When I launch my App.mlapp I would like to insert in a numeric field the last value displayed before I close my App. But the field does not refresh and the new value does not appear. How can I do ?
function Test_App_Startup_CallBack(app)
clearvars –global;
load('C:\PQATestBenchNavigation\50 - Steering Wheel TestBench\defaultparameters.mat','testparameters');
global testparameters;
testparameters = importdata('defaultparameters.mat');
app.Fw_VersionEditField.Value = testparameters.fwVersion;

Issue can be in 2 things
1)App edit field not refreshing
I dont think this is the case
2) testparameters not getting updated?
can you try adding one line to get to know if testparameters has right value?
msgbox(testparameters.fwVersion)
If testparameters.fwVersion is not str
msgbox(num2str(testparameters.fwVersion))
Please check and let me know output of msgbox then we can debug further
