Exported CSV is empty when a filter is applied.

I know this is old, but it's still appearing for me. I fixed the issue by changing the exposed filter widget (Selection type) from Autocomplete to Dropdown. This fixed the issue and the correct data was exporting for me as CSV and JSON. I tested this issue / solution for both CSV and JSON.

We were able to reproduce this challenge using those steps

Steps:

1. Add an Autocomplete filter to your View.

2. Using the View above, using the Autocomplete filter, search for keywords which includes those two bracket symbols [ and ]. For example, search for this [Keyword]

3. Click on "Filter" button to display the result

4. Results are all displayed

5. Using views_data_export module, export to a CSV file

6. Open the CSV file you created above

7. The first line is included in the results. This is the header. But all the data is not included. In other words, the table header is included, but starting on line 2, all data is missing. This is the challenge. The needed end result is that all data is included in the CSV file. Not just the header.

8. Redo all the steps above, except, remove the two bracket symbols from the filter. Now all data is included in the CSV file. So somehow, the two bracket symbols are related to this challenge.

Using views_data_export 7.x-3.2 or more recent stable version

You can disable the access checks under the options Query Options in the view and that should allow you to download all results.
