Problem with Layer Definitions 2.1 Beta

RobChouinard

If there is a forum/forms to submit bugs please let me know. I couldn't find it.

I switched my project from 2.0 to 2.1 Beta and I immediately realized that my layer definitions were not working. No code was changed. I made the move to 2.1 beta to test the layer defs because I was running into a problems with the layer defs length limitation in 2.0.

I started a new 2.1 beta project to test out the examples in the "Layer Definitions Property" in the 2.1 beta API reference. I couldn't get any of the examples to work. Setting the layer defs in XAML or C# did not work.

Possibly a bug?

Thanks,

Rob

By worked I mean nothing is being "filtered". It is the same as a blank layer def. I ran fiddler and I think I found the bug.

The layer definition I set was on layer 0 = Magnitude > 6 so it should look like "0:Magnitude > 6;" before switching the special chars to char code. Below is what I get from both 2.0 and 2.1 Beta.

This is pulled from the GET HTTP request:

v2.0
layerDefs=0%3aMagnitude+%3e+6%3b
which equals
layerDefs=0:Magnitude > 6;

v2.1b
layerDefs=0%253aMagnitude%2b%253e%2b6%253b
which equals
layerDefs=0%3aMagnitude+%3e+6%3b

Looking at this their are 3 extra "25"'s which mess up the character codes. Char code %25 = the % sign.

If these were removed like so:
layerDefs=0%253aMagnitude%2b%253e%2b6%253b

It would be the same as the 2.0 request which is correct.

v2.0 Raw Get Request:
GET /ArcGIS/rest/services/Earthquakes/Since_1970/MapServer/export?bbox=-34844537.1956065,-19971868.8804086,34844537.1956065,19971868.8804086&size=1148,658&format=png24&transparent=true&imageSR=102100&bboxSR=102100&layerDefs=0%3aMagnitude+%3e+6%3b&f=image HTTP/1.1

v2.1b Raw Get Request:
GET /ArcGIS/rest/services/Earthquakes/Since_1970/MapServer/export?bbox=-34844537.1956065%2c-19971868.8804086%2c34844537.1956065%2c19971868.8804086&size=1148%2c658&format=png24&transparent=true&imageSR=102100&bboxSR=102100&layerDefs=0%253aMagnitude%2b%253e%2b6%253b&f=image& HTTP/1.1

Can you share the code you used for LayerDefintions? When you say they do not work, what do you mean exactly? Do you mean the layer shows more than it should? Can you run Fiddler to see the difference between the calls made with API v2.0 and v2.1 beta?

You can either report the bug here in the forums as we check them periodically or you can also go to http://support.esri.com/en/ to submit a bug.
