Object Reference Not Set Error

I was doing an example on form extension.

The example includes creating a custom filter control on the MainAccount form.

I tried some of my own stuff, which went wrong. I received the following errors: "Object reference not set to an instance of an object. The menu item with name mainaccountdetails could not be opened."

1. I looked for the problem in my extension class. Could not find it.

2. Commented out all my code on the extension class for the form. No difference.

3. Deleted the extension class. No difference.

4. Deleted the extension form. No difference.

5. Deleted the project. No difference.

6. In visual studio d365 - model management - refresh models. Nothing.

So I still have the error. It would be great if someone can point me in a direction.

Sounds like the answer...

I'm gonna have to ask a stupid question: How do you build the base and extension package?

Thank you very much for the reply

Sukrut if you could look at another of my questions: determining a tree item type, I would be very thankful.

Hi Pete,

Even I have faced this issue few times. You should perform a build for your extension packages and reference packages in visual studio.

Build model option you'll get under Dynamics365 menu, from where you refreshed model parameters.

Thanks!

I built the Ledger package - no success. I am now building it with referenced packages (takes quite a while). Sukrut mentioned I should build the extension. Is there anything specific I should do to accomplish that?

have you checked that you completed your build successfully without any errors?

How ever in my previous reply, I have mentioned that you have to build reference packages as well. Build should complete without any errors otherwise if any error is there that is of no use, no changes you will find.

HI Pete ,

You can just select your extension package and base package from model parameters . select just check box and start build if you want selective package otherwise trying a full build is also option . Which other question (something with tree) you are talking about
