The target type for property mapping is determined by the action method 
argument type. Thus, it is always set to \Something\A. But you can 
optionally pass the type information and the object converter will then 
take care to set the target type accordingly:

<f:if condtion="a.type=tx_..._b">
  	<f:form.textfield property="b" />
	<f:form.hidden name="tx_yourplugin[a][__type]" 
value="\Wall\Domain\Model\B" />
</if>
