I have web application built on JSP, with dojo included on each page it is used (almost every page).
If during browsing i am not waiting for pages to fully load and navigate to another one,
dojo throws a java script exception

"Error: dojo.body() is null or not an object"

As far as i understand dojo thinks it is loaded but navigating to another page spoils it's plannes.

this function throws this

onload: function(){ 
	// summary:
		//		Function that detects if we are in high-contrast mode or not,
		//		and sets up a timer to periodically confirm the value.
		//		figure out the background-image style property
		//		and apply that to the image.src property.
		// description:
		//		This must be a named function and not an anonymous
		//		function, so that the widget parsing code can make sure it
		//		registers its onload function after this function.
		//		DO NOT USE "this" within this function.

		// create div for testing if high contrast mode is on or images are turned off
		var div = document.createElement("div");
		div.id = "a11yTestNode";
		div.style.cssText = 'border: 1px solid;'
			+ 'border-color:red green;'
			+ 'position: absolute;'
			+ 'height: 5px;'
			+ 'top: -999px;'
			+ 'background-image: url("' + dojo.moduleUrl("dijit", "form/templates/blank.gif") + '");';
dojo.body().appendChild(div); // at this line

onload is called from here

dojo.loaded = function(){
	// summary:
		//		signal fired when initial environment and package loading is
		//		complete. You may use dojo.addOnLoad() or dojo.connect() to
		//		this method in order to handle initialization tasks that
		//		require the environment to be initialized. In a browser host,
		//		declarative widgets will be constructed when this function
		//		finishes runing.
		this._loadNotifying = true;
		this._postLoad = true;
		var mll = this._loaders;
		
		//Clear listeners so new ones can be added
		//For other xdomain package loads after the initial load.
		this._loaders = [];

		for(var x=0; x

Thanks in advance
