[LON-CAPA-users] changing part name

[lon-capa-users@mail.lon-capa.org]

David,

You want to get a second opinion on this, but I'm afraid you probably 
don't want republish this.

The information as to student responses is stored in a large assessment 
file for each student. The information is stored as a hash - with 
key:value pairs. The key includes enough information to uniquely describe 
the information (which problem, which part, etc...). I think it is using 
this label that you chose to create part of this name (was this label the 
"id" for the part?) If you change the "id" of a part, it will not see that 
the student has any information regarding their submissions. In short, 
it'll look like the student never did the problem.

Sorry! I have no idea what the list of 'forbidden characters' is.

Later,
Mark
