I recently developed a couple of custom popfly blocks in order to create a popfly mashup (you’ll learn more about it this weekend ;-)).
During development I spent quite some time figuring out why although I was making changes to my blocks, these changes weren’t instantly reflected on my mashup. Then it stroke me, popfly mashups use the latest opened block version. Any changes made to a block after mashup was closed won’t be reflected on it.
This can be troublesome for someone that has developed his own blocks as you’ll have to open and save all mashups that use these blocks anytime you make a change. But imagine being a third party block consumer, you wouldn’t like having your mashup broken just because someone else decided to change his block now would you?
It’s all about tradeoffs I guess…
