I don't understand how it can be throwing this error. The CreateRecurrenceTask does have a setter for task name but I commented out the reference to set the task name in the editor control so it won't try to localize it and should not even be referencing that property. Its working fine on my local copy but that is a newer build of mojoPortal, but still I can't figure out why it would throw this error even using 22.214.171.124 version of mojoPortal.
I'm pretty much ready to release the next version of mojoPortal, I guess I will have to make a release tomorrow and hope it solves this. I apologize for the inconvenience of this issue, its a mystery to me how this is happening.
