I produced a template having 2 page styles (preface page style and default page style-tailored).
Then started 2 subdocuments based on the template. One is the preface, using the preface page style and the other is the chapter one using the default page style-tailored. Both look satisfactorily.
Then I produced the master document, also based on the template. Included are, by order, the preface subdocument and then the chapter one subdocument.
In the master document appears text of the preface suddocument using the preface page style, AND then text of the chapter one sudocument BUT USING the preface page style (instead of the default page style-tailored).
If, in the master document, I change the page style of the pages of the text belonging to the chapter one subdocument to the correct default page style-tailored, the effect is that such change is also affecting to the text of the preface subdocument!
And again, any change in page style is affecting all text of both subdocuments.
Any ideas how to solve? Thanks in advance.
