In upgrading from Lucee 5.2.1.9 to either 5.2.2.68-RC or 5.2.2.70-RC, I get the following error message in a function that is trying to parse some XML. If I downgrade to 5.2.1.9, things work again without errors.

I coludn’t able to reproduce the issue in 5.2.2.70-RC version. XML parse works fine. I’ve added my test zip file in [LDEV-1430] - Lucee.

I added to the code you provided to reproduce the issue. The bug occurs when trying to use array related function on an XmlChildren node.

I had been using the xmlToStruct function (various versions at Converting XML to JSON - My exploration into madness... and GitHub - GiancarloGomez/XmlToStruct: Updated Script CFC which was originally written by Anuj Gakhar - http://xml2struct.riaforge.org/) , which I imagine some other CF developers are also using.

FYI, this issue occurred before in a much older build and then disappeared in a release version. It seems to have cropped up once more in these builds…

Thanks,
