Config change template truncates commands (Juniper)

I have a config change template to generate MAC and ARP xml files on Juniper EX switches. Here's the pertinent snippet:

script GetARPandMACJuniper(
                                           NCM.Nodes @ContextNode,
                                           string @ARPfile,
                                           string @MACfile
                        )
{
CLI
{
     show arp | display xml | tee @ARPfile
     show ethernet-switching table | match ge- | display xml | tee @MACfile
     exit
}
}

When I execute it on a switch it shows the commands as:

display xml | tee @ARPfile
show ethernet-switching table | match ge- | display xml | tee @MACfile
exit

If I flip the command order, whichever one is on top will be trunkated to the first pipe, but the one below will be fine. I tried adding a trivial command to the top as well and the first section preceeding a pipe gets truncated.

For instance:

{
     show ethernet-switching table | match ge- | display xml | tee @MACfile
     show arp | display xml | tee @ARPfile
     exit
}
}

Becomes

     match ge- | display xml | tee @MACfile
     show arp | display xml | tee @ARPfile
     exit

And this:

{
     clear system commit
     show ethernet-switching table | match ge- | display xml | tee @MACfile
     show arp | display xml | tee @ARPfile
     exit
}
}

Becomes

     clear system commit
     match ge- | display xml | tee @MACfile
     show arp | display xml | tee @ARPfile
     exit

Thinking it might be just a display glitch in the Orion console I run it and it only generates the second file and shows a transfer error in Orion.

I can "fix" it by adding a pipe at the beginning of the first line with pipes. This generates both files but still shows a transfer error.

The "fix"

{
     | show arp | display xml | tee @ARPfile
     show ethernet-switching table | match ge- | display xml | tee @MACfile
     exit
}
}

This is mildly infuriating. Any ideas why this might be happening?

Thanks.

I got it figured out...or a work around...either way it works. I added the string to a variable. Learned this working on another issue.

| show arp | display xml | no-more | tee @ARPfile

Becomes

string @ARPfile = 'show arp | display xml | no-more | tee ' + @IDF + '-arp.xml'

I no longer declare the @ARPfile at the start of the script within the () and now only declare @IDF (and another one for another cli function).

Here's the pertinent part of the script block, you have to retain whitespace in the script for this to work.

script GetARPandMACJuniper(
                                            NCM.Nodes @ContextNode,
                                            string @IDF
                        )
{
string @ARPfile = 'show arp | display xml | no-more | tee ' + @IDF + '-arp.xml'
string @MACfile = 'show ethernet-switching table | match ge- | display xml | no-more | tee ' + @IDF + '-mac.xml'
{
{
CLI
{
   @ARPfile
   @MACfile
   exit
   }
}
}
}
