Getting a null problem with a bean:define

[grahamcoleman23]

Ok I'm a bit of a beginner at this. I'm trying to use a bean:define something like this:-
<bean:define id="currentCost" property="currentcost" name="slForm" type="java.lang.Double"/>

I'm getting a "Define tag cannot set a null value' " error in the browser. I realise this is as the define needs to be wrapped in a logic tag, but I'm having problems getting this to work.

I've tried this :-

<logicresent name="slForm">
<bean:define id="currentCost" property="currentcost" name="slForm" type="java.lang.Double"/>
</logicresent>

still no joy, any ideas!

The problem looks like its currentcost thats bombing you, not slForm.

You probably need to check to make sure current cost is valid, something like

<logic:notMatch name="slForm" property="currentcost" value=null>
..define here..
</logic:notMatch>

I did not try that but something like that should work, test the property, not just the name.
