[FIXED-391][3.0.3] Grid doesn't save grouping state

[durlabh]

Refer to thread:
http://www.extjs.com/forum/showthread.php?t=26963.

This needs to be fixed in trunk too:



Ext.override(Ext.grid.GridPanel, {
applyState : function(state){
var cm = this.colModel;
var cs = state.columns;
if(cs){
for(var i = 0, len = cs.length; i < len; i++){
var s = cs[i];
var c = cm.getColumnById(s.id);
if(c){
c.hidden = s.hidden;
c.width = s.width;
var oldIndex = cm.getIndexById(s.id);
if(oldIndex != i){
cm.moveColumn(oldIndex, i);
}
}
}
}
if(state.sort){
this.store[this.store.remoteSort ? 'setDefaultSort' : 'sort'](state.sort.field, state.sort.direction);
}
if(state.group && this.store.groupBy){
this.store.groupBy(state.group);
}
},
getState : function(){
var o = {columns: []};
for(var i = 0, c; c = this.colModel.config[i]; i++){
o.columns[i] = {
id: c.id,
width: c.width
};
if(c.hidden){
o.columns[i].hidden = true;
}
}
var ss = this.store.getSortState();
if(ss){
o.sort = ss;
}
if(this.store.getGroupState){
var gs = this.store.getGroupState();
if(gs){
o.group = gs;
}
}
return o;
}
});

This is a feature request and not a bug.

Also, I don't like the solution, because it puts grouping related code in GridPanel.

Instead, GridPanel should forward the getState and applyState methods to the view, so GroupingView can get/apply the grouping.

[durlabh]

I agree with Condor. At this point, getState and applyState get the state info from the store. Same ways, columnModel state is being retrieved/ applied from within GridPanel. However, these should be responsibility of the gridView and columnModel. This way, view and columnModel will not be that tightly coupled with the gridPanel itself.

Well, technically yes, but the ColumnModel and the GridView ~are~ tightly coupled with the grid, the only reason to include the extra complexity is for possible subclasses to push extra properties onto the state object.

[durlabh]

In that case, I consider this a bug as it is fixed in 2.x branch. Can you please fix in 3.x branch too.

Fix applied to svn in rev #5790 for patch release 3.2.
