c:when and c:if don't work

I can access my variable stored in a backing bean from my JSF2 page, so things like

<h:outputText value="#{myBean.myValue}"/>

work, and the value (which is an int btw.) prints okay. However, when trying to use this value in conditional expressions within c:if and/or c:when tags it never equals anything... so:

<c:if test="#{myBean.myValue == 1}">
    <c:set var="myVar" value="true"/>
</c:if>

<c:choose>
    <c:when test="#{myBean.myValue > 1}">
        <c:set var="myVar" value="true"/>
    </c:when>
</c:choose>

or even

#{myBean.myValue eq '1'}

#{myBean.myValue == '1'}

will never evaluate to true, even if the value is indeed 1 or >1.

Annoyingly the comparison works in the rendered attribute of a tag! So this:

<h:outputText value="whatever" rendered="#{myBean.myValue == 1}"/>

is fine!

What is going on?

UPDATE:

This works:

public int getMyValue() {
    return 1;
}

but this does not:

@Column(name = "orderstatus")
public int getOrderStatus() {
return orderStatus;
}

The int's value is printed correctly, but 1 == 1 is false.

Are entity beans handled in a special way? Can I use them for displaying their value on the UI?

UPDATE2:

<h:outputText value="#{order.adcOrderStatus.orderStatus.class}"/>

prints java.lang.Integer.

UPDATE3:

Here is the full code:

                <c:set var="unknownStatus" value="false"/>
            </c:when>
            <c:when test="#{cc.attrs.orderStatus == 2}" >
                <c:set var="unknownStatus" value="false"/>
            </c:when>
            <c:when test="#{cc.attrs.orderStatus == 3}" >
                <c:set var="unknownStatus" value="false"/>
            </c:when>
            <c:when test="#{cc.attrs.orderStatus == 99}" >
                <c:set var="unknownStatus" value="false"/>
            </c:when>
            <c:otherwise>
                <c:set var="unknownStatus" value="true"/>
            </c:otherwise>
        </c:choose>
        <h:graphicImage url="#{resource['img/icons/flag_yellow.png']}" rendered="#{cc.attrs.orderStatus == 1}"/>
        <h:outputText value="Created" rendered="#{cc.attrs.orderStatus == 1}"/>
        <h:graphicImage url="#{resource['img/icons/flag_orange.png']}" rendered="#{cc.attrs.orderStatus == 2}"/>
        <h:outputText value="Stopped" rendered="#{cc.attrs.orderStatus == 2}"/>
        <h:graphicImage url="#{resource['img/icons/flag_green.png']}" rendered="#{cc.attrs.orderStatus == 3}"/>
        <h:outputText value="Active" rendered="#{cc.attrs.orderStatus == 3}"/>
        <h:graphicImage url="#{resource['img/icons/flag_red.png']}" rendered="#{cc.attrs.orderStatus == 99}"/>
        <h:outputText value="Failed" rendered="#{cc.attrs.orderStatus == 99}"/>
        <h:graphicImage url="#{resource['img/icons/question_mark.png']}" rendered="#{unknownStatus}"/>
        <h:outputText value="Unknown" rendered="#{unknownStatus}"/>
    </cc:implementation>
</html>

It works when called with an int value. But this doesn't work:

    <p:dataTable value="#{cc.attrs.orders}" var="order">
        <p:column>
            <f:facet name="header">
                <h:outputText value="Status"/>
            </f:facet>
            <mytag:orderStatus orderStatus="#{order.adcOrderStatus.orderStatus}"/>
        </p:column>
    </p:dataTable>

This displays the correct value:

<h:outputText value="#{order.adcOrderStatus.orderStatus.class}"/>

c:when and c:if don't work
