When creating Mail Merge data via query from a registered Base database, Mail Merge Wizard does not merge the result set into the document.

To create this situation, one must define a query on a Base database where the database is registered in the Libreoffice environment.  Assuming that query exists, the following steps will demonstrate that Mail Merge does not populate a Writer document.

1. Open a template file (ott) or a new Writer document;

2. If the file is a template, skip to Step 4;

3. If a new document, create any constant information on the document.  For example, if you are merging names into a document that has name tag labels, you may want some constant data to appear such as a logo or organization name on all name tags;

4. Go to Insert>Field>More Fields>'Mail merge fields' and in the right window, choose your query name and expand it.  You will see the Field names assigned to the output of the query. Insert the first field that is to appear on the name tag;

5. Repeat Step 4 for as many fields as are to appear on the name tag;

6. Go to View>Toolbars> and click on Mail Merge to activate the Mail Merge toolbar;

7.  On the Mail Merge toolbar, click on the icon that is titled 'Data Source of Current Document'.  Two windows will open immediately below the Mail Merge toolbar;

8.  In the left hand window, click on the query name that you want to populate the document;

9.  The right window will now contain the query results.  Click on the upper left box beside the field names row to select all rows;

10. At this point, one can go through the Mail Merge Wizard, but it does nothing.  In fact you can go to Insert Address Block in the Mail Merge Wizard and choose the database to which the query belongs which doesn't change the outcome;

11. On the Mail Merge toolbar, click Saved Merged Documents.  You will see a counter that corresponds to the rows you have in your query result;

12. Another document will appear containing your original constant information and merge fields, but nothing has been merged.

The process described above should work, but does not.
