Hello,

I tried to export some meshes with a ColorLegend using the WebGL module but without succeeding. A sample code :

CS = colorscale.ColorScale(palet='RAINBOW', minval=0., maxval=max_value)
CLA = decors.ColorLegend(CS, n_colors, 60, 50, 40, 600, lefttext=True)
decorate(CLA)

W = WebGL(name='myname', cleanup=True)
W.addScene()
W.addActor(CLA)
W.exportScene()
W.export()

With this code, the html file is just blank (with the pyformex logo), no mesh or controller displayed. If I remove the instruction W.addActor(CLA), all meshes are correctly displayed, but the ColorLegend does not appear, although it seems that a .pgf.gz corresponding to the actor is written. The controller doesn't seem to have the ColorLegend actor listed either.

I'm not quite sure if the sequence of instructions is correct or why the html is blank when adding the ColorLegend to the scene. Or maybe the decorators are not meant to be exported ?

I'm using pyFormex 1.0.2-a6.
