Redmine

Hi everyone,
we recently migrated to redmine 4.2.3 and encountered an error with Tickets having subtasks.

We got the following error (ending up in http 500 error):

Unknown column 'issues.is_closed' in 'order clause': SELECT COUNT(`issues`.`id`) AS count_id, `is_closed` AS is_closed FROM `issues` INNER JOIN `projects` ON `projects`.`id` = `issues`.`project_id` INNER JOIN `issue_statuses` ON `issue_statuses`.`id` = `issues`.`status_id` WHERE `issues`.`root_id` = 28341 AND (issues.lft > 125 AND issues.rgt < 150) AND (projects.status <> 9 AND EXISTS (SELECT 1 AS one FROM enabled_modules em WHERE em.project_id = projects.id AND em.name='issue_tracking')) GROUP BY `is_closed` ORDER BY `issues`.`is_closed` ASC):
    110: </div>
    111: <p>
    112:   <strong><%=l(:label_subtask_plural)%></strong>
    113:   <%= render_descendants_stats(@issue) unless @issue.leaf? %>
    114: </p>
    115: <%= form_tag({}, :data => {:cm_url => issues_context_menu_path}) do %>
    116: <%= render_descendants_tree(@issue) unless @issue.leaf? %>

app/helpers/issues_helper.rb:149:in `render_descendants_stats'
app/views/issues/show.html.erb:113:in `_3816cc2767ebce33b1776af4cb28388a'
app/controllers/issues_controller.rb:112:in `block (2 levels) in show'
app/controllers/issues_controller.rb:104:in `show'
lib/redmine/sudo_mode.rb:61:in `sudo_mode'

The mysql Statement seems to be wrong at the ORDER BY Statement:
... GROUP BY `is_closed` ORDER BY `issues`.`is_closed` ASC)
'issues'.'is_closed should be 'is_closed'.

Currently we "implemented" a workaround by removing the reorder statement on app/helpers/issues_helper.rb:149
before:

    subtasks_grouped = issue.descendants.visible.joins(:status).select(:is_closed, :id).group(:is_closed).reorder(:is_closed).count(:id)

after:

    subtasks_grouped = issue.descendants.visible.joins(:status).select(:is_closed, :id).group(:is_closed).count(:id)

At least here are our system specs:
