Hi everybody. I describe my emf model with some classes then extends others classes. For example:

@gmf.diagram(foo="bar")
class Schema {
val SchemaElement[*] contents;
}

abstract class SchemaElement {
attr String name;
}

class Table extends SchemaElement {
attr Boolean isGeographic;
}

@gmf.node(label="name", border.width="2")
class Dimension extends Table {
@gmf.compartment(layout="list", collapsible="false")
val Attribute[*] dim_attributes;
}

Im doing m2t with egl, and i need to access all dimensions from schema for iterate..but how do this? Schema contains SchemaElement[*] contents;

[%for (i in Sequence{0..(schema.dimensions.size-1)}){%]

thanks for the aswers Smile

How about using a select call and an isKindOf check?

[%for (d in schema.contents.select(se | se.isKindOf (Dimension))) {%]

Best regards,

Steffen
