<DIV><FONT size=2>Hi</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>after the map modification, you could try
$msMapObj->save('/tmp/exportmap.map'); and see if the modifications you
have done are correctly outputed and look ok.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Even if the layer doesnt appear in the layer tree, it should
be displayed on map.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>
<DIV><FONT size=2>I noticed the layer type may not be set correctly by
mapoverlay, try doing it with mapscript (see below)</FONT></DIV></FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I just had a try with inserting a non-existing postgis layer
into a mapfile using mapoverlay ( and a bit of mapscript because some
properties are not supported by mapoverlay) and my layer was displayed
correctly on map.</FONT></DIV>

is having a set of empty layers in the mapfile (and also in the layers.ini),

[Cartoweb-users] Problem creating new layers</DIV>
<DIV><BR></DIV>
<DIV dir=ltr>Hi all!<BR><BR>I'm using the 'mapOverlay' plugin in
order to modify the layers of my project. It has worked well to
modify existing layers, but when I try to insert a new one, it
simply does nothing.<BR><BR>Perhaps it is related to another problem
I'm facing: I can only hide a layer with "FilterProvider". If I try
to make visible a layer that is not set as visible by default in the
"layers.ini" file, nothing happens...<BR><BR>I hope someone could
help!<BR>Thanks in advance!<BR clear=all><BR>-- <BR>Nicolás Eugenio
