Hi everybody,
I am trying to implement the following behaviour:
1.A combo list is displayed showing a set of wfs layers
2.The user selects one of the layers from the list
3.A new form is displayed below with input text fields only applicable for the
selected layer (each layer has a different set of fields)
4.The user enters values inside the new form to send filter requests to
geoserver
5.The main MapPane is refreshed with the results from the filter request
With the help of some posts of the forum and the contextEditor and
gazetteerTools demos, I have the combo (steps 1 and 2) and the filters (steps 4
and 5) working separately. The problem comes when trying to connect the 2nd and
3d steps. I need to avoid having a static xml filter file for each layer.
I was thinking about launching a DescribeFeatureType request from the layer
selection, and create another widget that handles the DescribeFeatureType
output and generates the desired xml (with a xsl). But I'm not sure if this
sort of handling is possible, and even if it was, I don't know if the xml
obtained can be passed somehow to a widget similar to the PlaceNameForm widget
from the gazetteer demo (the filter xml file is generated on the fly, so I
suppose that I cannot use the defaultModelUrl).
Do you have some ideas about the best way to proceed?.
Thanks,
Héctor.
