yeah, the spec is unclear on this point. I have tried this and it doesnt have the desired behaviour: <jsp:SetProperty name="RequestParmBean" property="inputfieldA" value=""/> This will not set inputfieldA to an empty string. Does anyone know why they implemented it in this way?
I think it was for consistency with the auto-population model, i.e., when using property="*". But, the result is very confusing, I agree.
This should work, though, since a request-time attribute value is used as-is:
<jsp:setProperty name="RequestParmBean" property="inputfieldA" value='<%= "" ' />
or to set it to null:
<jsp:setProperty name="RequestParmBean" property="inputfieldA" value='<%= null ' />
Typos. I meant:
<jsp:setProperty name="RequestParmBean" property="inputfieldA"
value='<%= "" %>' />or to set it to null:
<jsp:setProperty name="RequestParmBean" property="inputfieldA"
value='<%= null %>' />Messy ... An alternative is to use JSTL's <c:set>:
<c:set target="${RequestParmBean}" property="inputfieldA" value="" />

If I am reading the spec correctly, you can initialize all of your properties individually prior to setting them from the request params. I believe that the line you quoted from the spec only applies when setting properties from request params.
eg: <jsp:SetProperty name="RequestParmBean" property="inputfieldA" value=""/> <jsp:SetProperty name="RequestParmBean" property="inputfieldA" param="inputfieldA"/>
or, assuming an input form the "inputfieldA" and "inputfieldB": <jsp:SetProperty name="RequestParmBean" property="inputfieldA" value=""/> <jsp:SetProperty name="RequestParmBean" property="inputfieldB" value=""/> <jsp:SetProperty name="RequestParmBean" property="*"/>

Hi
Using <jsp:setProperty...> is is possbible to set empty strings? and if so how?
I realise the spec says: "If the parameter has an empty or null value, the corresponding Bean property is not set. "
but can anyone reccommend a fix?
thanks in advance.
