Redmine

Sorry, I don't understand the question !

I try to copy a project inside another project
ok ?
And Redmine copy the project, but not within the project you specified, Redmine copy the project in root.

If I change the line 122 in the file /app/controllers/projects_controller.rb
From
if validate_parent_id && @project.copy(@source_project, :only => params[:only])
to
if validate_parent_id && !@project.copy(@source_project, :only => params[:only])

This function works but I dont know if this is correct.

I already know what the problem Redmine project does not copy correctly to the desired directory if it has any issue.

Also do not copy the issues

Redmine not copy the issues because I added a custom field in the issues (after) and this is also required

Is it the same as #5826 ?

I presume issues are not supposed to be copied with the project, you are free to do that afterwards from the issue list.

That was the problem, I put a value in this field and working properly the copy, sorry and thanks
