GUI Opening Error: Struct contents reference from a non-struct array object.

Hello,

i searched for different answers, but mine is a bit different then the other Threads. Anyway i cannot open my App in App-Designer without getting the

ERROR: Struct contents reference from a non-struct array object.

straight from the beginning when it starts loading the app in app designer.

From matlab itself as a command >>APP1 theres no error and the app works fine ...

Was the APP1 created with App Designer?

[pb93]

yes

[Thomas Swindle]

Exact same issue here. I've been developing an app for over a month and now I can't even open the code in matlab. This is frustrating.

Could you give us the full copy-pasted error message (all of it)?

Just to rule out some basics, could you give us the result of

which appdesigner -all

and your matlab version
