i do have a buffered store (infinite scrolling with >10.000 records).
so far it works fine as long there are records in the store.
if there are no records i get the exception
Code:
"Uncaught Ext.Base.getRange(): PageMap asked for range which it does not have"
examining the source
Code:
        getRange: function(start, end) {
            if (!this.hasRange(start, end)) {
                Ext.Error.raise('PageMap asked for range which it does not have');
            }
leads me to the thought, that an empty result from the server - no records - could never have a start or an and.
is this a bug or is there a workaround for it or is there something i just don't know about the new usage of an infinite scrolling grid?

please help. stuck with this problem around two weeks now :-(
