listgrid groupby problems

[acarur01]

I have an invalidateCache/fetch logic that only works if the listgrid does not have grouping. If you run the testcase below using sample data in /isomorphic/system/reference/SmartClient_Explorer.html#dynamicGrouping, click on "test invalidate". You'll notice that the data is not fetched. I see this code working when one of two things is removed:

1. if I remove groupByField: "continent"
OR 2. if I remove isA.Tree(countryList.data) check

What's wrong here? Am I not allowed to call this function for grouped data?

isc.ListGrid.create({
    ID: "countryList",
    width:522, height:224,
    alternateRecordStyles:true, cellHeight:22,
    dataSource: countryDS,groupByField: "continent",
    // display a subset of fields from the datasource
    fields:[
        {name:"countryName"},
        {name:"government"},
        {name:"continent"},
        {name:"countryCode", title:"Flag", width:40, type:"image", imageURLPrefix:"flags/16/", imageURLSuffix:".png", canEdit:false}
    ],
    groupStartOpen:"all"

})


isc.Button.create({
title:"test invalidate",
left: 700,
click:function(){

if(countryList.data && isA.ResultSet(countryList.data) || isA.Tree(countryList.data)){
  countryList.invalidateCache();

}else{
  countryList.fetchData();

}
}
});

I'm using SmartClient Version: v8.2p_2013-03-04/PowerEdition Development Only (built 2013-03-04)

You haven't said what you're hoping this logic will do, but, when grouped, grid.data becomes a Tree. So your logic ends up calling invalidateCache() on a grid that has never fetched, hence has no cache, and nothing happens.

Yes, sorry I see what you mean. It makes no sense. Thanks
