Issue with parameterized metadata file

There's an issue with CloverGUI while using parameterized metadata file.

Indeed in a graph I want to use:

<Metadata fileURL="${metadata}" id="Metadata0"/> /* ${metadata} is a path to a .fmt file */

instead of (for example):

<Metadata fileURL="c:\table.fmt" id="Metadata0"/>

It generates an error in Eclipse :
ENGINE: Error during graph initialization (Can't parse metadata: Metadata0).

Could you fix this problem in the next release please ?

Thanks a lot.

  Hi,
  this should work. Which version of GUI and engine are you using? Are you sure that the metadata file is valid? The comment for the metadata parameter ("/* ... */) is not in the graph XML file, I suppose? You could post the graph and the metadata file here.

  The graph file is the same as with the problem of slowdown with CloverETL Engine 2.2 :-)

  I don't understand. My metadata file is dynamic. I think that it's just that CloverGUI generates an error while parsing a graph file within the fileURL property of metadata node is not a real path but à property like "${xxxx}".

  Pls, check if you set correctly path name ( "c:\table\customer.fmt" is interpreted as "c: able\customer.fmt", for "c:\table\customer.fmt" you should have "c:\\table\customer.fmt).

  I may add something about this problem :
  
  The problem only appears while opening a graph file in the java or other perspective under Eclipse.
  
  Of course under CloverGUI perspective there are no issue.
  
  Try to make a graph and then edit with a text editor the metadata node as below :
  
  <Metadata fileURL="${file_url}" id="Metadata0"/>
  
  Then you'll have an error in the problem view of Eclipse :
  ENGINE: Error during graph initialization (Can't parse metadata: Metadata0).
  
  There will be also a "white cross over red background" icon over the graph file in the package view of java perspective.
  
  See you.

  Hello,
  I can't recreate this issue. Pls check what is written as reason (on the end of log should be something like that:
  Caused by: java.io.IOException: Can't read metadata definition file: metadata\delimited\employeeDB.fmt (No such file or directory)
  at org.jetel.metadata.MetadataFactory.fromFile(MetadataFactory.java:62)
  at org.jetel.graph.TransformationGraphXMLReaderWriter.instantiateMetadata(TransformationGraphXMLReaderWriter.java:312)
  )

  I think that nobody understand me. My issue is not while I execute a process.
  It's just a display issue under Eclipse.
  
  Below is a picture of what I have under Eclipse :

  When I execute a graph it works great. The ${metadata} can be any path.
  I repeat it's just a display issue under Eclipse in other perspective than Clover.ETL one.
  
  It may help everyboby.
  
  Thanks.
