Claus Ibsen commented on CAMEL-979:
-----------------------------------
The problem is to determine if its an error or not if an end user enters
{code}
in.heder.foo
{code}
That was supposed to be:
{code}
in.header.foo
{code}
Currently you get an Exception.
> SimpleLanguage - to support constant expressions

> Key: CAMEL-979
> URL: https://issues.apache.org/activemq/browse/CAMEL-979
> Project: Apache Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 1.4.0
> Reporter: Claus Ibsen
>
> Currently the simple language does not support constant expressions, that
> actually is useable in the file component that uses simple language to set
> file names
> So if an end-user want to produce a file with a fixed name, then its not
> possible
> {code}
> expression=MyBigFile.txt
> {code}
> Is not possible.
> But this is:
> {code}
> expression=MyBigFile-${header.foo}.txt
> {code}
> is as there is a ${} placeholder and then the simple language can evaluate it.
