Is this an old page that just stopped working? Can you post a screenshot of the properties for the File Component? Does the ‘click and drag’ still work if you drag a file from your desktop?
This is a bug present in Brooklyn and Brooklyn Update. Thanks for sharing your workaround, Roman. We’ll let you guys know when a future release fixes this issue.
This issue may have been related to a bug that has now been resolved in the Brooklyn (10.0.4) Maintenance Release and the Brooklyn (9.5.11) Maintenance Release which are now available from the Skuid Releases page.
As a reminder, Salesforce does NOT allow reverting back to prior versions of managed packages. Skuid always recommends installing new versions in a non-business critical sandbox environment to test all mission critical functionality before installing into a production environment. We also recommend that you update out of date themes when you upgrade.
