value="<c:out value='${MyBean.myValue}' />">

key="jsp.form.booleandropdown.true" bundle="JSP_LABELS" />
| <html:option value="false"
key="jsp.form.booleandropdown.false" bundle="JSP_LABELS" />

This is just a guess, but you could try writing it like this:
<html:select name="MyBean" property="myValue" value="${Mybean.myValue}">
...
</html:select>
I think the problem is the c:out tag in the value attribute. In any
case, you don't need it. You can use EL expressions anywhere if you are
using a container that supports the JSP2.0 specs.
