Hi!

After installing 2019a (had 2017b earlier) the appdesigner is no longer working. Buttons and stuff are missing in my old apps and also if I try to make new ones. The inspector panel is missing and I get the error:

Error using matlab.ui.control.internal.model.mixin.MultilineTextComponent/set.Text (line 49)

'Text' must be a character vector, a 1-D cell array of character vectors, a string array or a categorical array.

Error in matlab.ui.control.Button (line 51)

obj.Text = defaultText;

Error in appdesigner.internal.componentmodel.DesignTimeComponentFactory/createComponent (line 79)

component = feval(componentType,...

Error in appdesigner.internal.componentmodel.DesignTimeComponentFactory/createModel (line 17)

component = DesignTimeComponentFactory.createComponent(componentType, parentModel, peerNode);

child = obj.Factory.createModel(obj.getModel(),peerNode);

Yes, even examples or a blank app (with a button added), same problem. I'm thinking now that there is a clash with the old 2017b that I removed but kept the preferences and command history. I'll try removing all Matlab files and reinstalling.

Made a clean install of 2019a, but the appdesigner still doesn't work. When first started I got this message: "Unable to load individual component inspector cache".

Then, trying to add a button onto a new, empty app, I got the same message as before:

Error using matlab.ui.control.internal.model.mixin.MultilineTextComponent/set.Text (line

49)

As it turns out it was a lingering pathdef file that caused the trouble. When I deleted that (which had a 3rd party toolbox included) Matlab worked normally again, no problem with appdesigner anymore.

I suspect the 3rd party toolbox (PLS_Toolbox from Eigenvector, v 8.6.2) that I had installed for 2017b have functions that were clashing with 2019a.
