I ran across an issue with the Glide designer where I would click the “Show XML” menu item and nothing happenned. At first I couldn’t reproduce it, but then I realized that since this is XML, it might not be legitimate for me to use “< Back” for the .Text of a Button.
Sure enough, that was it.
On the API side too - if you manually edited one of your windows to include a < or > you get an XML parser exception.
So looking back, that exception is expected - but the Glide designer fails silently. Just FYI…
