Re: [udig-devel] PostGIS Views as Layers
|
OK I'll have to get our local Postgis guru to help me set up views so
I can test this. But I'll do what I can.

When do I get an IPhone? ;P

It is correct that a re-render does not show the new data in the
view, even though the new data is well within the bounding box. The
correct data is in the table view and it renders correctly after a
restate of udig, but after a refresh in the same session.

I'm not sure exactly what you want here. So you update one of the
tables that the view is constructed from. But when you trigger a
re-render it doesn't show the new data? Is that right.
Assuming so. Does it show new data if the data is well within the
existing bounding box?

I am using uDIG RC13 to visualize PostGIS layers under OSX. In
general, this has worked very well, but there is one last thing
that I need to make this a smashing success. I want uDIG to
respond to changes in the underlying PostGIS tables based on my
input. I do this using views as features as follows:
1. I create PostGIS tables with a "visible" column.
2. Based on an event, I have a trigger function manipulate the
"visible" column to mark only the records I want to show.
3. I create views of the tables in PostGIS to contain only those
records marked visible. The geometry column is registered for
these views.
4. I add the views as layers in uDIG. When I start uDIG, it
correctly displays the layers.
The problem occurs when I then trigger an event and the views
change in PostGIS. When I refresh the display in uDIG, the old
view disappears, but the new contents of the view do not display.
It's like there is not a refresh of the geometry from the
database. Ironically, the new attributes of the views display
correctly in the Table window. If I then close uDIG and open it
again, the correct view contents are pulled in and displayed.
