Errors in app designer after installing 2019b

Hello,

I have installed 2019b a few days ago (from 2018a), and now I have trouble working with the app designer.

For example, if open a new blank app, and simply drag and drop an axes component on the canves, I immediatly get the following error messege (in the command line):

Undefined function 'isvalid' for input arguments of type 'double'.

Thanks, it worked.

However it's pretty anoying that pause on error has to be disabled when working with the app designer. Is this bug expected to be fixed soon?

[Ijab Zhan]

Yes Tom, it will be fixed in Update 3 based on my knowledge.

Hello,

can you please guide how to disable pause on error for app designer?! I tried 'dbclear if error' and also 'dbclear all' command in command space and then opened appdesgner from there; it didn't work. Also in code view of appdesigner no debugging option is there to disable breakpoints. Please help.
