Do you have all the same add-on modules in v8.1 ? And they all loaded? Any hints about that would be in the client debug console.

3

Also, screen shots are generally unhelpful when it comes to error stack traces and code, try as I might I just cant scroll down to see all of the stack. :wink:

Copy the entire error and paste it into a preformatted text block.

Hint: click the </> button or use Ctrl + Shift + C to insert a preformatted text block.

All modules work fine, the window won’t open in the designer and client

With the full error it looks like it is having issue with a BusylabelComponent

Caused by: java.lang.ClassNotFoundException: com.byesapps.busylabel.client.BusylabelComponent

Did the 7.9 server have a third party module installed? Have you installed the correct version of that module?

6

The root cause is this:

Caused by: java.lang.ClassNotFoundException: com.byesapps.busylabel.client.BusylabelComponent

Which seems to be a reference to a 3rd party component that is not found for some reason. I’m guessing you do not have the new 8.x version of this module; it certainly wouldn’t be part of our installer.

7

Its true, is there any way to remove it?

8

Open your projects in 7.9, and remove the busy label, then re-import.

If you still need something to replace it:
