Component modification test failed (Resolved)

Hello
You are experimenting to understand how to make components.
For the moment I'm just trying to modify the existing ones
some work while others like the SR04 sensor that I am attaching
it seems to work, but when i try to save or load them
firmware the broswer file windows crash and I have to press esc.
I have not made major changes I do not understand what happens.

I found the problem was the call "widget-> update ();"
that creates this behavior I will look for something alternative.
