Ah,
thanks Jonathan. Well, i copied those warnings aswell from the thread.
My warning is only 7, which is CAMERA_MATRIX. So good to know what the
value means, this sheds some light.
It's obvious, i think i'm getting old and tired :)
Works now!
Thank you,
Thomas

Well, the warning is pretty self explanatory - though you need to look
at MatrixArray.h to figure out what the indices mean.
More than likely the Scene containing the lights hasn't had its
evaluate_lights() method called to get all the matrices up to date -
this is normally done automatically by the Render class. It can be
expensive to call so it's not done automatically in validate() - it's
only done if the Render subclass is actually going to start rendering.
Your calculations are correct because the individual matrices in the
array are initialized to the identity, but their valid flag is false
which means they've never been explicitly set (look at the
MatrixArray::MatrixEntry structure.).
So from the indices listed it appears neither the CAMERA_MATRIX,
PROJECTION_MATRIX, or the FORMAT_MATRIX have been set, which means
only the OBJECT_MATRIX has been.
So if you did anything like transform a point into the light's UV
space using the MatrixArray's transform methods the result would be
completely incorrect unless the object matrix contained the complete
transform - thus the warning.

Sorry,
i was writing on the forum and it didn't bring the original message
along in the mailing list (From Feb 15, 2011 by Moritz Moeller). i am
refering to this thread here, which remained open:

When working with lights and transforms, get errors like these:
MatrixArray::matrix(13) - Warning, matrix is unassigned
MatrixArray::matrix(19) - Warning, matrix is unassigned
MatrixArray::matrix(7) - Warning, matrix is unassigned
MatrixArray::matrix(13) - Warning, matrix is unassigned
MatrixArray::matrix(19) - Warning, matrix is unassigned
MatrixArray::matrix(7) - Warning, matrix is unassigned
Though, everything i'm calculating seems to be correct....
