[xmlblaster-devel] XmlBlaster internal error

["Dmitriy Kolasnikov" <dkolasnikov at btrade.com>]

Hello,

The following error has occured when I was trying to publish a message. 
Basically, I was running HelloWorldPublish with the persistent mode on and the same session ID on every connection. After being abnormally terminated several times, the subscriber was up and running. I decided to restart the HelloWorldPublish and the error occurred right after the the TopicProperty has been added on the first publish.
