hi, I'm sure this is a duplicate.. sorry... but I think I can put it very clearly which may help solving this issue... When you create a template you do it like: "File / Templates / Save as template" The result of this is that the new template will be based off of the template which the document was based on (from which the template was made) This is bad. I mean: from temp-1 --> doc-1 from doc-1 --> temp-new temp-new is linked to temp-1 This really is bad. Templates should be style sheets, determining the look and layout of documents... not the other way around. But in any case, templates should never update because another template was modified. SOLUTION: When a new template is being generated, linking to the template which the document (from which the template was generated) was based on SHOULD BE CLEARED. Why? Cause no template should update when a template is being modified.
PS: As you know, linking to a template in a document is handled in meta.xml You clear it there and that's it.
Every document is based on a templates, and you can save any document as a template. There is no chain relation. https://books.libreoffice.org/en/WG71/WG7110-WorkingWithTemplates.html
