Custom Attribute Controls - issue with AttributeSave

[Alwarren 2767]

Hello.

 

In absence of an issue tracker, I'll post this here.

 

I am writing a custom attribute edit control. The Attribute entry looks like this:

class FHQ_MissionBriefing
{
    displayName = "Briefing";
    property = "FHQ_BriefingAttribute";
    control = "FHQ_BriefingEdit";
    expression = "if (!is3DEN) then {[_value] call FHQ_fnc_ttiMissionBriefing;}";
    defaultValue = "[]";
    value = 0;
};

 

The FHQ_BriefingEdit control starts like this:

 

class FHQ_BriefingEdit : TitleWide
{
    attributeLoad = "['attributeLoad', _this, _value] call FHQ_fnc_tteEditBriefing;";
    attributeSave = "['attributeSave', _this] call FHQ_fnc_tteEditBriefing;";
    onLoad = "['load', _this] call FHQ_fnc_tteEditBriefing;";

What I see, however, is that when I click the OK button, attributeSave is called twice. While this is normally not a problem (albeit being redundant), it can pose an issue if the attributeSave function has side effects.

 

Question: Is this intended behavior? Or a bug?

It's intentional. First run is for data validation, and second will actually apply them.

Added to the documentation.
