Error when associating template to a data query

[eberkut]

Hi,

I'm in the process of writing a fairly large template using SNMP data queries. I modeled my XML file on the interface.xml. I also try to follow religiously Gandalf's excellent howto.

At first I was planning to do exactly the same thing that what done for interface statistics, meaning one data query with several associated graphs. Everything went fine until I tried to associate a first graph. Under 'Associated Data Templates', where I should find a dropbox, I get the following error:

Warning: Variable passed to each() is not an array or object in /var/www/html/data_queries.php on line 356

I've tripled checked my XML file and could'nt find any syntax error. Maybe someone more familiar with Cacti can tell me what this error means exactly and where does it stem from.

Best regards,

[gandalf]

Please state your cacti version.
Then, please post a screenshot of the Graph Template and Data Template

In the zip attached, I put a screenshot of the error, two of the data template and two of the graph template. I also put the SNMP data query XML file.

I'm really puzzled since I tried to do exactly the same thing that was done for interface statistics.

Thank you for your help gandalf.

Please replace </psClassReTxBytesCount> with </psClassReTxByteCount>(see the additional "s"?) in the XML file

Yup, I figured it out yesterday on my way home in the train. I'll test it today.

Thank you anyway for your help Gandalf. And by the way, great work with the docs.
