WDPortalEventing.fire events problem

Friends,

In my webdynpro application,i do the following.

In a button eventhandler, i fire 2 <b>WDPortalEventing.fire</b> events.

At runtime ,receiving iview has subscriped for both events.

I am receiving the last fired event first.Is this bug or it suppose to work like this?.

According to the SAP documentation we can fire as many as events in a request-response cycle.But i havent seen any document descriping about the behaviour of execution.

Could anybody help me on this ??
