The problem occurs when index name in colModel contains "." (dot) .

Changing index:'p.name' to index:'pname' solved issue.

When I call clearToolbar(),  the grid content is refreshed, text fields in  filterToolbar are cleared except column with formater stype: 'slelct'

Select type filter persist untouched - contains the previous value (but filter value is not  sent to the URL).

I think this bug was introduced in jqGrid 4.x.x.

Is my explanation clear or do I have to prepare some example ?

Best regards
