[maplab-users] Maplab frustration!

[Paul Spencer]

Matt,

The problem with the 'empty' legend causes the preview problem because
once you do anything that causes the page to submit, the code looks for
layers to turn on/off from the legend.  Since there is nothing there,
all the layers get turned off.

The code checks to see if a 'valid' legend template is set in the map
file and will use that in the mapedit preview if found.  Unfortunately,
the php code that checks to see if a file exists returns true if the
file name is "", and the code that shipped with RC5 and earlier relied
on this to return false.  This is fixed in the latest CVS version, but
you can work around it by specifying a value for TEMPLATE inside the
LEGEND object.  It may be that the TEMPLATE value has to end with
".html" (i.e. ttt.html)?

If this doesn't work, please send me your map file to try.

Thanks,

Paul
