> removeOptions will not remove some select option
> -------------------------------------------------

> Key: WW-3182
> URL: https://issues.apache.org/jira/browse/WW-3182
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.1.6
> Environment: Struts2.1.6 + Tomcat 6.0.20 + Firefox 3.5
> Reporter: Gene Wu

> Fix For: 2.2.0

> removeOptions is incorrect.
> /struts/struts2/trunk/core/src/main/resources/org/apache/struts2/static/inputtransferselect.js
> for example we have a list of {1,2,3,4,5,6}, among it, we select 2,3,4. Click
> remove button. It will left some of them. The reason is
> function removeOptions(objTargetElement) {
> for(var i=0;i<objTargetElement.options.length;i++) {
> if(objTargetElement.options[i].selected) {
> objTargetElement.options[i] = null;
> }
> }
> }
> before you remove "2" from this list. the length is 6. the i will be 1
> after removing "2", in the next iteration, i will be 2, but now the option[2]
> point to the 4. Apparently, "3" was left!
> my workaround is:
> function removeOptions(objTargetElement) {
> for(var i=0;i<objTargetElement.options.length;i++) {
> if(objTargetElement.options[i].selected) {
> objTargetElement.options[i] = null;
> i--;
> }
> }
> }
> correct me, if I was wrong.
