Greetings, i used custom plugin in TC8.3 which included com.teamcenter.rac.util.viewer.ViewerPanel class from com.teamcenter.rac.util_8000.3.0.jar Then we've migrated to TC10.1 and there is com.teamcenter.rac.util_10000.1.0.jar which has no class com.teamcenter.rac.util.viewer.ViewerPanel. I've found class looks similar in com.teamcenter.rac.common.tcviewer.ViewerPanel but there are some difference between them. For example there is no setComponent method. What should i do now? Does old class was moved somewhere else or should i rewrite plugin with a new class (then what about setComponent method)?
