Loading of file.xml failed. Cannot read the array length because "this.patternIndex" is null.

I get the following error message whenever I create an .xml file in BEAUti and then I try to open it up again for further editing: Loading of file.xml failed: Cannot read the array length because "this.patternIndex" is null. Cannot invoke "org.w3c.dom.Node.getNodeValue()" because the return value of "org.w3c.m.NamedNodeMap.getNamedItem(String)" is null". This only happens when the .xml was created with a partitioned NEXUS file with multiple genes. BEASTLabs is installed and updated on my 2024 MacBook Pro. Could you help me out? Thank you in advance.

@mrmancuso thanks for the bug report! Unfortunately, I have trouble replicating the problem. If I do the following:

• open BEAUti and import Primates.nex from the BEAST.app/examples/nexus folder. This has 2 partitions.
• link trees and clock models
• save the XML
• restart BEAUti and load the XML

there is no problem or error message. Can you give more details on what you did before the error appeared? Cheers, Remco
