check side conditions of the related column.

from docs:

property onclick as %ZEN.Datatype.eventHandler;
onclick event handler: This event is fired when the mouse is clicked within a cell in this column. If the column does not have data associated with it you will have to set the linkCaption property.
Note that this callback is called before the new row in the table is selected so you will not have the current selectedIndex for the table when this callback is fired. If you need that, use the tablePane's onselectrow callback.

Sample Global Names and Their Uses

The following are examples of the various kinds of global names and how each is used:

2) is a broken call for a label in a routine and has nothing to to with globals

3) looks like a  broken condition on variable a also no globals around

If your connection is not stable enough I'd suggest to take a closer look to good old Shadowing.

It's really jungle proof.
I used it in past to transfer data from an oil drill platform  somewhere out on the ocean over a satellite link with just 64k bd bandwidth without any data loss. And this link was far from whatever you would expect from a wired connection on ground.
Shadowing did id with incredible stability and no loss.
Cascading of shadowing is also almost unlimited with no  issue.

You may take this approach:

create an object based on Schema1: My.Schema1
create an object based on Schema2: My.Schema2

HowTo: => XML Schema Wizzard 
http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...

Then you may use this method.

Method GetCustomerInfo(schema1 as My.Schema1) As My.Schema2 [WebMethod]


My.Schema1 is checked as input parameter according tothe generated class
inside your Method you transform it to My.Schema2
and return it. 

The most tricky thing might be how to reply to a request that doesn't match Schema1.

I'm not an expert on callout but deep back in history I believe to remember that what ever you
transfer is in wider sense a single item. If string structured by $p() or $lb().
You my take a closer look to %XML.SAX.* classes.
The highest structure is $LB(). Which is a string under cover.
And take care of the 32k limit
