  2.  Share the project with a component.
  3.  Right click on the component and select Show Repository
  files, try opening the *.rex file.
  
  Workaround:
  NA
  

Local fix

• NA
  

Problem summary

• Opening a file from the EWM "Repository Files" view creates
  editor input which does not exist in an Eclipse project on the
  local file system, causing file existence checks to fail when
  the text editor consumes the input.
  

Problem conclusion

• Temporary files need to be created in an Eclipse project for
  each EWM "Repository Files" view file opened. That temporary
  file can be properly consumed by the text editor.
  

Temporary fix
