jQuery Grid Plugin - jqGrid

I have 2 same grids on my page,

data are from the same table but by different criteria (so no ids overlap). Grids are shown on differen jquery ui tabs (failed records, success records).

I have found that filter toolbar inputs have the same ids generated. It haven't created problems until I have added support of datepicker and operation selector to grid. Anyway having multiple elements with single id could cause problems for any javascript access logic.

P.S. Have found similar bug "Multiple jQgrids WITH filtertoolbar in jqueryUI Tabs causes JavaScript Errors".

PPS. Previous bug is related but have other roots. Column model  when calling buildRuleMenu incorrecly bound to second grid when clicking actually is on first
