Save criteria of FilterBuilder?

[family.labrador@outlook.com]

Hi,

Is it possible to save the criteria created by filterbuilder? I have tried so far something like

JSONEncoder encoder = new JSONEncoder();
encoder.setDateFormat(JSONDateFormat.DATE_CONSTRUCTOR);
String criteriaValue = JSON.encode(advancedFilter.getCriteria(true).getJsObj(), encoder);
GWT.log("A:"+criteriaValue);

But it doesnt work. Is it possible to save the criteria? The idea is to store the crit in s database and the user can retrieve it later.

Thx
