Hello,
I recently make an update of Bryntum and I notice that the mulsitselect filter don't show multiple values anymore. You can reproduce the problem here https://www.bryntum.com/examples/grid/filterbar/ and add this values to the filter :
filter : { property : 'city', value : ['Paris', 'Dubai'] }
'Paris' and 'Dubai' is not shown in the filter.
Regards,
Artbil
