Re: Example using Lists in Python?

[Joshua Kramer]

or specify InstitutionRecord as
{
      1: string REC_ID;
      2: i32 NumROFields;
      3: msgInstitution Institution;
      4: msgCSA CSA;
      5: list<msgROField> ROFields;
}
  

Thanks, Micheal.  The problem I'm running into, is this.  Assuming I 
have the above noted structure... the ROFields list is not set to any 
object type after I first instantiate the InstitutionRecord.  For the 
1-cardinality sub-structures (msgInstitution), I I just set the field to 
an instance of the sub-structure, eg

tObj.Institution = msgInstitution()

However, if I do this:

tObj = InstitutionRecord()
tObj.ROFields.append(msgROField())
tObj.ROFields[0].Name = 'Value 1'
tObj.ROFields[0].Value = 3.14

...Python says that the NoneType does not have an append method on the 
second line.

Any ideas?  This is Python 2.4.

Thanks!
