Sorry, got interrupted... ;q
Thanks, Francis, that works (2013 SP1 )!
What still gives me troubles is setting the MaterialID attribute (exists
on every polymesh by default), which is what I actually need.
I cannot write to it. Reading works, though. Could you guys please have
a look?
This works:
<JScript>
NewScene("", "false");
var oObj = CreatePrim("grid", "MeshSurface", "", "");
SetValue("grid.polymsh.geom.subdivu", 2, null);
SetValue("grid.polymsh.geom.subdivv", 2, null);
var oICEAttr = oObj.ActivePrimitive.AddICEAttribute("MyAttr",
siICENodeDataLong, siICENodeStructureSingle, siICENodeContextComponent2D );
oICEAttr.DataArray = [0,1,2,3];
var oProp = oObj.AddProperty("AttributeDisplay");
SetValue(oObj.Name + ".AttributeDisplay.attrname", "MyAttr", null);
</JScript>
Whereas this throws a warning:
<JScript>
NewScene("", "false");
var oObj = CreatePrim("grid", "MeshSurface", "", "");
SetValue("grid.polymsh.geom.subdivu", 2, null);
SetValue("grid.polymsh.geom.subdivv", 2, null);
var oICEAttr = oObj.ActivePrimitive.GetICEAttributeFromName("MaterialID");
oICEAttr.DataArray = [0,1,2,3]; // WARNING : 3403 - The data is not set
on this ICEAttribute: MaterialID
var oProp = oObj.AddProperty("AttributeDisplay");
SetValue(oObj.Name + ".AttributeDisplay.attrname", "MyLong", null);
</JScript>
The attribute "MyAttr" has exactly the same "format" as MaterialID, so
what's the difference?
Using a GridData object does not help.
<JScript>
NewScene("", "false");
var oObj = CreatePrim("grid", "MeshSurface", "", "");
SetValue("grid.polymsh.geom.subdivu", 2, null);
SetValue("grid.polymsh.geom.subdivv", 2, null);
var oICEAttr = oObj.ActivePrimitive.GetICEAttributeFromName("MaterialID");
var oGridData = XSIFactory.CreateGridData();
oGridData.RowCount = 1;
oGridData.ColumnCount = 4;
oGridData.SetRowValues(0, [0,1,2,3]);
oICEAttr.DataArray = oGridData.Data;
var oProp = oObj.AddProperty("AttributeDisplay");
SetValue(oObj.Name + ".AttributeDisplay.attrname", "MyLong", null);
</JScript>
Am I missing something, or is this a bug?
Thanks!

The size of the array will depend on the siICENodeContextType associated with
the ICEAttribute and the object containing this ICE Attribute.

attr.DataArray = [
