Hello all,

if have a weird problem concerning the if/EL expression syntax.

I have a index.zul which lookes like
<?xml version="1.0" encoding="UTF-8"?>
<window title="MyWindow" width="100%" id="main">
<caption>
<toolbarbutton label="login" unless="${$user}">
</toolbarbutton>
</caption>
unnless="${user}"/>
</window>

$user is a session scope value which is a backend class implementation. Everything works fine so far.

If i add an include statement so that index.zul looks like

<?xml version="1.0" encoding="UTF-8"?>
<window title="MyWindow" width="100%" id="main">
<caption>
<toolbarbutton label="login" unless="${$user}">
</toolbarbutton>
</caption>
<-- THIS IS THE NEW IMPORT -->
<include src="/login.zul" unless="${user}"/> </window>

I get an exception:

com.potix.zk.ui.UiException: javax.servlet.jsp.el.ELException: Attempt to coerce a value of type "org.syracus.colab.realm.User" to Boolean

Is there something wrong or does the if attribute behave differently in different components ?

greets Sebastian
