I have three xls sheet appender appenders working in the same file. I've linked them up so they are executed in sequence, not parallel. However i can't get them to execute. Sometimes one of them gives an error message sometimes all three. Here is what the webportal gives as an error message:
Execute failed: org.apache.poi.openxml4j.exceptions.InvalidOperationException: A part with the name '/xl/drawings/drawing5.xml' already exists : Packages shall not contain equivalent part names and package implementers shall neither create nor recognize packages with equivalent part names. [M1.12]
This is the error message when i execute it from the server:
ERROR XLS Sheet Appender 1:412 Execute failed: ("ArrayIndexOutOfBoundsException"): null
Is this a bug or am i doing something wrong?
