Error progressing item through stages after recover webpage
An error occurred when resubmitting an action on a work object. The issue occurred after a slow-response warning on an Internet Explorer webpage.
The change to stage is the same as the current stage
Steps to Reproduce
- Slow down the network between the browser and the application server such as by using Fiddler's option to simulate slow network performance.
- Submit an action to progress the stage of a work item. Due to the simulated slow network, a notice from Internet Explorer stating that the page may not be responding will be displayed.
- Click Recover Webpage button. User is taken back to initial screen.
- Attempt to submit the action again, and observe the error message.
Recover Webpage option forces a meta-refresh of the page which re-submits the previous screen's information. As a result of this, Pega tries to change stage, but it finds that it is already in the stage that it is trying to change to. Hence, the error is occurs.
Do not use the Recover Webpage option in Internet Explorer to attempt to remedy a stalled page. The meta-refresh is not appropriate for a stateful web application.
