PDF link
(section Basic properties)
A relative path to a file placed in a folder in the environment, or an external link, however in that case it must meet the CORS policy requirements (the Access-Control-Allow-Origin header must be set appropriately).
By default, the property is set to empty.
Important: Entering an incorrect URL or not entering one at all causes an error and prevents the application from being filled in after attempting to display the PDF file.

This value can be entered directly as a static link or passed dynamically using a variable. 1. Path to a file available in the environment This involves providing a path to a static resource placed directly in the application server's directory structure.  2. External URL address This involves providing an absolute URL to the file. However, the external server must allow the browser to download the file from the application, in accordance with the CORS policy.  {% hint style="info" %} CORS is a security mechanism in web browsers. It blocks downloading resources (e.g. PDF files) from a domain other than the one where the form is located, unless the target server explicitly allows it by sending the appropriate HTTP header (`Access-Control-Allow-Origin`). {% endhint %} 3. Filling the component with a session variable value The PDF file address can be dynamically filled with a session variable value. In the field `PDF link` you can use a reference to a variable (e.g. `${pdfUrl}`), which will be filled with a value coming from a script or service.   {% hint style="info" %} When filling the component with a session variable, remember to add a listener for this variable. {% endhint %} {% hint style="info" %} Note that the session variable value cannot be empty — otherwise the application will not work properly after attempting to display the component. {% endhint %} {% hint style="info" %} Demo applications: demoPdfViewer {% endhint %} --- # Agent Instructions This documentation is published with GitBook.
