switch-case interaction with uigetfile

The following code seems straightforward. But the dialog box showing the files only appears briefly. It seems to be a condition associated with the switch-case construction because uigetfile works o.k. in testg.m outside of the switch-case.

The same action happened with uiopen.

Suggestion for a cure?

function [ ] = testg()

menu_choice = menu('Design Tools', 'Set Up Design File', 'Vehicle Aerodynamics');

switch menu_choice

    case 1
        [FileName, PathName] = uigetfile('*.mat');
    case 2
        disp('Aero!');

end

Oleg,

That is the whole code for testg.m. It was extracted from a larger function called design_tools.m.

Your code is working without any problems in matlab 2008b.

Paulo,

Thanks for checking the code in 2008b. Your result caused me to run testg.m in 2010a (which is as far back as I go). The problem occurs there, too. This suggests there is a bug in 2010b (and "a"). Do you agree?

[Eric]

I should add that when I run the code in the workspace it works.

[Paulo Silva]

Might be many things, please wait until more people test it.

[Oleg Komarov]

Is that the whole code you have in the function?

Put a breakpoint in menu() and experiment to see what is going on.
