Facing issue when filter the data from extjs store

[Arun Jindal]

I want to filter the data from extjs store without case senstivity. So for this i use below code.
store.filter([
{
property: colName,
value: compareVal,
id: colId,
caseSensitive: false
}]);
Above code is working fine but if i passed one more parameter i.e. operator

store.filter([
{
property: colName,
value: compareVal,
id: colId,
caseSensitive: false,
operator: operatorCheck
}]);



Now above code is not working. Please help me out of this.

Example:
Suppose my store contain following values
abc, ABC, cde, CDE, efg
I want all the records except abc // store not contains abc (!= abc)

o/p should be: cde, CDE,efg

Moved from Community Discussion. Which specific version of Ext JS is this? Does the second version work if you temporarily remove the caseSensitive config? What is the value of operatorCheck?
