[Glass] Indexing question

Hi Richard,

Let say i create the class FormFieldValue (name,value). name a string and
value a string/integer/date/time (a basic value)

Now FormInstance has collection of FormFieldValue. If two forms has the same
subset of names then they are the same type of form.

We have a back reference to the form which holds these fields, [xmlString]
holds a XML that represent the form.

The only way i see to create an index on values is to have a collection of
these FormFieldValue that represent all forms of this type and then create
the index over this collection.

collectionOfFormFieldValues createEqualityIndexOn: 'name'. "all forms of
type 1"
collectionOfFormFieldValues createEqualityIndexOn: 'form_code'. "all forms
of type 2"
and so on...

Is this your suggestion ?

Thanks very much...

Do you see any problem in holding an XML string representing the form inside
GemStone ?
or it will be better to write down the xmlString to disk ?
