Claus Ibsen commented on CAMEL-6191:
------------------------------------
Sorry the notification mail got lost for me somehow.
Its very common to use quotes for strings when it contains a space when passing
that in as a single argument, such as on the command shell, java parameter,
other programming languages.
So IMHO requiring to use a quoted string when it has a space is valid for me.
Though I agree we should look into improving the parser to see if we can parse
the expression or predicate as much alike as possible.

> The simple langage permit to access to a map element by specifying the key
> between [], ie ${body[key]}
> When the key contains a space the behavior is not the same for a simple
> expression or a simple predicate:
> * expression ${body[my key]} will access to the "my key" element -> correct
> * expression ${body['my key']} will access to the "my key" element -> correct
> * predicate ${body[my key]} == 'value' will access to the "mykey" element ->
> incorrect
> * predicate ${body['my key']} == 'value' will access to the "my key" element
> -> correct
> {noformat}
> See attached testcase, the current ouput is
> {noformat}
