Wrong sequence of substitutions in GadgetServer
-----------------------------------------------
Key: SHINDIG-466
URL: https://issues.apache.org/jira/browse/SHINDIG-466
Project: Shindig
Issue Type: Bug
Components: Gadget Rendering Server (Java)
Environment: any
Reporter: christof kaleschke
When the substitutions take place in the method
GadgetServer.createGadgetFromSpec() this is done in the sequence: MESSAGE,
BIDI, USERPREF, MODULE. This sequence leads to wrong substitutions in the
following (complicated) case:
If the default_value attribute of a <UserPref> element contains a __MSG value
and a <ModulePrefs> attribute or subelement references this <UserPref> element
via __UPit is substituted to the __MSG value and not to the element from the
message bundle.
Take the example: http://www.google.com/ig/modules/youtube_videos.xml. There
the UserPref channel_url_to_preload contains the default_value
__MSG_recently_featured_rss__. A Preload element references this UserPref via
__UP_channel_url_to_preload__ in its href attribute. After the substitutions in
GadgetServer.createGadgetFromSpec() the value in the href attribute is
__MSG_recently_featured_rss__ and not
"http://youtube.com/rss/global/recently_featured.rss"; from the message bundle.
I think the sequence of substitutions should be: USERPREF, MESSAGE, BIDI,
MODULE.
