I wrote some time ago (in this post) about a patch for some issues with the layout in the BPMN process editor in 18.104.22.168. I know that a lot of folks have contacted Support to ask for the patch that I mentioned in that post, and I know that some of you were told by Support that there was no patch available.
We have worked with Support to fix this problem, and I am happy to say that the patch is available to download from Oracle Support now. I hope you did not have too much inconvenience.
The Patch number is 13088538: NPE IN O.BPM.UI.LAYOUT.MIGLAYOUT:114.
