Problems with checkbox using Struts Validation

1) I want my DynaValidator to validate the input:text only if it is not empty and the checkbox is not checked, but I can't find the right expression for the "validwhen" property. Actually it is:
<field property="text_name" depends="validwhen">
<arg0 key="myform.mytext_name" />
<var-value>((checkbox_name == null) and (*this* != null))</var-value>
but i don't know how to validate the ""
2) when validation fails, the validator calls back the page. The checkbox will still be checked, but the input:text will not be disabled.
Could you help me? Thanks in advance. David

null will also check for empty string ("")
See the bullet item for null.
"* The value null which will match against either null or an empty string "
