Bug 128359 The logic is not correctly when a filter is added to the table on the layout
Description: The logic is not correctly when a filter is added to the table on the layout Steps to reproduce: Let me give an example. 1. Creat a report, new a datasource and a dataset 2. We consume that the dataset has 10 records(DataResult_A) . We set a filter(Filter_A) in the dataset, and then the 6 records of the dataset(DataResult_B) are gained. 3. Drag the dataset to the layout, and set another filter(Filter_B) on the table. Actual result: The result of Filter_B is based on DataResult_A. Expect result: The result of Filter_B should be based on DataResult_B.
