//showLayers: null, <- PROBLEM!
groupName: "Test layer", <- I don't know
Set layer groups to "Group is visible at startup"
*Read in Dev's guide about layer visibility!*
Use the example I have given, modify it for you map. Change ONE thing at
time and see results. You will find the error.
Ha!
Set [this always gives problem to - i never remember!!!]
*useAsyncOverlay* in params
set
*useOverlay* in options
For ovelays use mapname/session, not mapdefinition
var params = {
* mapname: 'TestMap',*
* session: ........................your sess................*
BEHAVIOR: 2,
hideLayers: hideLayersVar,
* showLayers: ......................................all the
layers to show...........................................*
}
I have never used the other params you set, and I don't know if they are
needed/used [see OpenLayers source code to find answer]
var options = {
singleTile: true,
isBaseLayer: false,
visibility: true,
transitionEffect: "resize",
useAsyncOverlay: true,
*useOverlay:true*
}
I have never used the other opts you set, and I don't know if they are
needed/used [see OpenLayers source code to find answer]
Do you have a base layer set before your test layer? without OpenLayers
won't work.
You must at least set:
OpenLayers.DOTS_PER_INCH = 96;
var extent = new OpenLayers.Bounds(........................extent of
map.....................);
var mapOptions = {
maxExtent: extent,
maxResolution: 'auto'
};
var map = new OpenLayers.Map('xxx', mapOptions);
ADD A BASE LAYER [OpenLayers speaking]
I repeat: Use the example I have given, modify it for you map. Change ONE
thing at time and see results. You will find the error.
