I have JsonStore object and I need to find record with exact match for specific field. I tried 2 things:
1) when building JSON output on server side I added "id" param like that:
{"grid":[{"id":"1","m_regnum":"1610002346"}]}
then on browser side I call store.getById("1") but get undefined as return
2) I try calling store.find("id","1") and it does return correct index but... its partialmatch. In other words if I have another record with "id":13, it also will be found.

Is there way to either do complete match for the field or what do I make wrong in my #1 approach?

Thank you.
