** Hi, I tried using the FormPanel but the QueryPanel seems to fit better in this case. I want the user to be able to filter data coming from a WFS after specifying certain conditions, which differ from case to case.
I got the GeoExt QueryPanel working so far, it recognizes the layers available on my Geoserver but it is not able to get the attribute columns of the dataset. I configured a proxy on my Apache Server. A DescribeFeatureType request is sent when selecting the layer I want to filter from. The same happens when trying to choose the attribute column in the query panel, but there are none displayed. These are the request URLs: [ http://localhost/cgi-bin/proxy.cgi/wfs?VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=cases] [ http://localhost/cgi-bin/proxy.cgi/wfs?VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=cases&query=] Opening the reply bodies of these requests in a new tab via Firebug, I get to the OpenLayers webpage... Does anybody have a clue what´s going wrong here and why the attribute fields cannot be read but all the layers on geoserver are displayed? @ Matt: The print function is what I need for the Map "Export". Furthermore I want to be able to export the attribute table of the query made in the QueryPanel as a *.csv or similar filetype that can be read in Excel. Any help is appreciated!

With regards to exporting your map and grid, that really depends on what you are really trying to accomplish. Do you want an snapshot of the map or grid? Or Do you want to export the query and map extent so that the particular view can be recreated? If you want a snapshot, do you want to simply print the grid or map? Or do you want to actually export the data itself.

Hi all! I´m trying to build a webmapping application with GeoExt. What I want to do is to create a query panel in which I can define conditions which filter the data from a WFS. It should filter the data displayed in my map panel as well as my grid panel. Additionally, I want the user to be able to export query results as maps and tables. Anyone knows if that´s possible as well? Basically, I want to use the GeoExt QueryPanel ( http://workshops.opengeo.org/geoext/_images/attributes.png). Does any of you know how to create this or knows any nice tutorial? The OG workshop documents concerning WFS browsing, querying and SLD filtering<http://workshops.opengeo.org/geoext/more_ogc/app.html>( http://workshops.opengeo.org/geoext/more_ogc/app.html ) look promising but I can´t really follow it, since the source code does not work anymore / on my machine / somehow. Anyone with experience in this issue? It seems like a common element to develop I think... Too bad, good documentation is missing. It would be great to get help in this case, since the issue´s not heavily discussed on mailinglists or boards...
