Search panel does not work, if XWiki application context root is not "/xwiki"

When I clicked on Search panel on the home page, I get "Error 500" on the browser..
Finally, I found the following script at URL : http://localhost:8080/xwiki/bin/inline/Panels/Search.
It seems /xwiki context is hard coded here.. After I modified this script, search function worked properly..

#panelhiddenheader($msg.get("Search"))
<form action="/xwiki/bin/view/Main/WebSearch">
<div id="globalsearch">
<input id="globalsearchinput" type="text" name="text" value="$msg.get('panels.search.inputText')" size="15" onfocus="if (this.value == '$msg.get('panels.search.inputText')') value=''; this.select();" onblur="if (this.value == '') value='$msg.get('panels.search.inputText')'; this.blur()"/>
 
<input class="button" value="$msg.get('panels.search.submit')" type="image" src="$xwiki.getSkinFile("go.png")"/>
</div>
</form>
#panelfooter()
