Enabling asynchronous web content rendering
You enable asynchronous web content rendering by using the Edit Shared Settings or Configure mode.
Before you begin
To enable asynchronous web content rendering, a user needs sufficient access rights: At least either Manager role privileges on the page with the Web Content Viewer or Manager role privileges on the Web Content Viewer portlet itself.
About this task
To enable asynchronous web content rendering for a single portlet instance, use the following procedure.
Procedure
Optionally, you can also set a timeout for the loading icon for asynchronous web content rendering. If you enable this timeout, the portal marks web content as unavailable, if it takes too long to render. To enable the timeout, proceed as follows:
Results
The web content now renders asynchronously. Until the web content is available, a loading icon and corresponding text appears.
What to do next
- If a timeout occurs, the placeholder area of the Web Content Viewer removes the waiting icon and displays an error text instead.
- If the request fails on the server side inside the serveResource method, an HTTP error code is displayed in the placeholder area with a corresponding IBM® Web Content Manager error message.
- Issues in the web browser such as missing libraries or theme profiles are displayed in a similar way to indicate the problem.
