    Can not use XMLTools.loadXMLSchema() with modules-debug

    Hi,
    I am not able to debug sources using modules-debug because of exception in XMLTools.loadXMLSchema() method.
    Using standard setup:
    index.html
    Code:
    <!DOCTYPE html>

<html>
    <head>

        <meta http-equiv="content-type" content="text/html; charset=UTF-8">
        <meta http-equiv="pragma" content="no-cache">
        <meta name="gwt:property" content="locale=pl">
        
        <title>Client</title>
        
    </head>

    <body>

        <script type="text/javascript">
            var isomorphicDir = "./sc/";
        </script>

        <script src="sc/modules/ISC_Core.js">          </script>

        <script src="sc/modules/ISC_RichTextEditor.js"></script>
        <script src="sc/modules/ISC_Calendar.js">      </script>
        <script src="sc/modules/ISC_DataBinding.js">   </script>
     
        <script src="sc/skins/Graphite/load_skin.js"></script>

    index.gwt.xml

import com.smartgwt.client.util.SC;

public class MainEntryPoint implements EntryPoint {
   
    public void onModuleLoad() {

        XMLTools.loadXMLSchema("menuDS.xsd", new XSDLoadCallback() {

            public void execute(SchemaSet schemaSet) {
                SC.logEcho(schemaSet.getJsObj());
            }
        });
    }
   
}

    As far as the immediate error you're getting about inability to use error.stack, this was reported by another user, and we applied a fix that seems to correct the issue for that user, even though we weren't able to reproduce it ourselves. So you should update to the latest patched build; that may fix the entire problem, or just allow you to see the actual issue.

      Using latest build: SmartClient Version: v11.0p_2016-08-11/LGPL Development Only (built 2016-08-11)

          The underlying error was due to a naming problem with the schema files. It's been addressed in SGWT 5.1p LGPL and newer branches, and should be in the nightly builds dated 2016-08-22 and beyond.

          The separate chrome-specific error-reporting problem (which affected all SGWT variants) should also have been resolved in the same nightly builds.

            It is fixed for me (checked against SmartClient Version: v11.0p_2016-08-22/LGPL Development Only (built 2016-08-22)).
            Many thanks - it was troubling me for long.
