[Mapbender-dev] Spatial request: WFS / WMS relation

[Christoph Baudson]

Quite recently we were having a bit of trouble configuring a WMS in 
order to work with a WFS. I opened the following ticket

http://trac.osgeo.org/mapbender/ticket/330

In a nutshell:

Up to now, the layer that is linked to the WFS configuration would have 
had to be both visible and a querylayer (that is, queryable and 
activated for querying). The reason was, that in certain scenarios, you 
might only want to retrieve objects of a certain theme. Just imagine a 
rich application with lots of different WMS / WMS relations. A spatial 
request would produce endless results.

However, the querylayer attribute is by definition an attribute to 
control a WMS feature info request. So coupling this with a WFS looks 
now a little "forced" and misplaced.

My proposal is to remove the querylayer condition from the "if" 
mentioned in the ticket. You could still deactivate the spatial request 
by setting the layer to "not visible". So the only thing we would lose 
in such a solution would be this: You were unable to exclude layers from 
spatial request while having them visible at the same time.

Would this be a major change? Could this be part of 2.5.1 or would we 
have to defer this to 2.6? Do I make any sense?

Let's discuss,

Christoph
