#34 plurality wrong for nested choice model groups

[Peter A. Bigot]

In the following schema (abstracted from wfs:FeatureTypeType), PyXB 0.5.1 incorrectly determines that "a" can appear multiple times.

<xs:complexType name="ftt">

<xs:sequence>

<xs:element name="a"/>
<xs:choice>

<xs:element name="b"/>
<xs:element name="c"/>

</xs:choice>

</xs:sequence>

</xs:complexType><

[Peter A. Bigot]

In the definition of _ _ fromModelGroup around line 940 of xmlschema/structures.py, change the branch for ModelGroup.C_CHOICE to read:

union_map = { }
for pd in pdll:

for pdm in pd:

union_map = self._MapUnion(union_map, pdm)

self.append(union_map)

i.e. create one union map over all possible documents rather than one for each set of documents.

• status changed from new to closed
• resolution set to fixed

Previous suggestion works for the specific case, but still isn't right. Full solution is more complex and will be in 0.5.2.
