Whenever doing <c:set var="emp"><cq:text property="empid" /></c:set> is always giving me string. But var suppose to return 'int'. Is there any any to get 'int' instead of 'string'
Thanks

You can use the <fmt:parseNumber> tag, which is already available in CQ5 (the <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> library is referenced by global.jsp) and which is a good thing to do to avoid scriptlets. This example is detailed at http://www.tutorialspoint.com/jsp/jstl_format_parsenumber_tag.htm:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<html>
<head>
<title>JSTL fmt:parseNumber Tag</title>
</head>
<body>
<h3>Number Parsing:</h3>
<c:set var="balance" value="1250003.350" />
<fmt:parseNumber var="i" type="number" value="${balance}" />
<p>Parsed Number (1) : <c:out value="${i}" /></p>
<fmt:parseNumber var="i" integerOnly="true"
type="number" value="${balance}" />
<p>Parsed Number (2) : <c:out value="${i}" /></p>
</body>
</html>
This would produce following result:
Number Parsing:
Parsed Number (1) : 1250003.35
Parsed Number (2) : 1250003
You are using the
<cq:text>tag which is per se a string. Try the following:If the property is a number in CRX this should return a number as well. Else you would need to use a scriptlet to read the property type safe:
