[mapserver-dev] mapswf.c : mappostgis.c complains that the layer is closed

[Laurent BAEY]

Hello

I upgraded from 5.2 to 5.6.6.

When drawing the labels with the SWF-MULTIPLE driver, I get the error :
httpd2-prefork: mappostgis.c:1882: msPostGISLayerResultsGetShape:
Assertion `layer->layerinfo != ((void *)0)' failed.

If I get it right, we're trying to get info from Postgis, but the layer is
closed.
Therefore, msPostGISLayerResultGetShape complains that layer->layerinfo is
null.

It happens when the msDrawStartShapeUsingIdxSWF function is called in
msDrawLabelCacheSWF.

By adding a msDebug call, I can confirm in the ms_error log the layer is
closed :

[Tue Feb 15 19:01:04 2011].858442 calling msDrawStartShapeUsingIdxSWF
(bLayerOpen = 0)

Is there another problem I didn't catch ?
Has something changed since mapserver 5.2 concerning postgis layer
manipulation, but hasn't been commited in mapswf.c for labelcache drawing ?

Thank you for help
