Without this layer everything ok.

I only want to add this layer: mapslt (MapServer)  and some polygons, but isn't work. What's wrong? Could anybody help me?

Hello, I'm very glad for help. I started learn apI thIs week and I don't know a lot. But I'm tryIng me best to make somethIng and I thought You can help me.
So, I want to have thIs basemap: http://www.maps.lt/arcgIs/rest/servIces/mapslt/MapServer and some polygons on It. That's all. I changed what you saId, It works. But polygons doesn't apper. I don't know where the problem Is, It's the second day I'am lookIng for, but I don't found yet.

You should really ask this as a separate question.

The problem you're running into is that you are trying to add a tile layer that has a different projection (3346) than the map's basemap. You can add a dynamic layer or feature layer that has a different projection, but a tile layer is treated differently. A tile layer will only be visible for when it not only has the same projection as the basemap, but also has the same levels of detail (LODs).
