Issue in rendering a field set dynamically
Hi,
I have the following code inside the repeat variable in the VF page:
<apex:repeat value="{!qa.getFieldsSetMemb}" var="ff" > <apex:outputField value="{!acc[ff.fieldPath]}"/> </apex:repeat>
where "qa.getFieldsSetMemb" returns "List<Schema.FieldSetMember>"
acc is the name of the account variable.
I am trying to dynamically display a field set in the above code.
While saving the VF page, I m getting the following error:
Error: java.lang.NullPointerException Error: null |
Any Idea?
Thanks

Hi,
Try the below code snippet as reference:
<apex:page standardController="Account">
<apex:repeat value="{!$ObjectType.Account.FieldSets.a}" var="f">
{!$ObjectType.Account.Fields[f].label}
<apex:outputField value="{!Account[f]}"/>
<br/>
</apex:repeat>
</apex:page>
Did this answer your question? If not, let me know what didn't work, or if so, please mark it solved.
Hi,
Please note that I am dynamically getting the field sets from the class. The following code hardcodes the field set name.
<apex:repeat value="{!$ObjectType.Account.FieldSets.a}" var="f">
{!$ObjectType.Account.Fields[f].label}
<apex:outputField value="{!Account[f]}"/>
Thanks

Good to know that you can get field sets in apex, I didn't know that. I suspect the issue is related to returning that field set from the controller/extension. Either it's not getting a field set, or maybe it's a timing issue that the page is loading and then those variables are being populated. Try pulling {!qa.getFieldsSetMemb} out of the repeat and displaying it right on the page just to see what's being returned. And if that's not it, do the same with {!ff.fieldPath}- display it inside of the repeat without the outputField. That should help you at least troubleshoot exactly where the issue is.
What does the controller code look like?
(Though if you are getting this error when you try to save the page definition, sounds like a bug...)
it means that the {!qa.getFieldsSetMemb} list is empty.....
make sure that the list contains the fields...(by a debug statement)
Make sure your controller code contain :
And in the page mark-up no need for qa.getFieldsSetMemb, if you have the above code in your controller...just {!qa} is enough
if it takes you to the solution, mark it as solution....
mapStudent : The map which stores all the records of the sObject.
map<string, sObject>
If this gives you solution , mark it as a solution
I have one requirement,
