JSF initial state
-----------------
Key: MYFACES-1019
URL: http://issues.apache.org/jira/browse/MYFACES-1019
Project: MyFaces
Type: Improvement
Components: Implementation
Versions: 1.1.1
Environment: Linux, WindowXP, JDeveloper
Reporter: Guy Bashan
I am having this problem for a long time and lost any hope of getting a decent
answer in any forum:
It seems like JSF does not give any solution to initial state problem.
A simple example:
I want to show a simple table that is being updated according to several
filters.
The table should be shown with initial data according to filters selections.
The actions that I am doing are:
1) To show initially the table, on the backing bean constructor I am loading
the table data.
2) On any "valueChange" of every filter I want to load the new data of the
table also, so I load the data again.
This causes the data of the table to be loaded twice: once in the constructor
and second in the value change listener method.
This problem happens in many variations many times in JSF. Is there a way of
initializing data properly ?
For example, I would expect that in addition to the constructor there will be 2
additional methods:
1) init() - Will be called when screen first loads.
2) reinit() - Will be called when screen is reloaded.
Am I missing here something ? Or there is a solid agreed way of solving the
initial state term in JSF.
By the way, I have to initialize data dynamically and not using managed
properties.
