GetFirstItem and the apparent 255 item limit

So, I have a form with over 255 fields on it (it’s a beast, I know) and I noticed that the GetFirstItem method does not work if the item you want was past the 255th item listed in the debugger. Has anyone else noticed this? I could not find any documentation anywhere on the limitations of GetFirstItem if you have over 255 items.

I rewrote the code to use GetItemValue and Implode to get the text string I wanted, In case anyone else runs across this.
