Hi all,

Here is the index_html of a product with the index_html embeded in the module source-

    def index_html(self,width=100, height=200,RESPONSE=None,REQUEST=None):
        "This is the index_html method"
        im=PIL.Image.new('RGB', (width,height))
        draw = PIL.ImageDraw.Draw(im)
        draw.rectangle([0,0,0,0], fill =(0,0,0))
        RESPONSE.setHeader("Content-type", "image/gif")
        outFile = cStringIO.StringIO()
        im.save(outFile, 'gif')
        RESPONSE.write(outFile.getvalue())
        return ''
    

If I call an instance of the product from a dtml method with <dtml-var bar> I get my picture.

If I call an instance of the product from a dtml method with <dtml-var bar(100,100)">, I get-

Error Type: AttributeError
Error Value: __call__
