client side validation for css_xhtml fails when using required="true"
---------------------------------------------------------------------
Key: WW-3283
URL: https://issues.apache.org/struts/browse/WW-3283
Project: Struts 2
Issue Type: Bug
Components: XML Validators
Reporter: David Stuart
Within the validation.js file for the css_xhtml theme the function
findWWCtrlNode(enclosingDiv ) uses the code....
for(var elem in enclosingDiv.getElementsByTagName("div")) {
to find either div's or later span's. This code only returns undefined
responses and therefore always returns the final line of code within the
function...
return enclosingDiv.getElementsByTagName("span")[0];
This returns null if the user hasn't set required="true" within the taglib but
will return the span used for showing * in red as a required field otherwise.
This means that the new inserting error div generates a javascript error....
Possible solutions...
1. Change the loop to actually find the classes it is searching for
var e=enclosingDiv.getElementsByTagName("div");
for(var i=0;i<e.length;i++) {
if (e[i].className && e[i].className.match(/(wwlbl|wwctrl)/))
return e[i];
}
2. add a span into the generated css code so that when the final line of code
searches for the first one it find one that it can inssert the error code into
3. return nll if no div's or spans are found
Cheers
Dave
