Issue with Multiselector filter

I am using “multiselector” to apply filter on “Datatable” column, but facing the issue when I entered only comma (’,’) into the cell and when I apply filter on the column by selecting the comma from “multiselector” , at this moment filter is not working, instead of just showing the row containing the comma, it hide the row contains comma. I have also used escape character. kindly help me resolved this issue

By default the comma is used as value separator, you can reconfigure it though

{ id:"year", width:250, header:{ content:"multiSelectFilter", separator:";" }}
