Hello,
I think there's a little bug on shale view 1.0.4.
Shale View : Bug on render response phase when removing view from request
map.
Error in org.apache.shale.view.faces.ViewPhaseListener, method
afterRenderResponse, lien 233 :
iterator obtained from map, code calling map.remove, and afterward using
iterator which generated ConcurrentModificationException.
Just change this order :
- remove FacesConstants.VIEWS_INITIALIZED from map.
- obtain iterator.
- use iterator.
I've just changed this piece of code in order to have :
private void afterRenderResponse(PhaseEvent event) {
/*AFTER CHANGE*/
// Initialize local values we will need
Map map = event.getFacesContext
().getExternalContext().getRequestMap();
List list = new ArrayList();
// Remove our list of initialized views explicitly
map.remove(FacesConstants.VIEWS_INITIALIZED);
Iterator entries = map.entrySet().iterator();
instead of :
/*BEFORE CHANGE
// Initialize local values we will need
Map map = event.getFacesContext
().getExternalContext().getRequestMap();
List list = new ArrayList();
Iterator entries = map.entrySet().iterator();
// Remove our list of initialized views explicitly
map.remove(FacesConstants.VIEWS_INITIALIZED);
And it's ok (or it seems).
Adrian,
Thanks very much for the thorough analysis ... it looks like you are on
target (although it likely depends on your VM's implementation of the
iterator methods so the problem may or may not manifest itself everywhere).
Could you do me a favor and file a bug in our issue tracking system[1] for
this? That way, the eventual fix will automatically be included in the
release notes for the next version.
