Redmine

When I export CSV file from Issues.
Now the filter for issues, e.g. status, categories are not applied and all opened issues in the project are exported.

I was confirmed that this problem only occurs in version 3.2, not in 3.1.

I found 2 points.

1. CSV export options form doesn't send proper parameter.
\app\views\issues\index.html.erb line 80
form_tag(params.merge({:format => 'csv',:page=>nil}) a form tag with parameters in the action attribute.
But, parameters don't send to the controller.(This has occurred even 2.6.)
And so, IssuesController#index tries to get the filter from session data.

2. Format of session data changed in 3.2
queries_helper.rb line 215

session[:query][:project_id] != (@project ? @project.id : nil)

session[:query][:project_id] is nil.
session[:query]["project_id"] has the project_id.

And so, IssuesController#index cannot get the filter from session data.
