 Q: Problem with displaying geometry in PROTOS


        I am working on a project where I have several PROTO's arranged in a
hierarchy; PROTO A contains a node for geometry which is implemented by
IS'n to a Group's children field.  PROTO B contains a field to hold a
node of PROTO A; PROTO C has a field for holding a node of PROTO B.
When I instantiate PROTO A, B, and C, nothing is displayed. When I use
PROTO A alone, all is well.  Any help?

Here is some example code:
        PROTO protoA [field     MFNode          visualDef       []] {
                Group {
                        children IS visualDef

        PROTO protoB [field     SFNode          protoAField     NULL
                        eventIn SFBool          flag] {

                DEF internShape Shape {
                        geometry IS protoAField

                Script {
                        field   SFNode  intern_field    USE internShape
                        eventIn SFBool  intern_Flag     IS flag

                        ....do stuff....

        PROTO protoC [field     MFNode          protoBField     []] {
                Group {
                        children IS protoBField

and then I instantiate it as follows:

        protoC {
                protoBField [
                        protoB {
                                protoAField protoA {
                                        visualDef [
                                                Shape {
                                                        geometry Box {}

Why does this not display the box ?

you put a Group node into the geometry field. The geometry field
expects one of the geometry nodes instead (Box, Sphere, Text, etc.)
