[OpenLayers-Users] DrawFeature control not working properly

[Jatin Ambasana]

Hello Eric,

I also had another problem that came to notice some what late.....
The program that I had attached in last post (polygons.html) does work fine
but it shows a error occurred symbol on left hand side of browser's status
bar.
On checking the symbol I get to see following error:
Line: 379
Char: 9
Error: 'this.layer.renderer' is null or not an object

Although it is not giving any problem in working of the code but I am not
able to understand why it is giving such error.
I feel I should take its care now itself since I am going to extend the code
with some more functionalities.

But I don't know where to look for and I don't know anything about Renderer
and its working....
