Hi everyone

i added custom field to the mail object , and i want use the added custom
filter to retrieve email messsage by soap ,but i can`t get right mail.
the filter is seems not work.

the following is to construct the filter:

Filter gwFilter = new Filter();
FilterEntry gwFE = new FilterEntry();

Custom cu = new Custom();
cu.setField("GWiseConst"); // "GWiseConst" is custom field, added by me.
cu.setValue("10"); // "10" is custom field value, added by me.



after that call getItemsRequest method by soap.
how to make this filter work well?
