I understand there is a File Viewer control in Content Management but given a scenario where there is an external documentum integration – is there a control that can be used as ‘File Viewer’ that can take the doc ID (for example) as an input and render the file contents in the interface.
There is not a currently existing feature to provide the File Viewer with a Document ID. You could programmatically determine the path to the file given the DocID and ECM server configuration, and provide the File View with a URL.
If you feel that this should be an included functionality out of the box, please submit an Enhancement request here as IBM now owns the SPARK UI Toolkit. (Currently included with BPM 8.5.7 CF201706 and higher)
If you have an urgent requirement for this functionality, please feel free to contact our Sales Team regarding an Engagement in developing a custom control or enhancing an existing one to fit your needs.
