Alright! I finally figured out a way around this. I'm all proud cuz this has been pissing me off for a while now. If you don't use the reset method, then you just have to put one tag after your checkbox. AFTER the checkbox tag, put <jsp:setProperty name="beanName" property="prop" value="false" />. This will let the checkbox load normally, then set the property to false after it's loaded, so now all required properties will be correctly updated. Try it out, it works (at least for me). Is this workaround frowned upon by the struts gurus?

The only way around I have found is to use a seperate boolean attribute which will store the "real" value of the checkbox, the other is simply an initial value. For example if I have a check box called "test", then: =============================== // Declare checkbox attributes private boolean testInitial; private boolean test; // One setter method - in it, set public void setTestInitial(boolean newValue) { test = newValue } // Two getter methods, one used by form (testInitial), other used by actions public boolean getTestInitial() { return testInitial; } public boolean getTest() { return test; } // Reset method, always set test to false, set testInitial to whatever you want public void reset() { testInitial = true; test = false; } ================================ And in your form, we should have: <html:checkbox property="testInitial"/> =============================== Your action class should use the getTest() method to get the actual value of the checkbox submitted. It will appear on the form as checked, but the value actually being used is false. If it is left checked, it will call getTestInitial() which will set the real value (test) to true, if not, it will remain false. I asked a question yesterday about the fact that if the validation fails, then it doesn't show the actual values of the checkbox when the form re-appears to show the error messages, since testInitial is always true. Although its not a big issue, does anyone know a way around this? Hope this helps anyhow!
