VF page modified with slds markups return an "Attempt to de-reference a null object" error when trying to save
Hi,
I have a VF page running in Lightning that save and cancel perfectly. I have modified it with slds markups to look likes Lightning and now when I try to save the record I got an error message "Attempt to de-reference a null object".The cancel button still works.
Any thought?
Shorten codes are as follow:
VF Page that works
VF Page that does not work
Same APEX Controller
Thanks,
Sylvie

You've used 3 if conditions from the line 38 to 42. and assigned the record type id in FF.RecordTypeId.
The reported issue is due to Null value is assigning to the FF.RecordTypeId ie) the above condition doesn't satisfied.
And Please use 48th line inside Try block.
Thanks in Advance.
Thank you for your answer. Sorry but I do not understand what you mean. The if conditions works perfectly in the basic VF page the Record type id is allocated depending on the VF page name. But with the same page with SLDS markup it stop working and give me a null object error. It is exactly the same Apex class and VF page the only think that change is the SLDS styling. How can that impact the if condition?
Could you also please tell me what do you mean by use Try block?
Thanks,
Sylvie
