I am using Sencha Architect with Extjs 4
and by following the basic example here : http://geoext.org/tutorials/quickstart.html#basic-example
i have to switch included libraries from Ext 3 to Ext 4, so i typed :
<script src="extjs-4/ext-all.js" type="text/javascript"></script>
<script src="extjs-4/ext.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="extjs-4/resources/css/ext-all.css"></link>
<script src="GeoExt/lib/GeoExt.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="GeoExt/resources/css/geoext-all-debug.css"></link>
<script type="text/javascript" src="app.js"></script>
the problem is i keep getting errors which i think because missing library. but still can’t figure out what it is exactly.
Geo ext is compatible with extjs 3.x top, so doesn’t work with extjs 4.
You should check geo ext 2 sources, which is compatible with extjs 4.
