Extensible Storage using arrays

Hi All

I have managed to store an array of elementIDs using Extensible Storage, but am having trouble reading the information back.

To save the data I have used:

Dim entity As New Entity(schema)

' get the field from the schema

Dim ExcludedTitleblocks As Field = schema.GetField("ExcludedTitleblocks")

' set the value for this entity

entity.Set(Of IList(Of ElementId))(ExcludedTitleblocks, tbList)

' store the entity in the element

doc.ProjectInformation.SetEntity(entity)

I am trying to read the data back using this (but I get an error with the last line):

Dim ExcludedTitleblocks As Field = s.GetField("ExcludedTitleblocks")

Dim retrievedEntity As Entity = doc.ProjectInformation.GetEntity(s)

Dim retrievedData As IList(Of ElementId) = retrievedEntity.Get(Of IList(Of ElementId))(ExcludedTitleblocks)

The error is "The field belongs to a different Schema from this entity, or this Entity is invalid."

(I had working code when I was only storing a simple elementid field)

Please can anyone help with the correct syntax?

Thanks

Wierdly this seems to be working now, but the code hasn't changed.

I think that the only thing that I did was close VS and start again. Maybe I changed a field name and that persisted until I restarted VS.

Confused....
