In BaseX v11.6 an error occurs when passing a value via "%rest:form-param" in combination with a security function.
The example below consists of two RESTXQ functions "p:post" and "p:form". After submitting the form with a value for input "resource-id" the following error occurs in function "p:post":
Stopped at /usr/local/basex/webapp/ui/problem.xqm, 16/10: [basex:restxq] Value of "resource-id" must be xs:string, supplied: ().
Example module problem.xqm:
module namespace p = 'problem';
declare %perm:check('/p', '{$perm}') function p:check( $perm as map(*) ) as element(rest:response)? { };
declare %rest:path('/p/post') %rest:POST %rest:form-param("resource-id", "{$resource-id}") %output:method('html') %output:version('5.0') function p:post( $resource-id as xs:string ) { <div> <p>$resource-id={$resource-id}</p> </div> };
declare %rest:path('/p/form') %rest:GET %output:method('html') %output:version('5.0') function p:form() { <div> <form method="post" action="/p/post"> <input type="text" name="resource-id" id="resource-id" required="required"/><br/> <button type="submit">Ok</button> </form> </div> };
The described behavior is caused by the security function "p:check".
1. If you remove the security function "p:check" it works fine. 2. If you replace `%rest:form-param` with `%rest:query-param` it also works fine, but that doesn't seem right to me.
Is this a bug or do I something wrong?
Kind regards, Jan Meijer
