An ace:dataTable has a panelExpansion for every row. This is controlled via the expansionToggler component. Expanding the rows works fine in a un-filtered data set. Upon filtering a column the expansion no longer works correctly. Clicking the first rows expansion icon does not show the expansion. Clicking the second rows icon will then not only display the second rows expansion it will also show the first rows. Trying to close the expansion results in odd behavior also.
