@acmbear @catbill : a template is recorded in the properties only when the document was created File
>New
>Templates
.
Double-clicking on a template icon in the file browser immediately creates a standard document from the template (styles + initial contents). The Writer Guide is correct.
@ElSid : there is no provision for template chaining and it is probably a good thing because you could create circular references.
I understand your problem and support your desire. Presently, the only workaround I think of is a 2-tier procedure. Create your secondary templates as ordinary documents and store them in one of your directories. When a change is made in the primary template, open the secondary documents to update them (but be aware that only styles are updates, not any contents like logos, phone numbers, addresses, though you can put the latter in properties and insert them through fields). Save the modified documents then File
>Template
>Save as Template
to incorporate them to the template library.
Take special care that Writer doesn’t delete the document backup of your templates. This may need to use File
>Save a Copy
.
