I'm using the following component: link In the same way as shown in the example, but in a modal bootstrap ..
The problem is that my Spinner does not appear the Up and Down buttons, browsing in my code I saw that when I remove the following include the buttons appear:
<script src='${pageContext.request.contextPath}/JS/bootstrap/bootstrap.min.js' charset="utf-8"></script>
I do not know what can be, some kind of conflict probably follows an image when debugging ..
