Bug Report: java.lang.String cannot be converted to java.lang.Long in JSF EL Expression #21

Open kamilkrzywanski opened 1 week ago

kamilkrzywanski commented 1 week ago

When using a 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: https://github.com/eclipse-ee4j/expressly/commit/704050fa638a44254e5e0975083ef9489586f995#diff-2ff982307127640577acb628d13e962081390439c5f3a62d694d09a42a1dfdd2L116
