[Bug]: Execute button is greyed out after uploading a data source file

[MarkTro]

Expected behavior

After uploading a file within the field File on the tab Data source the button Start on the tab Execution is not greyed out, that the import is executable.

Actual behavior

After uploading a file the button is greyed out.

In addition this is confusing: If you haven't uploaded a file yet, the button is normal and clickable. Usually I would expect that the button is greyed out, because no file exists which can be imported.

Steps to reproduce

• Pimcore is in Prod-Mode (APP_ENV=prod).
• The config is stored in the symfony-config.
• The folder /var/tmp/datahub/dataimporter/upload/store-import is empty (no file uploaded before).
• In the backend go to the Data hub config and click on your Importer-Config.
• Switch to the tab Execute and see the Start button is active.
• Switch to the tab Source and upload a file.
• Switch to the tab Execute. The Start button is deactivated, now.
• In addition; The config is marked as changed by an asterisk.

Additional info:

• If you close your configuration (Confim closing with yes) and open it again the import is startable.

It seems that upload is handled as a config change.

To solve this problem ExtJS modification are necessary. A field I'm not familiar with.
