Here is another note, that will hopefully help some other poor developer
that runs into the same problem. I'm implementing Dojo drag and drop for
a project. I'm refactoring the code so that a table is created from an
Ajax call as opposed to a static data. When the table data is static and
my table container has a static dojoType of dojo.dnd.source, everything works
fine. However, as soon as you add dynamic data to the table, drop stops working.
A javascript error "T is undefined" is generated and that is that.
The problem is cause by the fact that the dojo dnd code does not check the
container for updates. Consequently, when it finds new data in there, breakage
occurs.
The solution is to create your table first. Then, add the dnd features to the
table programattically. For example:
dndTable = new dojo.dnd.Source(dojo.byId("idOfTargetContainer"));
Voila! Dnd functionality is added and nothing breaks. I still have a few
table manipulation features. So if I run across any other tips, I'll be sure to
share.
