File Picker - How to retrieve the uploaded file

[relsecu]

I'm trying to use the "File Picker" input component in a Camunda form to upload a file.

The resulting variable contains a string that starts with "file::".

Could you please tell me how to retrieve the actual file in order to:

• send it to an external destination (e.g., a REST API),
• display it using the "Document Viewer" component?

I am using 2.0.0 version

Thank you for your help!

Thank you for your question!
We’ve recently added support for the File Picker component, and the feature will be available soon — at least in the upcoming snapshot version. This likely explains the difficulty you experienced when trying to download the file.

In addition, we're planning to introduce support for document preview component from bpmn-io forms library, which will enable seamless file viewing directly within the form.

We appreciate your patience and will keep you updated as these enhancements are released.

Hi @dmitrymalk ,
Do you have any updates regarding the release of this feature? 🙂
Thanks in advance!

Hi @relsecu , thanks for checking in! 😊
The File Picker component is now supported in both the 2.1.0-SNAPSHOT version and the 2.1.0-alpha release (https://github.com/cibseven/cibseven/releases) — so you should be able to use it right away.
As for the document preview feature from the bpmn-io forms library: development is complete, but it hasn’t been included in the snapshot release just yet. It’ll be available soon, and we’ll make sure to keep you posted once it’s live.

Hi @relsecu , just a quick update
The preview components are now available with the 2.1.0-SNAPSHOT build. This means you can already try them out in your project alongside the File Picker.

To connect the File Picker with Document Preview component, you can simply set the File Picker’s key as the value for the Document Preview’s documentReference field. This way, the two components will be linked and files selected via the picker will automatically be available for preview
