Hi Dirk,

you are definitely right on this! How come nobody has stumbled over it until now???

Are you going to file a bug about this or shall I do so?

Kind regards

Markus

| Hi list,
|
| checking the 4.2.0 CGI mapserver, a ran across a weird template problem
| regarding the [layer], [layer_esc] and [toggle_layers] variables.
|
| The output with the same querystring of
|
| &map=/home/springm/perl/Geo-
| UMNmapserver/t/maps/verwaltungsgrenzenflur/verwaltungsgrenzenflur.dfo.map
| &mode=browse
| &layer=l1
| &layer=l0
| &layer=bgl15
| &layer=bgl11
| &layer=bgl20
| &zoomdir=1
| &zoomsize=2
| &mapsize=400+300
| &scale=9700
| &mapxy=4465711.0965965+5341175.7092885
|
| (of cours all in one line) returns:
|
| <!-- MapServer version 4.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
| SUPPORTS=FREETYPE INPUT=TIFF INPUT=JPEG INPUT=SHAPEFILE -->
|
| => layers:              l1 l0 bgl15 bgl11 bgl20
| => toggle_layers:       bgl99 bgl20 bgl11 bgl00 bgl00 bgl00 bgl00 l0 l1
| bgl98
| bgl15 bgl08 bgl08 bgl08 bgl08 bgl08 bgl08 MSSuser __embed__scalebar
| __embed__legend
|
| and
|
| <!-- MapServer version 4.2.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
| SUPPORTS=FREETYPE INPUT=TIFF INPUT=JPEG INPUT=SHAPEFILE -->
|
| => layers:              bgl20
| => toggle_layers:       __embed__legend
|
| I have no explanation for this behavior.
|
| Kind regards
