I've run into an issue that I can't seem to find a work around for within the current GXT 3 code base. I have a grouping grid that has multiple columns including a date column. I've applied a format to the dates that appear within the cells by applying an abstract cell render but can't seem to figure out how to apply a format to the date when the grid is grouped by that column. To see what I'm talking about please look at the grouping grid example (http://www.sencha.com/examples/#Exam...nggrid). You will see the nicely formatted dates when the page initially loads (<code class="java string">"MM/dd/yyyy"</code><code class="java plain"></code>) but when the grid is grouped by date that formatting goes away and it's displaying the full date. Does anyone have any ideas on a work around to fix this?
