Servoy_blobloader() is not updated until restart

Classic Servoy
1

If I change an image in a blob field the servoy_blobloader function does not retrive the new version of the image until the servoy client or the developer running the application is not restarted.

Same behavior on Sybase and mysql
Same behavior with 2.1.2 and 2.2 beta 2

Is it a known problem?

Thank you in advance

Images are cached by the html renderer as long as the URL is the same, to over come this add a random nummer to the url, like:
<normal_blob_loader_url>&rnd=<a_rnd_number>
