<tt>Hi Brett,<br>
<br>
The missing value warning is fixed on SVN.<br>
<br>
I was also trying to fix the concat issue, but not able to
reproduce it. I tried 2 different cases:<br>
<br>
$json(var1) := '{"string1":"String1data"}';<br>
$json(var2) := '{"string2":"String2data"}';<br>
<br>
$avp(result) = $json(var1/string1) + $json(var2/string2);<br>
<br>
xlog("result is <$avp(result)> \n");<br>
<br>
<br>
or<br>
<br>
$json(var1) :=
'{"string1":"String1data","string2":"String2data"}';<br>
$json(var2) := '{"string2":"String2data"}';<br>
<br>
$avp(result) = $json(var1/string1) + $json(var1/string2);<br>
<br>
xlog("result is <$avp(result)> \n");<br>
<br>
<br>
In both cases I got the a valid output....<br>
<br>
Any help with it ?<br>
<br>
Regards,<br>

<tt>Hi Brett,<br>
<br>
So, some initial data:<br>
<br>
The $json variables are (as scope) the same as $var - which
means they have visibility only per process (as names they do
exist in all procs, but they have different instances / values
in each proc), but inside the process they are global - visible
to all messages, from all routes which are executed in that
particular process (!so take care that to reset the json before
usage as you may inherit some value from a previous execution in
the same proc).<br>
<br>
Now, about your cases:<br>
<br>
1) using a $json in extra_db - it is visibility issue - you set
the json var for INVITE (in a process) and you try to read it
for the BYE (in a different proc). Actually the error you get
says that you try to read a $json which was never set.<br>
<br>
2) using it from failure / onreply routes - same as above.<br>
<br>
<br>
Which leaves us with 2 real bugs:<br>
<br>
1) when merging 2 jsons - the bogus len - we will look into it<br>
<br>
2) the errors on missing values or tags - I will change them to
DBG and to actually return NULL value to script.<br>
<br>
Thanks and regards,<br>

<div>Also. $json variables don't survive to onreply routes or
failure routes. And they can't be used in db_extra. There also
isn't a real good way to reliably check for the existence of a
json element without throwing an error in the log</div>
