Migration ExtJS 4.2 to ExtJS 6.0.1

• Add the meta tag in the HTML main page (done by plugin_dbui)

    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />

• Use the following construct with HTML pages containing javaScript, e.g. version, report_4:

        <script>
            var mydict = {{=XML(json.dumps(my_python_dict))}},
                mystr = '{{=my_python_str}}';
            ...
  
        </script>

• Check the event select for ComboBox. Signature has changed records become record.

• In the column configuration of the grid widget use columnWidth instead of flex. In principle both are working, but some issues appeare with the second one when unmasking hidden columns.

• in app.js replace the Ext.EventManager by:

    // Close user session on the server.
    Ext.getWin().on('beforeunload', Dbui.closeUserSession);

• Use the script build-version6 to compile your JavaScript libraries. The script is in the project w2pext/utilities.
