Labels in two renderings of the same map ?

[Lars V. Nielsen (GisPro)]

I've been asked to generate a map with an insert, i.e. adding a small area with a larger scale in the corner of the map.

I've accomplished it by performing two renderings of the same map, the second rendering after setting a smaller width/height and a
fixed extent, and using GD2 to merge the two images appropriately. This works perfectly.

However, I've sofar been unable to get labels to display in the small insert image. They show up perfectly in the main/large image.

I don't turn any layers on/off between the two renderings, and I don't have any label min/max scale settings in place for this
labelling layer (which btw. is an OVF layer).

I suspect that it's an issue connected with the label cache. I've tried to add LABELCACHE OFF to the labelling layer and remove the
commands $map->drawLabelCache() from my code, but it makes no difference at all: the labels only (and always!) appear in the main
window.

If anyone has come up with a way to control labels in two map renderings, I'll be delighted to know.
