Notes

  • Document viewing behavior differs depending on the document type and browser. Some browsers may render documents inline, while other browsers or file types may be downloaded. Browser plug-ins or extensions may impact this behavior. Consider the browsers that your users will be using to access your application.
    • Example: PDF documents are displayed inline in Chrome, Firefox, Safari, and Edge, but are downloaded by default in Internet Explorer 11.
  • On Appian for Mobile Devices, the document viewer component appears as a document download link. The value provided in altText is used for the link label.
  • Document not available will be displayed if the document is invalid, has been deleted, or the user does not have access to view it.
  • For security purposes, documents are loaded using the static content URL. Missing system configuration will be displayed if this domain is not configured on your Appian instance. Refer to Post-Install Configurations for more details on this configuration.
  • This component displays documents stored in Appian. To display documents from another system use the Web Content Field.
  • This component is not intended for displaying images or videos. To display an image from a document in Appian use a Document Image. To display a video use a Video Field.

Examples

Copy and paste an example into the INTERFACE DEFINITION in EXPRESSION MODE to see it displayed. Replace the document field value with a valid document in your environment.
