Hi All. I'm new to the list and have some newbie questions related to editing some data using GeoExt/OL/Geoserver/posgres/postgis. If this is not the best place to ask, please let me know where is.
I have made a good start to a little utility to visualize and edit some data but have a few problems I could use help with and it may be a general problem with the approach I am taking. I have two sets of data, one being start and end points defining some road segments, and the other being road links (this is navteq street data). I have a vector layer for the points using a multipoint geometry from postgis (maybe my first problem) and another vector layer for the street lines with a filter applied, and stores for each. The point data is bound to a GridPanel and a map, and the line data is bound to another GridPanel as well as the map. The point data grid is populated on startup and when the user selects a row, the filter is applied to the line layer and refreshed, and the line grid gets populated as well as zooming the map to the extent covered. Using a DrawFeature control I have been able to edit my points and save them back to the database. So the 2 main problems I have are right now are 1. How can I treat these two points differently in terms of styling? I would like to style the start point differently from the end point so you can tell which is which. I put them in a multipoint because I didn't see how to handle individual lat/lon pairs (which I have) or have multiple geometries per row/feature. 2. How can I differentiate between selecting a feature in a grid, versus on the map using a FeatureSelectionModel? When I select a row in the grid I want to zoom to the extent covered by the two points, but not when I click on one of the points on the map because if say I am zoomed in, it zooms me back out . It appears to reload the line layer every time I select one of the points as well (even if that layer is loaded) which seems overly aggressive. So I guess I am wondering if I can get better automatic binding without doing it all myself. I don't have this visible publicly yet, but let me know if I need to provide more info to get help.
