isPostBack() claims falsely TRUE in the View bean being forwarded to
--------------------------------------------------------------------
Key: SHALE-455
URL: https://issues.apache.org/struts/browse/SHALE-455
Project: Shale
Issue Type: Bug
Components: View
Affects Versions: 1.0.4
Environment: not relevant
Reporter: Stan Zapryanov
In the following scenario:
Postback processed by page A, which then navigates to page B:
Backing bean for page A is instantiated during Restore View phase, which
notices that there is previous state to restore.
The setPostback(true) and init() methods on your backing bean for page A are
called.
....
IT also seams that the setPostack(true) is called on page B (inappropriately)
since the request attribute remains in the map and bean B is created by the
following code in the constructor:
In ViewViewHandler :
private void setupViewController(FacesContext context, UIViewRoot view,
String viewId, boolean postBack) {
// Is there actually a view for us to procses?
if (view == null) {
return;
}
// Cache the postback flag so that it can be used inside
// the AbstractViewcontroller implementation
if (postBack) {
context.getExternalContext().getRequestMap().
put(FacesConstants.VIEW_POSTBACK, Boolean.TRUE);
}
//FIX STARTS HERE
else {
context.getExternalContext().getRequestMap().
remove(FacesConstants.VIEW_POSTBACK);
}
//FIX ENDS HERE
