what are the problems when loading openlayers from single file?
I think we're having some miscommunication based on terms.
The OpenLayers.js loader [1] is a script that is meant for debug or
development environments only. It loads the entire library, one script
at a time, uncompressed. It should only be used when you need to debug
(as it sounds like you do).
The version of this loader shipped with 2.10 does not work in Firefox 4.
This was addressed in r11036 [2] and the fix will be included in the
2.11 release. So, unless you are using the loader from the trunk after
r11036, you should not expect it to work in Firefox 4.
In production, you want to build a concatenated and minified version of
the library. We call this the "single file" version of OpenLayers.
When you build a single file version of OpenLayers, you include the
SingleFile.js [3]. This sets OpenLayers.singleFile to true.
The "single file" OpenLayers always worked in Firefox 4. So, in answer
to your question, there are no problems (related to Firefox 4
specifically) with the single file version.
The problem, again, is with the development/debug loader before r11036
in Firefox 4 only.
If you need to debug a 2.10 release (or anything before r11036) in
Firefox 4, then you'll need to patch your OpenLayers.js loader (with the
change from r11036).
Hope that helps clarify,
Tim

I'm guessing you are testing your application using the debug
loader. This is the OpenLayers.js file that loads all other
library files individually. Versions of this loader from 2.10
and before do not work in Firefox 4.
You can use the latest from trunk to get a fix, or wait for the
2.11 release.
In any case, you should *never* put an application in production
using this OpenLayers.js loader. This is strictly for
debugging/development purposes.
so I shoudn't use OpenLayers as a singleFile. But for me I need to
use it as singlefile because there is problem in loading the library
using require in Wt
reading a singlefile line by line help me to solve loading issue in
chrome and Firefox 4.0pre (Minifield)
Always use a minified build of the library.

this is the chrome error
Uncaught TypeError: Cannot read property 'Vector' of undefined
Is this a bug in OL or chrome?
How to solve it?
the application works fine on Firefox 3.6.6 but not in firefox4
this is the code creating problem
new_layer = new OpenLayers.Layer.Vector("layername_", {
strategies: [new OpenLayers.Strategy.BBOX(),
saveStrategy],
projection: new OpenLayers.Projection("EPSG:4326"),
protocol: new OpenLayers.Protocol.WFS({

})});
map.addLayer(new_layer);new_layer.refresh();
if this is commented out the it works but no output
