attribute not transient must have datatype serializable [message #526069]

Hi All,

I am creating an ECore model. I created an EClass and inside it I want to create a data member that is a list. So I created an EAttribute of type EEList.

However when I try to create the genmodel file I get an error saying

the attribute "XYZ.Attribute_name" is not transient o it must have a data type that is serializable.

It also gives a warning saying

The generic type associated with the 'EEList' classifier should have 1 type atrgument(s) to match the number of type parameter(s) of the classifier.

Can anyone tell me what I'm doing wrong? I could not figure out how to set the 'E' in EEList <E>.

Thanks.
Rajesh

It sounds far more likely that you should be defining an EAttribute with
upper bound -1 (unbounded) and using the EType to specify the item
type. That's the best way to define serialization support. Otherwise
you'll need to defined your own EDataType as well as specify how to
serialize it in the generated XyzFactoryImpl.
