Bug Report: java.lang.String cannot be converted to java.lang.Long in JSF EL Expression

[kamilkrzywanski]

When using a <c:if> tag with a JSF Expression Language (EL) expression that performs a numeric operation, such as:

<c:if test="#{testView.string == 56 * 1}">
</c:if>

The following error is thrown:
Cannot convert [Welcome to PrimeFaces!!!] of type [class java.lang.String] to [class java.lang.Long]
Here, testView.string is a String property (Welcome to PrimeFaces!!!), and the comparison with a numeric expression 56 * 1 leads to a type mismatch.

Probably regression commit:
