<p>To check wether a type supports ID properties, just try to use

<div>Hi. I need assign custom properties to mesh vertices, edges
and faces. It doesn't throw any errors on creation of the
custom props, but after they've been created, they don't
behave as one would expect. They are read-only tuples rather
than bpy.props.IntProperty() for example.<br>
<br>
</div>
For comparison, here's the normal behavior of a custom property<br>
<div>
<div><img src="cid:part1.AB8D399E.49D75E36@wanadoo.fr" height="60" width="387"><br>
<br>
</div>
<div>Here's what I get on certain bpy.types<br>
<img src="cid:part2.0396229D.750917CC@wanadoo.fr" height="61" width="430"><br>
</div>
<div>An unusable tuple!<br>
<br>
</div>
<div>And if I try to assign a value, I get<br>
<img src="cid:part3.52291FA6.F9D2E730@wanadoo.fr" height="65" width="440"><br>
<br>
<br>
</div>
<div>Is there a reason for this? Is there a known workaround
or hack? I really do need to store custom props on vertices,
edges, faces and vertex groups.<br>
