    Description

      When running BPM Suite on Windows and setting storesvgonsave to true the SVG is only generated at first time, when you edit and save the process the SVG will not be updated and the following exception will be printed in the logs:

       org.jbpm.designer.web.server.TransformerServlet.storeInRepository class org.uberfire.java.nio.file.FileAlreadyExistsException myprocess-svg.svg
org.uberfire.java.nio.file.FileAlreadyExistsException

      When debugging the issue we noticed that it tries to delete a file using a bad slash (slash for Windows systems), see:

      INFO [http-nio-8080-exec-2] org.apache.catalina.core.StandardWrapperValve.invoke DEBUG deleting asset in path: /MyProject/src/main/resources/org/myapp\myprocess-svg.svg

      Notice the last slash is changed. The reason why it happens is because TransformerServlet uses File.separator to merge the path to the SVG, but paths in repository seems to use linux slash.

          Bug - A problem that impairs or prevents the functions of the product. JBPM-7425 Error is displayed after process model SVG is updated

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Bug - A problem that impairs or prevents the functions of the product. RHBPMS-5187 Process model SVG is not updated in Windows environments

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
