This is a documentation problem: value is not legal for setCheckBox. You should use checked="true/false".
Also WebTest.dtd is wrong:
<!ELEMENT setCheckbox ( #PCDATA )* >
<!ATTLIST setCheckbox
...
value CDATA #REQUIRED
I replaced: value="1"
with: checked="true"
However, the error message still remains the same.
Is it possible that you have many inputs with this id in the page (what would be incorrect)
The id is unique. There are not several inputs with the same id (see attached HTML file)
Just tested without problem a minimal test on the file you attached.
Are you sure to be on the right response?
Sorry, yes I wasn't on the right response.
Will the DTD and doc be corrected in 2.5?
As of version 16269, which is HEAD for 2.5, value, if available, _is_ used to select the desired checkbox.
But the value should be optional.
Documentation corrected in R_1565.
