Callback error; attempt to index a nil value

[Anonymous]

hi all,

I have been trying to create a Panel for my Emu E4. I’ve been using the Emu V1.2.6 EOS control Demo.panel as a starting point.
I have been trying to connect all the UI components with the Hardware via SysEx generally with success. (Using http://www.deepsonic.ch/deep/docs_manuals/e-mu_eos_remote_sysex.pdf as guide)
All of the sudden i am getting this error and cant select any preset:

Callback error; panelMidiReceived
At line [1670]..... attempt to index a nil value

I attached a Screenshot.
Couldnt find any post/thread with this specific issue.

What have i done wrong?
Would this be because a certain preset has to be actually Selected first?

I would like to build my own preset manager but im struggling to understand how to display text(?what ui component do i use?) i tried everything!
If i start a fresh template using SysEx only when i try to modulate/control any parameter, the EMU does not respond(even tho i know the SysEx formula is correct).

Apologies for the double question.
Any help very much appreciated!! noob here.

have a look at line 1670 in your method and see what it is
that … the other guys will explain this better … i equate
it with not having declared something adequately. i’m still
a bit woolly with it all, but that’s why i get those messages.
you may have multiple issues there, it’s stopped at the first
error.

I figured it out.
At the line in question was a reference to some disabled controls which i deleted.

Callback Error FIXED!

How about the second part of my question;
How can i display text thats coming in via SysEx? uiLCDLabel does not have a SysEx ability. I’ve tried them all.
