well, there are frameworks like GeoExt that might already have offered this type of functionality. Did you ever try them? > Armin, do you have any plans about it?

It was not always easy to understand the sometimes strange logic of OL, and the OL mailing list was of no help for very specific questions (I practically never got any reply). So I was sometimes close to abandon the idea of using OL. Now I found most ways for workarounds, and the map navigation and interaction tools are mainly working. I'm currently in the final stage of rewriting the old and badly structured query code of p.mapper, this might be even possible to port it back to the p.mapper 4 (the new one will be version 5). The query stuff is again a bit of a mess, this time from the side of MapServer. But the new query classes should allow more easily to write you own functionality for the query result display if needed since this is now decoupled from actually getting the query result. A missing part is also the printing where I will mainly have to investigate how to print tiled layers that are not available via Mapserver (like OSM layers, Google layers will anyway not be allowed to be included in printings). Just to give an idea how the composition of layers from mapserver and OL works: You can define as now to have all MS layers (or groups) being rendered on a single map image, with or without tiling. Or you can split groups of layers into a few blocks, each block is an OL layer (I call the OL layers 'olThemes' to avoid too much of naming confusion). The combination which layers are rendered together or separately can be done in any type of combination. Using tiled layers for the time being will require to use the Google spherical mercator projection for the map. I cerated 2 new types of new OL layers, one tiled and the other non-tiled. Both are based on MapScript and will only work inside a user PHP session. It will be very likely that the first release version of p.mapper 5 will have some very specific functionalities not yet included, and most likely also only a few plugins will work already then. When the code is a bit more stable I will put it on the SVN, depending also if anyone is interested in contributing some developments. I might put a preliminary beta version out in the next week or so, so that people can have a look at it on their own installation. A first draft version (already 2 weeks old) is available at http://www.pmapper.net/demo/pmapper-5-dev/ http://www.pmapper.net/demo/pmapper-5-dev/?config=singletile some new functions beyond OL integrations already implemented are: - hierarchical level above categories (called 'domains') - more flexible mutual disabling of layers Do not use IE for it since it will complain about some "console.log()" calls.
