[solved] Simple application with json loading

Hi

Before 17.10, i used to make application like this :

an html file with

<script type="text/javascript" src="b4w.min.js"></script>

an js file with

m_data.load("myfile.json", load_cb, preloader_cb);

can't make it works now, got always a blank page., without specific error, no matter the json file

any idea?

[EDIT] cache problem
