I stepped through the code and you are quite right that the first CampaignType object \
passed to BasicEntityConverter's getIdAsString method has null values in its fields.

If I modify the BasicEntityConverter code to not throw an exception, then I see that \
on the second and third calls to the getIdAsString method, the entity argument \
contains the CampaignType objects I would expect.

customerTypes.resultList is populated by a Seam Application Framework Entity-Query:

<framework:entity-query name="customerTypes" ejbql="select customerType from \
CustomerType customerType" />  | 

I've checked that my entity-query only returns two CustomerType objects which have \
non-null id values.

My si:selectItems tag is as follows:

<h:selectOneMenu value="#{customerHome.instance.customerType}" id="customerType">
  |   <si:selectItems value="#{customerTypes.resultList}" var="customerType" \
label="#{customerType.name}" noSelectionLabel="Please Select..." />  | \
</h:selectOneMenu>	

So now I'm more than a bit confused as to how a CustomerType with a null id value is \
being passed to BasicEntityConverter's getIdAsString method.

Does the object from the <h:selectOneMenu> value property get passed to the \
BasicEntityConverter??? The reason I ask is because I'm creating a new Customer and \
therefore #{customerHome.instance.customerType} would initially contain a new \
instance of CustomerType. If so, how do you work around this?

Any help would be very much appreciated as I'm starting to tear my hair out...

Cheers,

Lawrie
