Dynamic Map Service and Feature Layer

Good morning.

I have a JavaScript application that uses both a dynamic map service layer and a feature layer.  if I render the map, with just the feature layer, everything displays fine.  However, if I add the dynamic map service layer to the map, as well, the map is pushed down on the page.  If I use CSS to modify the position of the map (using negative margins), the map is almost functional, but clicking on the map generates incorrect data -- if I click on Ohio, I will get the data for a State that is more South than Ohio.  I assume that this is due to the re-positioning using CSS, as this behavior is absent when I just have the feature layer on the map.  Any thoughts on any of this?

Thanks...Chris

Hi, Jake.  Both the DynamicMapServiceLayer and the FeatureLayer have the same projection, but they had different extents.  I specified the extent and now the map appears correctly, without the gap at the top.  Thanks for the hint!

Hi Christopher,

This sounds like this could possibly be a projection issue.  Would you be able to post your code?
