[jira] Created: (MYFACES-2239) Backing bean method called too often (recursively?)

Backing bean method called too often (recursively?)
---------------------------------------------------

                 Key: MYFACES-2239
                 URL: https://issues.apache.org/jira/browse/MYFACES-2239
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 1.2.6, 1.2.5, 1.2.4, 1.2.3
         Environment: linux & windows, but doesn't matter.
(Found in an Appfuse project)
            Reporter: Marcel Rokers


After the save button is pressed a method in the backing bean is called (getUser_bos()) to fill the selectManyCheckbox, first time only one time. But every time you press save and have selected something it becomes more.

This is to timeconsuming for my project, so I had to go back to 1.2.2, but in that version I have another bug that is irritating my project (and is solved in 1.2.3).

Has anybody a sollution or is this reported before (I didn't find it).
