Subject [jira] [Commented] (CAMEL-6191) Simple expression and predicate behaviors are different when accessing to map with a space in the key
Date Tue, 02 Apr 2013 12:43:15 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-6191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13619753#comment-13619753

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}
