Michael Anstis created DROOLS-3048: -------------------------------------- Summary: [DMN Designer] CellEditorControl needs to issue a new instance per use Key: DROOLS-3048 URL: https://issues.jboss.org/browse/DROOLS-3048 Project: Drools Issue Type: Bug Components: DMN Editor Affects Versions: 7.12.0.Final Reporter: Michael Anstis Assignee: Michael Anstis Priority: Critical A {{Popover}} used to edit a cell or column header (or any other DOM-based editor for that matter) disappears following a change in the widget that causes a {{Layer.draw()}} if the grid is sufficiently wide that there is a column not visible on screen. All cells/columns that use {{CellEditorControls}} (containing, for example, the {{Popover}}) share a single instance from {{CellEditorControl}} and hence although the User makes a change in a visible column the invisible column (scrolled off screen) has its DOM resources destroyed that is the same instance as that for the visible column. See https://github.com/kiegroup/appformer/blob/master/uberfire-extensions/ube.... If a column is not in the _body_ or _floating_ columns collection its DOM resources are destroyed. I probably need to ensure different instances of {{CellEditorControl}} are created for each column/cell where we currently share the same instance. Also check for destruction of DOM elements in {{Document}} when grids/columns etc are destroyed. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
