Mouse cursor offset/SNAPSHOT timeout

deleted-user-VeZur_n9o0OZ — Mon, 31 Oct 2011 14:18:10 GMT

Hey guys,

Quick one...has anybody experienced an offset curser when using tools such as zoom and box select?
For example, I click to draw a rectangle around some features and the box begins to draw a number of pixels away. My spatial ref of all feature layers is 3857 (WGS84 MAS) same as the basemaps. Anyone know a quick fix for this?

For a bonus point: I'm using a SNAPSHOT feature layer to return 4000+ records (time enabled). I've had to cut this down to 3000 as my GET request seems to timeout and return no features otherwise. Can i increase the timeout time? Seems to die after 15secs in firebug. I've tried changing the pooling params with no success in manager.

Thanks all,
James

Hi James,

The first issue you're describing is usually CSS related. It's hard to say exactly what's happening without seeing your markup and CSS.

Your layer timing out should be a red flag. You can increase the default timeout but I would caution against this for a couple of reasons:
-do you want to make your users wait 15-20s(or longer?) for your app's data to load?
-displaying 3-4k features in any browser will likely cause noticeable performance issues

There are a couple of ways to address this:
-start your app at a larger scale so less features are displayed
-use scale dependencies and a dynamic map service to show your data

James, did you ever figure out your first question here? I am having the same issue and coincidentally I am also using a FeatureLayer select (although this issue appears before the selection).

Hey I'm afraid not. I still see a cursor offest from time to time in my apps. More often in Chrome than other browsers. Did you find a fix?

I was able to solve the cursor offset issue by using map.reposition() after any change in my page layout that affected the map div.
