Exception EL Expression Unbalanced:

Question

I am using JSF in my web application. I am passing parameters from my composite component to bean, but I am getting EL expression Unbalanced exception. Below is the code I am trying to use:

<h:panelGroup binding="#{datatableManagedBean.getDynamicDataTableGroup(#{cc.attrs.id})"/>

But I am getting below exception

javax.el.ELException: EL Expression Unbalanced: ... #{datatableManagedBean.getDynamicDataTableGroup(#{cc.attrs.id})
    at com.sun.faces.facelets.el.ELText.findVarLength(ELText.java:476)
    at com.sun.faces.facelets.el.ELText.parse(ELText.java:396)
    at com.sun.faces.facelets.el.ELText.parse(ELText.java:347)
    at com.sun.faces.facelets.el.ELText.parse(ELText.java:338)
    at com.sun.faces.facelets.el.ELText.isLiteral(ELText.java:321)
    at com.sun.faces.facelets.tag.TagAttributeImpl.<init>(TagAttributeImpl.java:127)

What can I try next?

Answer 1

Don't use EL expression inside another EL, you also forgot to close the first EL

Use this and notice the diff

#{datatableManagedBean.getDynamicDataTableGroup(cc.attrs.id)}

Answer 2

The error will be logged even when the '}' is missing. Something like:

<c:forEach items="#{customerRegistrationBean.accountWebData.selectedAccount" var="account">
