Hi, Kay, The start() methods are the same in my version and the one in github. Lines 115-117 are: thread = new Thread(this, "WriteThread"); output.println("time to start: "+ currentData()); thread.start();I guess that the error is in the new Thread line because 116 line is composed of standard library functions (as far as my poor java knowledge helps).
Am i correct or shuld I look if the currentData() is not working fine? Thanks, Zunbeltz az., 2015.eko urtren 07a 14:26(e)an, Kasemir, Kay igorleak idatzi zuen:

(ArchiveEngineConfig seems to run fine). Any idea what can be happening or where should I look? We are runing a modified archiver that stores in hypertable DB.You should check line 116 of WriteThread.java to see what's null. But to do that, you need to use your version of the sources, since you have a modified version of the source code. In the current version of WriteThread, the start() method only spreads lines ~90 .. 100 (https://github.com/ControlSystemStudio/cs-studio/blob/master/applications/plugins/org.csstudio.archive.engine/src/org/csstudio/archive/engine/model/WriteThread.java ) Thanks, Kay
