Does <isPropertyAvailable> work with <select parameterClass="java.util.Map"> and null values? I expected that if I set a property to null in a HashMap, that <isPropertyAvailable> would be true for that property, because the key is in the map even if the value is null. But instead <isPropertyAvailable> is false for this scenario. Is this the expected behavior? If so, then how is <isPropertyAvailable> different than <isNull>. Am I misunderstanding it's use? Thanks. _________________________________________________________________ Put your friends on the big screen with Windows Vista® + Windows Live™. http://www.microsoft.com/windows/shop/specialoffers.mspx?ocid=TXT_TAGLM_CPC_MediaCtr_bigscreen_102007
