Error when result-name contains a ${} expression

[Jacopo Cappellato]

Hi Adrian,

we have noticed that the following instruction:

            <field-to-result field="val" result-name="${key}"/>

(from ContentServices.xml) returns an error in the console:

2012-05-14 14:12:02,679 (default-invoker-Thread-11) 
[FlexibleMapAccessor.java:163:ERROR] UEL exception while setting value: 
javax.el.ELException: Error parsing '${}': syntax error at position 2, 
encountered '}', expected 
<IDENTIFIER>|<STRING>|<FLOAT>|<INTEGER>|'true'|'false'|'null'|'-'|'!'|'not'|'empty'|'(',
 original = ${key}

However it seems that the value is still returned properly. Any idea of how we 
could fix it?

Thanks,

Jacopo
