Subject [jira] Commented: (MYFACES-1358) PortletExternalContextImpl should massage RenderResponse.getNamespace() into acceptable ID
Date Wed, 04 Oct 2006 16:37:21 GMT
    [ ] 
Scott O'Bryan commented on MYFACES-1358:

You are incorrect.  The API specification for getNamespace reads:

"The value returned by this method should be prefixed or appended to elements, such as JavaScript
variables or function names, to ensure they are unique in the context of the portal page."

According to the W3C and ECMA specifications for javascript variables, function names, and
element id's, characters like the # are not valid characters for this purpose.  I'm of the
opinion that MyFaces should not have to fix a deficiency in the GridSphere framework.

> Hi,

this error:
> java.lang.IllegalArgumentException: Subsequent characters of component identifier must
be a letter, a digit, an underscore ('_'), or a dash ('-')! But component identifier contains

> It appears that PortletExternalContextImpl is using the RenderResponse.getNamespace()
method which in our case will return a string containing a #.

this is a bug in the PortletExternalContextImpl class-- probably in the

method can deal with.
