EditBox: cursorOffset and cursoHeight

I got some strange errors in the beta concerning new properties of the EditBox:
cursorOffset and cursorHeight.

It seems the Blizzard OnLoad code does not set two new properties properly.
At least I got nil errors because they were not set.

Does anybody have an information about that?

Original code (getting nil errors with it):

Code:

              <EditBox name="$parentEdit" enableMouse="true" multiLine="true" AutoFocus="false">

                <Size>

                  <AbsDimension x="264" y="281" />

                </Size>

                <Scripts>

                    <OnUpdate>

                        ScrollingEdit_OnUpdate(self,0);

                    </OnUpdate>

                    <OnTextChanged>

                        ScrollingEdit_OnTextChanged(self);

                    </OnTextChanged>

New code (working):

Code:

              <EditBox name="$parentEdit" enableMouse="true" multiLine="true" AutoFocus="false">

                <Size>

                  <AbsDimension x="264" y="281" />

                </Size>

                <Scripts>

                    <OnUpdate>

                        self.cursorOffset = self.cursorOffset or 0;

                        self.cursorHeight = self.cursorHeight or 0;

                        ScrollingEdit_OnUpdate(self,0);

                    </OnUpdate>

                    <OnTextChanged>

                        self.cursorOffset = self.cursorOffset or 0;

                        self.cursorHeight = self.cursorHeight or 0;

                        ScrollingEdit_OnTextChanged(self);

                    </OnTextChanged>

Assuming you have the ScrollFrame/ScrollChild hierarchy correct, shouldn't it look more like:

Code:

        <EditBox name="$parentEdit" enableMouse="true" multiLine="true" autoFocus="false">

                <Size x="264" y="281"/>

                <Scripts>

                        <OnCursorChanged function="ScrollingEdit_OnCursorChanged"/>

                        <OnTextChanged>

                                ScrollingEdit_OnTextChanged(self, self:GetParent())

                        </OnTextChanged>

                        <OnUpdate>

                                ScrollingEdit_OnUpdate(self, elapsed, self:GetParent())

                        </OnUpdate>

No.
If self.parent is not supplied, then blizzard is adding it for itself. I looked at the code, believe me.
This has nothing to do with my findings.

Even with your code I get the same error:

Code:

Message: Interface\FrameXML\UIPanelTemplates.lua:379: attempt to perform arithmetic on field 'cursorOffset' (a nil value)

Time: 09/16/10 00:55:04

Stack: Interface\FrameXML\UIPanelTemplates.lua:379: in function `ScrollingEdit_OnUpdate'

Well the functions ScrollingEdit_OnCursorChanged, ScrollingEdit_OnTextChanged, and ScrollingEdit_OnUpdate are the same on live and beta. That leaves the parenting of your ScrollFrame/EditBox in question (since it is not shown) or you are overlooking the ScrollingEdit_OnCursorChanged difference between what I posted and what you posted (since that is where cursorOffset and cursorHeight are set).

Hm, I was detecting this while updating my addon for cataclysm.

The parenting is ok.

But perhaps in cataclysm, for locales other then deDE, ScrollingEdit_OnTextChanged is called before ScrollingEdit_OnCursorChanged.
That would explain the differences I see.
