Hi there, When I want to change category of an issue I get internal error. The log is the following:

ActionView::Template::Error (undefined method render_issue_category_with_tree_inline' for #<#<Class:0x007f61ec1c6bf0>:0x007f61eec3cf38>): 1: <%= "(#{l(:field_private_notes)}) " if @journal.private_notes? -%><%= l(:text_issue_updated, :id => "##{@issue.id}", :author => @journal.user) %> 2: 3: <% details_to_strings(@journal_details, true).each do |string| -%> 4: <%= string %> 5: <% end -%> 6: app/helpers/issues_helper.rb:307:inshow_detail' app/helpers/issues_helper.rb:277:in block in details_to_strings' app/helpers/issues_helper.rb:263:ineach' app/helpers/issues_helper.rb:263:in details_to_strings' app/views/mailer/issue_edit.text.erb:3:in_app_views_mailer_issue_edit_text_erb___3153075802587236381_70029275035580' app/models/mailer.rb:411:in block in mail' app/models/mailer.rb:410:inmail' app/models/mailer.rb:74:in issue_edit' app/models/mailer.rb:423:ininitialize' app/models/mailer.rb:446:in method_missing' app/models/mailer.rb:86:inblock (2 levels) in deliver_issue_edit' app/models/issue.rb:831:in each_notification' app/models/mailer.rb:85:inblock in deliver_issue_edit' app/models/journal.rb:77:in block in each_notification' app/models/journal.rb:75:ineach' app/models/journal.rb:75:in each_notification' app/models/mailer.rb:84:indeliver_issue_edit' app/models/journal.rb:190:in send_notification' app/models/journal.rb:54:insave' app/models/issue.rb:1520:in create_journal' app/models/issue.rb:165:increate_or_update' app/controllers/issues_controller.rb:478:in block in save_issue_with_child_records' app/controllers/issues_controller.rb:466:insave_issue_with_child_records' app/controllers/issues_controller.rb:188:in `update'
