Hallo,
I would like to populate a client only datasource (clientOnlyDS) from a databound RestDataSource (boundDS) und use clientOnlyDS as source for a grid.
Here is my simple testcase:
where my test data (data.xml) looks like this:
In Hosted mode the grid is populated without any problem. But if I compile the code and try it in the browser, the grid is drawn, but stays empty, saying "loading data ...". According to firebug, data.xml is loaded but the grid doesn't fetch its data. This happens even, if I put grid.draw() at the end of onModuleLoad(). The problem occurs in Firefox 3.5.5 as well as in IE 8.
Where is my mistake?
