Hello, I have recently been developing a standalone oXygen 12.0 workspace plugin that produces an XML document containing oXygen's track-change processing instructions. Currently this plugin can write its results either to an existing editor or to a file. In the latter case the file is opened in an oXygen editor once it has been written. In the former case, the editor is correctly updated but not selected as the current editor. Is there a way of selecting this output editor as the current editor from within the plugin? I would also like to allow the user to send the output to a "new" freshly constructed editor window with an appropriate "untitled #number" name, where the action of "saving" the document would prompt the user for the location to save the file in. There may be cases where the user just wants to view the result, rather than save it to a file. We generally know the type of document that is being generated (e.g. DITA, DocBook, general XML) so could supply this to the oXygen editor creation API, if this is helpful. Any pointers on how this - or something similar - could be achieved would be welcome. I am new to the oXygen plugin development and this mailing list; and have done my best to search both the API and archive for answers to the issues I have just raised. I apologise in advance for missing previous answers to these questions. Regards, Anthony.
