How to turn on History Management, and what it does to applications…
An example workspace is loaded, and WebApp.src is opened in the DataFlex Studio.
Inside the WebApp object is a property called peApplicationStateMode. This can be set to one of 3 values:
asmOff means History management is not being used
asmHistoryOnly means History management is being used, but no unique URLs are generated
asmHistoryAndUrls gives full functionality of History Management with deep linking
In the demonstration, it is initially set to ‘asmOff,’ and the application is compiled and run. This simple application only has three views: a dashboard, selection list and a details view. When clicking through the application the URL never changes – it remains static.
Next, it is set to ‘asmHistoryAndUrls,’ and it is run again. Clicking through the application now shows that the URL changes depending on what part of the application is accessed.
Note that when an application is created in DataFlex 19.1, this object is set to asmHistoryAndUrls by default.
