The initial idea was to send the data if there is no error anymore. E.g. there is no internet connection, thus the data engine reports an error. Now if there happens to be an internet connection the data engine automatically trys again and then sets the data. As the applet is still connected it would then get the comic. The disadvantage of this approach is that I do not specify which type of error happened in the datasource. Thus it might very well be that it will be never taken care of. > On April 7, 2011, 2:43 p.m., Aaron J.

Yes. I thought it to be nicer that way but as you said it is not needed. - Matthias ----------------------------------------------------------- This is an automatically generated e-mail.
