[Zope] Keyword Index Question

[VanL]

Hello,

I have an object which is included in a ZCatalog that watches, among 
other things, the attributes 'keywords' (for a keyword index) and 
'fulltext' (for a text index).

In the obect definition, I have the following code:

def __init__(self, default_catalog='mycatalog'):
    self.default_catalog = str(default_catalog).strip()
    self.keywords = self.get_indexable('keyword') 
    self.fulltext = self.get_indexable('fulltext')

    def get_indexable(self, index_type):
        " Dynamically build indexable attributes "
        propdict = PropertyManager.propdict(self)
        if index_type == 'keyword':
            keylist = []
            for propname in propdict.keys():
                thisID, thisVal = propname, propdict[propname]
                thisType = PropertyManager.getPropertyType(self, thisID)
                if thisType == 'string':
                    keylist.append(propdict[thisID])
                elif thisType == 'boolean':
                    keylist.append(thisID)
            return keylist
           
        elif index_type == 'fulltext':
            alltext = ''
            for propname in propdict.keys():
                thisID, thisVal = propname, propdict[propname]
                thisType = PropertyManager.getPropertyType(self, thisID)
                if thisType == 'text': alltext = alltext + propdict[thisID]
            return alltext
           
        else: return None

I also reindex_object each time I change a property, as shown in the 
example product ZCatalogedObject.

However, I don't get what I expect.  First, even though my class 
inhereits from CatalogAware, new objects aren't always added to the 
zcatalog.
Second, when I look at the keywords actually indexed, I see this:
       keywords [{'id': 'title', 'mode': 'w', 'type': 'string'}]

Any idea what I am doing wrong?

Thanks,

VL
