I am trying to edit a model with a fleximage. I can create the model  
with out the image by adding:  
self.require\_image\_data = false

But once a user has added an image they can only upload new images not  
remove the image. When I try to set the model.data = nil  
I get the following error:  
Exception in edit\_module: /var/www/ica/html/trunk/public/…/config/…/  
vendor/plugins/flex\_image/lib/flex\_image/model.rb:161:in `data='n

Obviously it is failing in the data.size \>0 line in the data= method.  
But shouldn’t the require\_image\_data=false fix that. I mean how is it  
creating models without images. I looked in the log and the sql is  
setting data = NULL. I tried that in the controller and it failed.

Any Ideas on what I should do?

Thanks, K
