[great-users] Exception: Metalocator could not be resolved

It sounds strange that it cannot work after you change the src or dst file in GREngine dialog. The exception says that the XSD/DTD file could not be found for the XML file. Would you send me your transformation file in exported XML file or I can take a look on your machine tomorrow.

	I have a GReAT transformation from a MetaGME metamodel called PICML to 
	an xml file defined by an UML model called cadena_scenario (interpreted 
	by UMT and then udm.exe). It currently works and gives no error. 

	BUT, if I try to change the source or the destination file for the 
	transformation into the GR-engine dialog, even if I select a new file 
	which is identical to the one currently used (and even if I re-select 
	the SAME file...), then it gives me this error: 

	<< Exception: Metalocator could not be resolved: cadena_scenario. Make 
	sure that it's a valid FILE either in the current directory, or in PATH, 
	or it's a valid URI, and it identifies a valid DTD. >> 

	Anyone knows what can be the reason? 

	I do have a file called cadena_scenario.xsd and its relative path is 
	written into the FileType->DTDPathname 

	In facts in the past the cadena_scenario was called cadena-scenario, but 
	it has been a while now that I'm using the new name. I have tried to 
	re-UMT-interpret the cadena_scenario model and then re-run udm.... the 
	problem stays. 

	Thanks in advance
