You cant set a primative to null.. You can define a null default like this in your parameter map <result property="description" column="DESCRIPTION" nullValue=""/>

My problem is that one of my properties in my vo is a float type (or any primitive numeric type for that matter) and the corresponding db column returns null from the query. This acutally caused ibatis to throw an error in com.ibatis.common.beans.ComplexBeanProbe.java on setProperty() { method.invoke(object, params); } Here it's trying call method setBlaBlah(float f) via reflection and passing params (params is null, in this case.) Since setBlaBlah() takes in a primitive float type, passing a null causes it to throw an error. My question is has anyone run into this problem and how did you fix it? My temp work around is to modify that class by first checking if params is null. If it's null, don't set the property. But this created another undesired side-effect. when my vo is instantiated, the float property is initialized to 0.0, which is how Java does things, since setBlaBlah(float f) never got called , now that property shows up as 0.0 instead of nothing. Any comments/suggestions are greatly appreciatged. Thanks. stan __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
