> Key: MYFACES-2371
> URL: https://issues.apache.org/jira/browse/MYFACES-2371
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 1.2.7
> Reporter: Asuka Langley
> Assignee: Leonardo Uribe
> Fix For: 1.2.8-SNAPSHOT
>
>
> The problem occurs when the user wants to access to a .jsp page that includes
> a <f:subview> tag.
> It seems to be a bug on UIComponentClassicTagBase.getViewComponentIds(). It
> was fixed on 2.0.x branch but not on 1.2.x in this way:
> before:
> private Map<String,Object> getViewComponentIds()
> {
> Map<String, Object> requestMap =
> _facesContext.getExternalContext().getRequestMap();
> Map<String, Object> viewComponentIds;
> if (_parent == null)
> {
> // top level _componentInstance
> viewComponentIds = new HashMap<String,Object>();
> requestMap.put(VIEW_IDS, viewComponentIds);
> }
> else
> {
> viewComponentIds = (Map<String, Object>) requestMap.get(VIEW_IDS);
> }
> return viewComponentIds;
> }
> After:
> private Map<String, Object> getViewComponentIds()
> {
> Map<String, Object> requestMap =
> _facesContext.getExternalContext().getRequestMap();
> Map<String, Object> viewComponentIds;
> if (_parent == null)
> {
> // top level _componentInstance
> viewComponentIds = new HashMap<String, Object>();
> requestMap.put(VIEW_IDS, viewComponentIds);
> }
> else
> {
> viewComponentIds = (Map<String, Object>)requestMap.get(VIEW_IDS);
>
> // Check if null, this can happen if someone programatically
> tries to do an include of a
> // JSP fragment. This code will prevent NullPointerException from
> happening in such cases.
> if (viewComponentIds == null)
> {
> viewComponentIds = new HashMap<String, Object>();
> requestMap.put(VIEW_IDS, viewComponentIds);
> }
> }
> return viewComponentIds;
> }
