Get ItemClass Attributes on Sales Order dialog box

Hi!

I’m trying to get the Attributes per ItemClassId to place them on a grid in the look up dialog box (Sales Order screen)

Like this:

I’m using the CSAttributeGroupList method:

public PXFilter<SOSiteStatusFilter> ItemSearchClass;
{
[PXViewName("Attributes")]

CSAttributeGroupList<INItemClass, SOSiteStatusFilter> Attributes;
public PXFilter<SOSiteStatusFilter> ItemSearchClass;

[PXViewName("Attributes")]

CSAttributeGroupList<INItemClass, SOSiteStatusFilter> Attributes;
}

However, It doesn’t bring any results.
