Running an older version of app designer in a new one
7 views (last 30 days)
I have an app created in App Designer with the version R2021a. When I opened my app today, the following message appeared: "This app was created in MATLAB R2021a. The generated code has been updated for R2021b". When I try to run the app, it takes a long time and at the end it does not appear. In the command prompt of Matlab appears the following message: " Warning: Graphics timeout occured. To share details of this issue with MathWorks technical support, please include that this is a graphics handshaking issue with your service request" (I am attaching an image of this message, "graphic_problem"). And now when I open the app, the component UIAxes plot does not appear in the canvas and when I try to add a new UIAxes component this message appears: "Unable to add component matlab.ui.control.UIAxes. Component creation failed with error: Unrecognized method, property or field 'ServerID' for class 'matlab.graphics.primitive.canvas.JavaCanvas" (see the image "error creating UIAxes").
Do you have some idea what to do?
Thanks in advance for your comments!
