MFXComboBox is not working when tried to select item from dropdown items by touch

[mksbabu]

Hi Team,
I am trying to use MFXComboBox for javafx application
ComboBox control is not working by touch if I want to select any item from dropdown values and application is closed automatically when I put my finger on required item, but It's working if I select any item by mouse click. could you please anyone help me on this issue with touch screen?

Thanks in advance!!
