GetStrVal and Methods

[hcars]

GetStrVal is not working on TTables, returned by a method, when they are outside that method. Other methods to access numeric TTable entries are working. I have added a toy example of this issue below:

Python script to demonstrate problem

import snap

def my_reader_method(file_name):
    schema = snap.Schema()
    context = snap.TTableContext()

    schema.Add(snap.TStrTAttrPr("Src", snap.atInt))
    schema.Add(snap.TStrTAttrPr("Dst", snap.atInt))
    schema.Add(snap.TStrTAttrPr("weight_1", snap.atStr))
    delimiter = " "


    ttable = snap.TTable.LoadSS(schema, file_name, context, delimiter, snap.TBool(False))
    # This will work fine
    print(ttable.GetStrVal("weight_1", 0))
    ttable_iter = ttable.BegRI()
    print(ttable_iter.GetStrAttr("weight_1"))
    return ttable



ttable = my_reader_method("tests/systemtests/test_23/graph_23.edges")
try:
   # This will error
   print(ttable.GetStrVal("weight_1", 0))
except:
   ttable_iter = ttable.BegRI()
   # This will error
   print(ttable_iter.GetStrAttr("weight_1"))

Invocation

Invoke the above Python script with SNAP 6.0.0 and Python 3.8.5, and you should see the expected output print from inside the method and observe two errors outside the method.
