Hi, I'm currently integrating "exporting relational schema" functionalities into the designer. And in "Operations > Edit or export relational schema", I have moved the "exporting files" functionality in to a popup dialog box in the designer. So the process is working through ajax calls. But my problem is, although the header parameters are set correctly, downloading is not working. 'Content-Description: File Transfer' 'Content-Disposition: attachment; filename='myfile.pdf' 'Content-Type: application/pdf' Should I get the file as JSON encoded and the process it at the browser or, have I missed something? -- I'm using the function calls initialized from the schema_export.php with minor changes. cheers, Bimal.
