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).
