[Opensg-users] OpenSG2: Compiling generated attachment fails...

[Johannes B. <jb...@da...>]

Hello,

 

I have generated a simple attachment class with the following field
container description:

 

<?xml version="1.0"?>

 

<FieldContainer

                name="HighlightMaterialAttachment"

                parent="Attachment"

                library="ContribDataSolid"

                pointerfieldtypes="both"

                structure="concrete"

                systemcomponent="true"

                parentsystemcomponent="true"

        decoratable="false"

        childFields="none"

        parentFields="none"

 

> 

DataSolid attachment that stores the actual non highlight material on
highlighting.

                <Field

                               name="material"

                               type="ChunkMaterialPtr"

                               cardinality="single"

                               visibility="external"

                               access="public"

                >

                The material to be tracked.

                </Field>

</FieldContainer>

 

Unfortunately something is wrong here because the generated classes do
not compile. I got the following error message:

Can anyone give me some help on how to write a correct field container
description file for an attachment just carrying a single
ChunkMaterialUnrecPtr  ?

 

Best,
