             Summary: EL syntax error: Expecting Expression on EL string concat operator
                 Key: JBIDE-23891
                 URL: https://issues.jboss.org/browse/JBIDE-23891
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: jsf
    Affects Versions: 4.4.2.Final
         Environment: Windows 10
Eclipse Neon.2 (4.6.2)
JBoss Tools 4.4.2.Final (Marketplace)
JavaEE 7
            Reporter: thatsIch thatsIch
            Priority: Minor


The EL 3.0 specification [1] states

String Concatenation Operator - A += B
To evaluate A += B
■ Coerce A and B to String.
■ Return the concatenated string of A and B.

Used on a JSF Tag like

{code:java}
<h:outputText value="#{'foo' += 'bar'}" />
{code}

leads to following warning:

*EL syntax error: Expecting expression.*

on the *=* part of the *+=* operator.
