Re: GWT Cross Site Iframe Linker and Script Tags


I know it's an old thread but I used few hours to quickly implement a linker and special entry point class that uses script tags from gwt.xml files and injects them automatically using ScriptInjector. There are few changes required in EntryPoint classes but they are not that intrusive.

Could you tell me if such approach is sensible? Do you see any problems it could cause (except difference in performance - scripts have to be loaded one after another instead of almost concurrently).

I have the same error when running the code server and this limitation effectively prevents me from using superdevmode, as in my case the problem is with an external library that I include which then uses the <script> tag in its own module xml.
Also not being able to use <script> in the module xml breaks encapsulation of modules, as I know have to include all scripts from all libraries in my host page (for me that's implementation details that I don't care about) .

There's ScriptInjector to encapsulate loading within the module's code.
I know superdevmode is still experimental and seriously hope that this will be fixed. In the meantime does anyone have an idea how to work around this? Besides manually patching a 3rd party library...

In your module that enables the SuperDevMode hooks, add the failIfScriptTag configuration property and add an entry-point that uses ScriptInjector to load the 3rd-party scripts. The 2 entry points (from your app, inherited GWT module, and from the SuperDevMode-specific module) will both be executed; beware though that onModuleLoad will be called *before* the scripts are loaded, so your code that depends on them has to wait a bit… There are a couple ways to workaround this if really needed (but it's a bit more "invasive" for your app; that being said, xsiframe is the future, and might becomes the default at some point, so better be prepared –and update your 3rd-party libs–)
