Changeset 7108 for main/waeup.sirp/trunk

Timestamp:

14 Nov 2011, 10:01:17 (13 years ago)

Author:

Henrik Bettermann

Message:

Reorganize file upload. Each viewlet gets an upload and a delete button and writes its own log message. Thus there is one line per file deletion or file upload in the log file. The save action does no longer upload the files.

It works perfectly in the UI but I have still some problems with the browser test.

• browser.py (modified) (3 diffs)
• browser_templates/fileupload.pt (modified) (2 diffs)
• tests/test_browser.py (modified) (2 diffs)
• viewlets.py (modified) (7 diffs)
