I have faces page called myworklist.xhtml.
On this page I use a richfaces datatable to display available work objects.
When a user clicks on a hyperlink the specific work item is retrieved from the database.
I notice the following:
During the initial load the backing bean reads the database 3 times before the pages is rendered. The same data is therefore retrieved 3 times from the database.
When the user selects an item the database is again read 3 times before the work item is displayed.
On the workpage, a button allows the user to take ownership of the workitem. At this time a jbpm process is updated with the task being assigned to the user.
Because 3 trips are made during each call, the jbpm process is asked to assign the task to the user thrice. On call 2 the jbpm process will throw an error.
I have been unable to determine why my backing bean methods are called multiple times and wondered if any hand on the ranch can maybe shed some light on this.
