VF page is working properly but when I added a namespace, it suddenly showed this Null Exception error. Namespace name is bxc_markup, i prepended this name to the beginning of the controller name as shown on the 2nd line at the top, but its still the same thing. Could you help me find out what else do I need to do to fix the error? Again this only happened when I added namespace. There exception was thrown after the inner class was called.

Error when rendering:

  • can you include a debug of the error that you're receiving when the page loads - does the log give a more detailed error ? It would be helpful to see the error that you are receiving.

  • I added the debug logs. I'm am not that deep in VF so maybe i struggle with this one. Jan 18, 2018 at 4:57

    Most likely because you need to add the namespace to the get where you use markup_target_fields. You should always ensure a key exists before dereferencing. Debug the fields map to see what they keys are to help

  • The problem doesn't appear to be your VF page - but more appears to be in your controller - you should be sure that the values that you are using are existing here - such as "myId" -> does your page contain these parameters - do you have it at the time that getStrings is called? if not - every call after that where you try to reference something from Schema.getDescribe() you likely will be getting null reference here - be sure that you have a describeResult before trying to access methods of the describe result

Thanks for the comments!!!

I found out that of course, when namespace changes, it adds to the API name of the field set so I referenced the new API name of the fieldset now with the namespace prepended.

Thanks!
