Indexes declared in Archetypes schemata need to be moved to GenericSetup

This applies if you have moved from using 'install_types()' in 'Extensions/Install.py', to installing new content types/FTIs with GenericSetup using a 'types.xml' import step. For each field that specifies an 'index', like this example from "PoiIssue.py r40594":http://dev.plone.org/collective/browser/Poi/trunk/content/PoiIssue.py?rev=40594#L77 :: StringField( name='issueType', index="FieldIndex:schema", widget=SelectionWidget( label="Issue type", description="Select the type of issue.", label_msgid='Poi_label_issueType', description_msgid='Poi_help_issueType', i18n_domain='Poi', ), enforceVocabulary=True, vocabulary='getIssueTypesVocab', required=True ), …you need to move the creation to catalog.xml with GenericSetup. If there is 'index="FieldIndex"', that means you need a new index, of type FieldIndex, with the name being the name of the accessor method:: If there is also ':schema' or ':metadata', e.g. 'index="FieldIndex:schema"', you also need a metadata column:: This is necessary because the schema does not really exist at install time, so there is no way GenericSetup can inspect it and configure new indexes. This was a bad design from the start, as portal-wide indexes do not belong in type-specific schemata anyway.
