    After compile to JS smartgwt component style is missing!!

    Hi, I am using smartgwt menu component. Everything is OK, but when I compile to JS and running at host mode it looks not as expected and just ugly. I think that css style is missing for this component... What can be the cause? Am I missing some row in gwt.xml?
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
<module rename-to='treemenu'>
                   
  <inherits name='com.google.gwt.user.User'/>
  <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> 
  <inherits name='com.google.gwt.user.theme.standard.Standard'/>
  <inherits name='com.smartgwt.SmartGwt'/> 
  <entry-point class='com.treemenu.client.Treemenu'/>
          
  <source path='client'/>
  <source path='shared'/>
</module>
    Thanks!

    Just now understood that this are images, that makes the look of components and they are not found! After compile the folder /sc/skins/standrat is not located at its place, only folder Enterprise with lot of images. Is it compiler issue? Why does create so many unnecessary stuff?

      Also the URL for images is created wrong. I am using spring and when JS creates components images URL it takes dispatcher servlet url-pattern. Is this somehow can be changed in the code or some compile options? Seems compiled JS contains something like getHostPageBaseURL() instead getModuleBaseURL() when creating url for images? For example URL for button image is http://localhost:8080/web-shop/app/t...button_end.png
      but should be http://localhost:8080/web-shop/js/tr...button_end.png
      With just GWT there where no such problems. How to configure this stuff?
      (p.s. I am using eclipse and smartgwt 2.2)

        Please read the FAQ sticky post and then closely examine the Hello World example provided in the Smart GWT distribution.

          smartgwt.dev, thanks for advise.
          But there I didn't find the answer.There is similar issue http://code.google.com/p/smartgwt/issues/detail?id=36 but there is no solution. Only thing I found is to set isomorphicDir, but this doesn't solve the problem. Resources are still loaded relative to the context URL!

            The issue you point to has been resolved. Again, try comparing your sample to the simple Hello World sample distributed with Smart GWT which clearly works.

            The FAQ also mentions not to inherit the Standard GWT theme modules but that does not appear to be the primary cause here.

            If you still cannot figure it out, post your host html file contents as well.

              Everything works perfect until I add all this compiled stuff to my webapp, so I found nothing new in HelloWorld project..
              Once again, this damn resource URLs are wrong :((((

                  host html is your applications .html file, not hosted.html

                  The Hello World sample comes with an ant build file that has a "war" target to generate a war file. Compare the structure of this war with your deployment. Everyone else has gotten Smart GWT to display fine. If you still cannot figure it out, then consider purchasing support.
