Version 4.5.0 example wt-home, how to stop multiple invocations after clicking browser "Reload Current Page"?

Added by jupiter hce about 3 years ago

Hi,

I added log messages to 4.5.0 wt-homepage, every time clicking the browser "Reload Current Page", it will increase calling createWtHomeApplication and created multiple WtHome:

It seems a bug but I could be wrong, how can I stop multiple instances when clicking browser "Reload Current Page"?

Thank you.

Kind regards.
