URL: https://github.com/apache/royale-asjs/issues/936
Looking at the Tour de Jewel "Column Swapping" example, the DataGrid toggles
columns by splicing DataGridColumns initially instantiated in the markup.
Based on this, I've tried to implement dynamic DataGrid columns by creating
an array of DataGridColumns objects programmatically and then assigning an
array of them to Datagrid.columns ... The columns, unfortunately, do not update
and I wonder if I am missing something (is there some Bead I need to add)... or
is this currently not possible? The DataGrid data provider updates, but only my
dummy column remains...
```
<j:DataGrid id="ListTable">
<j:beads>
<j:RemoveAllDataGridItemRendererForArrayListData/>
<j:DataGridColumnLabelsChange/>
<js:ConstantBinding
sourceID="tablesModel"
sourcePropertyName="tableData"
destinationPropertyName="dataProvider"/>
</j:beads>
<j:columns dragEnabled="true" allowMultipleSelection="true">
<!-- I included 1 dummy column initially, but this will
be replaced with dynamically generated colums-->
<j:DataGridColumn label="Dummy" dataField="dummy" />
</j:columns>
</j:DataGrid>
...
// The following attempts to update the Datagrid columns, but doesn't work...
// However, if I log ListTable.columns I see the change, the Datagrid itself
just doesn't seem to update the
// columns even after I have successfully refreshed the dataprovider..?
var col = new DataGridColumn();
col.label = "New";
col.dataField = "new";
var columnData = [];
columnData.push(col);
ListTable.columns = columnData;
```
