Hello Alexander,

It could mean anything depending on what resources you are using for your project, or maybe even the type of files you are handling.  If you could provide a little more information we might be able to suggest a solution:

• what version of Studio are you using?
• are you connecting to any servers?
• what filetypes are you handling (also the version if you know)?
• when in your creation process is this error thrown?
• do you have the error stack?  This is the detail behind the error message which you can find by clicking on the little symbols in the error message.

Thanks

Thanks Alexander,

Based on your subsequent message it seems there is something in the 2010 filetype that Studio doesn't like, so it would make sense to investigate what that might be if we were to find the problem to this error.  If you can share the file I'd be happy to investigate it?

I wish there was a glossary to explain what the message means!

Here's the problem with this.  This error means the code is referring to an attribute that doesn't exist or doesn't have a value.  That in itself, as you can imagine, tells us nothing because it could still be something affecting anywhere in the code.  Would knowing this help you?  Probably not, and it doesn't help us either, as this information on its own is not enough to help find the resolution to where this is, hence the need for more information. Debugging can be quite tricky and the number of different scenarios possible in a filetype is huge, so we can never test them all!  All we can do is narrow down the file until we get to the very thing that is causing the error and then we can fix it.
