Strange behaviour adding vector layer to Mapnik base layer

[Manel]

Hi,

I've detected a strange behaviour adding a vector layer (EPSG:4326) to
a Mapnik base layer. The same layer is not always properly rendered.

See the code below:

layout="absolute"

After loading the application the initMap() function is executed and
the layer is rendered OK.

If the application creation complete event is deleted and the
initMap() function is called using the button then the layer is
rendered in a wrong place.

Any idea why this happen? I'm doing something wrong?

Thanks in advance.
