Ignoring variable change for non-existent component - Exception

Hi everybody,

my application is using the openstreetmap extension to show some points on a map.

after selecting a vector i get this exception:

com.vaadin.terminal.gwt.server.AbstractCommunicationManager handleVariableBurst
WARNING: Warning: Ignoring variable change for non-existent component, VAR_PID=PID332 

can somebody help me to solve this problem? where can i get more informations about this error? Maybe where it is fired or which variable is causing the fault?!

thank you

nobody?!
