New Revision: 11775
Added:
trunk/Open-ILS/web/js/dojo/fieldmapper/AutoIDL.js
trunk/Open-ILS/web/js/dojo/fieldmapper/IDL.js
Log:
IDL.js -- Retrieves the fm_IDL.xml file and builds fieldmapper classes based
on its contents. This retrieval is syncronous, and times out after 10s. If
it times out, the older fmall.js method is used to build fieldmapper classes.
If you load only this packaged then you must call fieldmapper.IDL.load() after
the dojo.require() call.
AutoIDL.js -- A simple wrapper to IDL.js which calls fieldmapper.IDL.load() so
that the user doesn't have to.
