findChild
A lighter-weight version of UIComponent's findChild.- Parameters:
parent
- parent to start searching fromid

if the given faces context is notFacesContext.isReleased()
, and its current phase ID is notPhaseId.RENDER_RESPONSE
. -
getLocale
According to Faces 1.2 tag specs, this helper method will use the TagAttribute passed in determining the Locale intended.- Parameters:
ctx
- FaceletContext to evaluate fromattr
- TagAttribute representing a Locale- Returns:
- Locale found
- Throws:
TagAttributeException
- if the Locale cannot be determined
-
getViewRoot
Tries to walk up the parent to find the UIViewRoot, if not found, then go to FaceletContext's FacesContext for the view root.- Parameters:
ctx
- FaceletContextparent
- UIComponent to search from- Returns:
- UIViewRoot instance for this evaluation
-
markForDeletion
Marks all direct children and Facets with an attribute for deletion.- Parameters:
c
- UIComponent to mark- See Also:
-
encodeRecursive
public static void encodeRecursive(FacesContext context, UIComponent viewToRender) throws IOException, FacesException - Throws:
IOException
FacesException

-
addComponent
Add the child component to the parent. If the parent is a facet, check to see whether the facet is already defined. If it is, wrap the existing component in a panel group, if it's not already, then add the child to the panel group. If the facet does not yet exist, make the child the facet.
