It seems that when using TAB and maybe ENTER in a field of a block, like change label text, or changing the value of an objects field, when pressing tab to go to the next block, or enter to finalize the edit, the system is entering an invisible line break or tab space.
When not using trim space for a variable i made, this line of code breaks, returning a null for the row information. This is not a caps sensitive issue or visible space in the text.
