Base layer hides other layers.

[PascalKerbrat]

I have two layers, one with multiple layers and another that is my base layer.  When all layers are visible the base layer hides the other layer.  The other layer is still there however, it is under the base layer.  When base layer is set to be invisible (unchecked) the other layers are can be seen.  This starting happening after I upgraded ArcGIS Server from version 9.# (I think 9.3) to 10.  I am using Javascript API version 1.4. 

The map is suppose to look like this:

[ATTACH=CONFIG]12658[/ATTACH]

But it looks like this:

Here is the code for the button that performs show and hide layers:

function updateLayerVisibility() {             //Aerials layer         if ($("#ortho").attr("checked") == false) {             mapLarge.removeLayer(wmsLyr);            }         } else {             mapLarge.addLayer(wmsLyr);             mapLarge.reorderLayer(wmsLyr.id, 0);             }         }                  //Other layers         var inputs = dojo.query(".list_item"), input;         visible = [];         for (var i=0, il=inputs.length; i<il; i++) {           if (inputs.checked) {             visible.push(inputs.id);           }         }         dynamicMapServiceLayer.setVisibleLayers(visible);          }

function InitLargeMap() {     esriConfig.defaults.map.sliderLabel = null;      mapLarge = new esri.Map("mapLarge"); //, {spatialReference:3424});           curLat = 38.91082763671875 + ((41.34429931640625 - 38.91082763671875)/2);  curLng = -75.5474853515625 + ((-73.9544677734375 - -75.5474853515625)/2);        //init toolbar     toolbar = new esri.toolbars.Navigation(mapLarge);    mapLarge.reposition();   $("#mapLarge").hide();      //layer dialog  $.ui.dialog.defaults.bgiframe = true;  $("#mapLayerList").dialog({ position: [625, 125], height: 250, zIndex: 999, stack: false});  HideLayerList();  $($($("#tblLayers").parent().parent()[0]).siblings(".ui-dialog-titlebar")).append("<img id=\"btnMinMaxLayer\" onclick=\"ToggleLayerList()\" src=\"images/maximize.png\" />");  //$(".ui-dialog-titlebar").append("<img id=\"btnMinMaxLayer\" onclick=\"ToggleLayerList()\" src=\"images/minimize.png\" />");

For anyone else who has this problem this is the solution.


.show() and hide() worked!!

function updateLayerVisibility() {     if ($("#ortho").attr("checked") == false) {         wmsLyr.hide();      } else {         wmsLyr.show();     } }
