Mesh disappear after adding ipo-animation

hello,
my cube disapper after i added an ipo-curve to it.
but when i start the animation the cube is visible again. so how can i make the cube visible without starting the animation?

Can you do a bit of debugging and check where the render function of that object jump? That will help me to check where it can be wrong...

I had the same problem. The reason for me was in sio2ObjectRender: the IPO's matrix is applied even if the animation is not set to play, but this matrix contains random values initially and is only filled with valid ones in sio2ResourceRender if the IPO has been set to play. I worked around this in the method sio2ObjectRender of file sio2_object.cc by replacing the line

if( _SIO2object->_SIO2ipo)

with

if( _SIO2object->_SIO2ipo && _SIO2object->_SIO2ipo->state == SIO2_PLAY)
