how to clear store.modified data after save the data!

[pclovec]

now i uses

1. var modified = store.modified;
2. updateData(modified);

to save data. but after first operation . such as second time save data ,i got duplicate data. it also send me all before change data.

i try to use store.modified=[] after updateData function seems doesn't work .

so how to clear or remove all modified data from store.
