Comment 2 for bug 686116

Mainly for modularity reasons, you know that graph and attributes are separated in gephi. You may also know that you can write attribute values only if the column exists; and has therefore been created somehow.

The pushFrom method fails here because the columns haven't been created in the new workspace. Its a pity it doesn't take this classic issue in account and raise a proper exception.

Anyway, do that to duplicate the attribute model in the new workspace:

AttributeModel sourceAttributeModel = attributeController.getModel(currentWorkspace);
AttributeModel destAttributeModel = attributeController.getModel(newWorkspace);
destAttributeModel.mergeModel(sourceAttributeModel);
