I have multiple grids inside tabs (YUI's TabView), and they work almost perfectly. However, when switching between the tabs, the widths of the columns tend to overwrite each other. It looks like this is caused by both grids using the same CSS classes. My current hackish solution is to have an event handler that fires when the active tab changes to call column_model.fireEvent('widthchange'), which resets the CSS classes to have the currently visible grid's widths. Is there a better fix for this and/or is this an issue that's resolved in version 1.0?
