Log:
Change 20080118-lou-J by [EMAIL PROTECTED] on 2008-01-18 08:43:18 AST
in /Users/lou/src/svn/openlaszlo/trunk
for http://svn.openlaszlo.org/openlaszlo/trunk
Summary: fix live example order in the databinding chapter of the dguide
Bugs Fixed: LPP-3936
Technical Reviewer: (pending)
QA Reviewer: (pending)
Doc Reviewer: (pending)
Details: At some point, an example was inserted in this chapter, which threw
off the order of all following examples. Fix the order of the examples so
they appear in the proper sections.
One example file contained the wrong example; revert to the 3.4 version.
Tests: check that the examples match the 3.4 doc
