         Invoking Linker Cross-Site-Iframe
            [ERROR] The Cross-Site-Iframe linker does not support <script> tags in the gwt.xml files, but the gwt.xml file (or the gwt.xml files which it includes) contains the following script tags: 
sc/modules/ISC_Core.js
sc/modules/ISC_Foundation.js
sc/modules/ISC_Containers.js
sc/modules/ISC_Grids.js
sc/modules/ISC_Forms.js
sc/modules/ISC_RichTextEditor.js
sc/modules/ISC_Calendar.js
sc/modules/ISC_DataBinding.js
sc/skins/Enterprise/load_skin.js
In order for your application to run correctly, you will need to include these tags in your host page directly. In order to avoid this error, you will need to remove the script tags from the gwt.xml file, or add this property to the gwt.xml file: <set-configuration-property name='xsiframe.failIfScriptTag' value='FALSE'/>
