The info statements in Zoho Deluge can be helpful for debugging.  However, they convert newlines to spaces before being posted.

In my case, I had some old records with a field that was accidentally multi-valued.  I wanted to get the last instance of the value.  In the records and in info statements, those values all looked like they had spaces between them.  If I copy/pasted out of the record or info statements, they had spaces between them.  However, those weren't actually spaces, they were newlines.

Example code:

productVersion = product.get("Version_Code");

info productVersion; //returns "2416 2416"

info productVersion.contains(" "); //returns "false"

I tried find, indexOf, lastIndexOf, contains, and several other commands before I realized the problem.

I don't know that there's anything to be done about this.  I understand the convenience of seeing the string on one line instead of trying to display a multi-line string.  I am just posting this in case anyone else wonders why Deluge cannot find the space that it just said is in the string.
