ISO 286/14405-1 calls for a plus sign if the limit is positive and a
minus sign if the limit is negative. A zero limit should have neither
a plus nor a minus sign. This commit adds the plus sign.
- this is a temporary measure to prevent problems caused by a
bad value for LineStandard parameter. A previous devel version
stored on invalid value. This patch can be removed before
moving to production.
- this condition can be corrected by editing LineStandard to 0, 1 or
2. a plethora of warning messages is issued until the parameter is
corrected.
This fixes a regression of PR #11266 that dropped the case where neither the option 'Ignore project unit system and use the default' is set
nor an active document exists. In this case nothing happens even if the user changed the unit system.
The proposed code fixes the following issues:
1. There is no check if the target object itself has a property that matches the label type.
2. If a subelement is selected that does not have the label type property, the value from the main object is displayed instead.
3. The default text is an empty string.
Example:
Currently If you select a vertex of a wire, and select "Length" as the label type, you will get the length of the wire. With the new code the text will then be "Length not available for (sub)object".

The reason of the crash is a static_cast of an unknown type that causes undefined behaviour. The feature AdditiveLoft has the
property Section of type PropertyLinkSubList but the function does a static_cast to PropertyLinkList.
The solution is to use a dynamic_cast that returns null if the cast fails.
* fix hard crash in MainWindow::_updateActions() if no MDI view exists
* in MDIView::buildWindowTitle() use the label of the document because this changes when saving it while the name is immutable
* fix const correctness in MDIView::buildWindowTitle()
* do not set the modified flag of the main window in MDIView::buildWindowTitle() but in the calling instance
* move setting the main window title to Application::viewActivated to reduce code duplication
* fix missing application name if FreeCADGui is loaded as Python module
