Issue
- When you submit a file in the Documents and Media portlet that has the same title as a different file, an error is produced that prevents you from submitting it. When this happens, the file is lost from the form field because the page is reloaded. For security reasons, we are unable to programmatically repopulate the input of type file when the submission fails. This is a technical limitation, present in browsers for security reasons.
Environment
- Liferay DXP 7.0
- Liferay DXP 7.1
- Liferay DXP 7.2
Resolution
-
One of the drop down error messages prompts the user to re-select the file that they would like to upload, in addition to changing the name of the title. Once this is done, the file can be published, and the preview will be generated.
- If the user submits again without re-selecting the file, Liferay will generate a 0 KB file that has the name of document, as a placeholder.
