Re: [flexcoders] Difficulty updating Grouping in Advanced DataGrid

[Tom McNeer]

Okay, I'm back already.

Here's what I don't understand: I'm using an ArrayCollection as the dp to a
GroupingCollection -- and I know that GroupingCollection subclasses
HierarchicalData.

Instead of subclassing HierarchicalData directly, should I subclass
GroupingCollection, with the same overridden methods?

Here's what I'm working with:

           <mx:GroupingCollection id="divGrouping"
source="{acJobsInProgress}">
                <mx:Grouping>
                    <mx:GroupingField name="DivisionTypeName">
                      <mx:SummaryRow summaryPlacement="group">
                        <mx:SummaryField dataField="BudgetItemTotal"
                                label="Cum Ttl" operation="SUM"/>
                      </mx:SummaryRow>
                    </mx:GroupingField>
                    <mx:GroupingField name="Estimator">
                      <mx:SummaryRow summaryPlacement="group">
                        <mx:SummaryField dataField="BudgetItemTotal"
                                label="Cum Ttl" operation="SUM"/>
                      </mx:SummaryRow>
                    </mx:GroupingField>
                    <mx:GroupingField name="JobName" >
                      <mx:SummaryRow summaryPlacement="group">
                        <mx:SummaryField dataField="BudgetItemTotal"
                                label="Cum. Total" operation="SUM"/>
                      </mx:SummaryRow>
                    </mx:GroupingField>
                </mx:Grouping>
            </mx:GroupingCollection>
