Selecting Topology tab gives null pointer exception.

[ghost]

This happens everytime I select the topology tab. This started after a backup restore. I backed up my raspberrypi mycontroller and restored it to a computer running ubuntu. Both running the same version of mycontroller.org

MyController Version 1.2.0.Final Database schema revision 1.04.01 - 2017 Oct 25 Database type H2 database embedded Database version 1.4.194 (2017-03-10) Git commit:branch a10694ff1bff40cfb9988cec48e6569ec51ee57b:master Built on 2018-02-23T10:26:25+0530 Build JDK 1.8.0_161 Build tool Apache Maven 3.5.0 Java virtual machine specification VM vendor Oracle Corporation VM name Java HotSpot(TM) 64-Bit Server VM VM version 1.8.0_171-b11 Java home /usr/lib/jvm/java-8-oracle/jre Operating system Operating system Linux Architecture amd64 Version /Kernel 4.15.0-22-generic Location /home/john/mycontroller/mycontroller/
