> *Problem*
> When event is passed to continuous query filter, it can be used only in scope of this
method. The reason is that if filter returns {{false}}, the method {{CacheContinuousQueryEntry.markFiltered()}}
is called. This method *clears* key and values.
> *Solution*
> We should not clear key and values. Instead, we should properly check for {{FILTERED_ENTRY}}
flag in all methods where {{key/newVal/oldVal/depInfo}} are used. This includes generated
{{readFrom()/writeTo()}} methods as well - their manual change will be required.
