Undefined function 'xyz_dropdown' for input arguments of type 'matlab.ui​.control.U​IControl'. Error while evaluating UIControl Callback. --> Working in 2014b not working in 2018b anymore.

Hi Guys,

I have a question regarding the usage of programatic GUIs in Matlab.

Since I want to migrate a GUI from R2014b to R2018b I always get this error for several "UIControl"-Tools like dropdown, Pushbutton or edit fields.

All objects are defined and working as they should in R2014b.

Best regards,

JK
