License validation error

(Bernhard Zoellich) #1

I have a ASPNet application using Hydra 4 that every once in a while (I have not been able to determine the circumstances) produces the error below. Hydra is fully licensed and this error does not occur on other sites running the same application.

System.Web.HttpUnhandledException (0x80004005): Exception of type ‘System.Web.HttpUnhandledException’ was thrown. —> System.ArgumentException: Item has already been added.

Thanks, logged as bugs://78525

This looks like a race condition on first plugin activation. As a workaround try to instatiate this plugin once at app startup

This issue will be resolved in the next Hydra Beta build.

Sorry for the inconvenience.

Thanks, I will give it a try.

Will this fix be available for Hydra 4?

Most probably no. Current version is 5 so all fixes go to it.
