Hi niksonawane
Please make sure that you are using different Plugin, Dialog, feature names
Apart, from that, you should be using different integer index at Line 46 -
tbGenerator.addElement(GROUP, plg.Plugin.SORT_FORMAT,
this
.pickerUI, 10);
and
tbGenerator.addElement(GROUP, plg.Plugin.SORT_FORMAT,
this
.pickerUI, 11);
