Auto allocation of tab-indices has reached native browser ceiling - tab-order cannot

Hi ,

Using dynamic form trying to create 5 items of File upload. Dynamic form has combination of Text item and FileUploadItems. As mentioned I am getting view when on draw. But getting warning in the console as "Auto allocation of tab-indices has reached native browser ceiling - tab-order cannot " ,
<warnings>

</warnings>

":WARN:DynamicForm:isc_CustomDynamicForm_6:colWidths Array shorter than numCols, remaining columns get '*' size"


It seems like giving Numcol size or width of some items giving warning.

Could you please suggest to avoid warnings.
