outputField value="{!obj.FB_Quantity__c}" />
