map query in Fusion 2

[Simon Pelicon]

Hi!
Using map.query in Fusion 1.1 does not require geometry parameter as Fusion 2.0. (i use Mapguide Open Source 2.0.2)
Using map.query with Fusion 2.0 without options.geometry returns error:

Invalid argument(s):

        [1] = ""

The AGF text is invalid because it failed to parse into a valid geometry object.</h2>

Invalid argument(s):

        [1] = ""

The AGF text is invalid because it failed to parse into a valid geometry object.

Exception occurred in method MgParseAwkt.ParseAwkt at line 89 in file d:\build\mapguide_open_source_v2.0\build_30.11\mgdev\common\geometry\Parse/ParseAwkt.cpp

If i add geometry to other parameters works ok.

options.geometry = 'POLYGON((6129642 4676854,6776931 4676854,6776931 5042345,6129642 5042345,6129642 4676854))';
options.filter = 'KAPACITET <= 100';
options.layers = 'Bakarnikabal';
options.maxFeatures = 10;
map.query(options);


How should i use query function in Fusion 2.0?



Thanks!

Simon

The query method no longer works the way it used to. Before, it would call Query.php in the backend and allow you to generate a new selection via an alphanumeric filter and/or a spatial filter. The new query method now calls the QueryMapFeatures directly from the mapguide fcgi agent. So basically, the functionallity has it used to exists is no longer present, as far as I can tell.

You can, easily enough, bring back the code from the old query method into the new Fusion 2.0. I copied over the query method from the previous version and named it queryEx and made it use the same callbacks as the query method. It worked fine for me and gave me back the functionality I needed from the API. It's kind of a crummy fix, as my own code needs to work on either pre-2.0 Fusion and 2.0 fusion. Still, it works.
