JavaScript Error when dragging block to mashup editor

I've been getting the following error all afternoon whenever I drag a block to the mashup project:

Line: 68

Char: 11530

Error: 'blockMetadata' is undefined

Code: 0

I've repro'd this issue on both XP and Vista (two different computers) and with a fresh Sliverlight Beta install.

I"m getting the same error. This showed up in 'most' of the blocks and mashups I tried including once that worked fine yesterday morning and since these have not changed I think it is a change with Popfly...? Please help if any one knows what is up with this...

Which block are you dragging?

Pretty much any of the blocks.

RSS, Twitter, Virtual Earth....the error occurs while the "loading" is displayed. I'm also seeing the error when I try to view my saved copy of the tutorial mashup.

We we tried this on another machine and the blocks that do not work on my box do work. on his. an example is this mashup example:

and the same control without the popfly bits works fine at:

So at least I know its not the silverlight persay or the script but maybe something todo with being an XP box I'm using? or IE 6 it seems?

Thanks for the bug reports it seems that one of the servers in rotation was using older bits and thus some files weren't present or were out of date. Were doing a test run at the moment but so far it seems ok.... (but of course that issue could just be hiding more ;-) so says the cynic in me!)

<fingers crossed>

Andy:

I cleared my Temporary Internet files and reloaded the page and now everything seems to work for me again. Thanks.
