TypeError: Error #2007:

Question

I am getting this runtime error-

TypeError: Error #2007: パラメーター text は null 以外でなければなりません。

Parameters text is must be non-null at flash.text::TextField/set text() at Tile/refresh()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Tile.as:68] at Tile/init()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Tile.as:58] at flash.display::DisplayObjectContainer/addChild() at Main/tileform()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Main.as:115] at Main/deal()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Main.as:106] at Main/createtile()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Main.as:86] at Main/init()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Main.as:54] at Main()[C:\Users\Makiko\Desktop\Michael\Games\New Project\src\Main.as:33]

I can't quite an exact equivalent question.

I think this code is the source of the issue but how to fix it?

Answer 1

Error 2007 will occur when trying to set a property to a null value when it requires a non-null value. I believe kanalocal is the null value.

myText.text = kanalocal;
