    Seems like loadISC doing it's job fine, but after loadISC, all the script files are loaded once again by etgcrm.nocache.js (which contains call to initsc.js), browser log:

    You can see, that there are dublicate calls to all ics js-files without verson nunmber parameter => they are not loaded from browser cache.

    Removing <isc:loadISC/> from main jsp (and manually setting isomorphicDir) leaves single load of scripts, but still without version number parameter.

    Do i miss something?

    TY.

    You can either:

    a) use *NoScript versions of the SmartGWT modules you are inheriting and add manual <script> tags to your host .html files with match versions

    OR

    b) set isc.addVersionToLoadTags to false in server.properties

    Adding a version to the URL can make upgrades easier (no possibility the client is caching old versions).

      Thanks, inheriting SmartGwtPowerNoScript while continuing using

      <isc:loadISC skin="Graphite" useSimpleNames="false"/>

      at the main page helped.

      But now i have two warnings in the developer console:

      Code:
      06:00:41.676:INFO:Log:initialized
06:00:41.911:WARN:Log:New Class ID: 'IAutoFitButton' collides with ID of existing Class object '[Class IAutoFitButton]'.  Existing object will be replaced.
06:00:41.911:WARN:Log:New Class ID: 'HeaderMenuButton' collides with ID of existing Class object '[Class HeaderMenuButton]'.  Existing object will be replaced.
06:00:47.739:INFO:Log:isc.Page is loaded
      There were no warnings, while i was inheriting SmartGwtPowerNoTheme.

      Should i consider it a problem?

        That probably indicates two skins, or two copies of the same skin, are being loaded. Look for two loads of load_skin.js.
