[Mapserver-dev] Problems with itemquery in version 4.0

[Jordi Valls]

Hello mapserver users,

I am trying to use the itemquery example, from the test suit, with the
version 4.0.
I am using the mode itemquery and the parameters set with qitem and qstring.
The template displays correctly the values of the atributes of the feature
selected, but the map gets to nothing. Mapserver generates an image that
contains nothing. The template I use in the layer is :

<table cellpadding="5">
<tr>
<td>
<b>Nom:</b> [NOMM]<br>
<b>ID Numero:</b> [CODI]<br>
<b>Comarca:</b> [NOMC]<br>
</td><tr>
<td>
<img border="2" src="[img]" height="550" width="750"></td>
<td>
<img border="2"
src="http://pc12975[program]?map=[map]&qstring=[qstring]&qitem=[qitem]&mode=
itemquery&mapext=shapes&qlayer=[qlayer]" height="550" width="750">
</td>
</tr>
</table>

but [img] is correctly set to a jpg file that contains nothing and the
second image also displays nothing . Is this a bug of mapserver 4.0 or I am
doing something wrong?.Does anyone have an example of itemquery that runs on
version 4.0?

The first template:

function startquery()  {
      var i;
    document.mapserv.qitem.value="CODI";
    document.mapserv.qlayer.value="Municipis";
    document.mapserv.mode.value="itemquery";
      for(i=0; i<document.mapserv.codi.length; i++) {
        if(document.mapserv.codi.options[i].selected){
    			document.mapserv.qstring.value=municipisIne[i];
					}
      }
	  document.mapserv.submit();
}
.....
<td width="10">
<select name="codi" size="1" style="width=155">
<script language="JavaScript">write_municipis()</script>
</select>

and an abstract of the map file:

LAYER   NAME "Municipis"
  DATA MunicipisCD
  TYPE POLYGON
  STATUS OFF
  LABELITEM "NOMM"
  TEMPLATE demo_item.html
  CLASS
	 NAME "MUNICIPIS"
	 COLOR -1 -1 -1
	 OUTLINECOLOR  255 0 0
     LABEL
	    COLOR 0 0 0
	    SHADOWCOLOR 218 218 218
	    SHADOWSIZE 2 2
	    TYPE BITMAP
	    POSITION CC
	    PARTIALS FALSE
	    BUFFER 2
     END # end of label
  END
END # end of  layer

Many Thanks,
