asterisk users - Dec 2008 - Troubles with AEL

Hi,

I'm migrating some macro from extension.conf format to AEL and they are
some things
i don't understand, and some i don't evan know how to get them working.

Example:
    Doing this "queueMemberList=${QUEUE_MEMBER_LIST(queue)};" 
won't
make any warning
        message, however the resulting variable value won't be the
expected one (a string) but some kind of number

    However this work: Set(queueMemberList=${QUEUE_MEMBER_LIST(${queue})});
       Is there a reason ? i have the same comportement with CUT()

Also, there is this construct which isn't working:
            if( ${DB_EXISTS(family/key)} ) {
            } else {
            }

However i can't find a workaround in this case ... any idea ?

Well, never mind ths one, some space got stuck in the macro calling,
giving a wrong key at this point ....

Set works because it is translated directly into the dialplan;

queueMemberList=${QUEUE_MEMBER_LIST(queue)};

is translated into queueMemberList=$[${QUEUE_MEMBER_LIST(queue)}]
(note the $[] added), which is probably not what you want in this 
case, but would be fine if you wanted the RHS to be evaluated...

a = ${b} + ${c};
