---------------------------------------
Summary: Component added using vdl.createComponent(...) is removed
when javax.faces.FACELETS_REFRESH_PERIOD is not -1
Key: MYFACES-3890
URL: https://issues.apache.org/jira/browse/MYFACES-3890
Project: MyFaces Core
Issue Type: Bug
Components: JSR-344
Affects Versions: 2.2.3
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Priority: Minor
On the way of implement MYFACES-3733 "Implement vdl.createComponent(...)", it
was noticed that when javax.faces.FACELETS_REFRESH_PERIOD config param is
different from -1, the programmatically added component dissapear after a
postback.
The problem happens because the code in vdl.createComponent(...) does an
"inline compilation" of a facelet instance of the component, but the original
algorithm does not consider that case. Instead, all facelets are stored in a
structure and the refresh period is used to decide when a facelet instance
needs to be reloaded.
The inline compilation makes a new facelet instance to be created every time
the component needs to be created or refreshed. The algorithm done in this part
is ok, the only thing that needs to be done is disable the refresh on the
sections that are compiled inline.
Unfortunately things are not so simple, because for example in a composite
component there are two facelets involved: one that makes the inline
compilation and the other that renders the component and is reused over and
over again. So, we need to review the algorithm to be sure everything is ok.
