summaryType configuration missing from column when GridSummary feature used

[RandyIntegra]

Im trying to add the Summary Feature to a grid panel, via ext designer. The feature itself is available, however, the "summaryType" config option seems to not exist. Further more, I cant seem to find anything about this option in the grid column docs:

http://docs.sencha.com/ext-js/4-0/#!/api/Ext.grid.column.Column

however, it is shown in the example for the summary feature:

http://docs.sencha.com/ext-js/4-0/#!/api/Ext.grid.feature.Summary

columns: [{
        dataIndex: 'student',
        text: 'Name',
        summaryType: 'count',
        summaryRenderer: function(value, summaryData, dataIndex) {
            return Ext.String.format('{0} student{1}', value, value !== 1 ? 's' : ''); 
        }

By following standards, I cannot directly modify the outputted UI file. So my question is, how can I make this work, without editing the ui file, and without promoting every column to a class?

Also, please add this option to the API docs, Im assuming this is missing from designer because it was forgotten in the API.

Thanks

It appears that a reply in this forum is a rare occurrence. Is there a better place to post this issue?

Randy -

Sorry for the late response. We are heavy under development of Designer 2.0 and missed this. You are correct in assuming that this was missed because of it not being in the docs. I will move this thread and create a bug report based off of it.

Unfortunately for this particular case I cannot think of a simple work around without hand editing the file.

Thank you, this is exactly what I needed to know.
