Length cannot be less than zero. Parameter name: length

This might appear to be weird to you as it is for me but i don't find any solution :|

It happens like this:

Go to content on template insert a macro and then save an publish. Everythinks is fine.

Reopen and save -> throws an error:

Length cannot be less than zero.

Hi Adrian,

I can't seem to reproduce this but it does seem to be a common issue. Here's the bug on codeplex (please vote it up). http://umbraco.codeplex.com/workitem/30620

How are you reproducing this - what browser, what content does your macro contain, etc? If reproducable maybe we can submit the code on that workitem as a pull request :)

Hi Adrian,

I also encountered this annoying little critter last night. I'm using umbraco v 4.7.2 (Assembly version: 1.0.4500.21031)

After messign around with it for a while, I discovered finally this morning that if I set Render content in editor within the macro settings to No then the problem seemed to go away.

A pathetic little work around, but at least I was able to move on. Hopefully it may assist you and/or your users as well

Cheers,

Cameron

I too had this issue last week and the only workaround I found was also to disabled rendering of macro content in the RTE. What little debugging I did leads me to believe the issue is content related (rendered content) rather than an actual bug in Umbraco.
