Hi Jonas, Yes, the iframe (std) linker was the only official primary linker set up to handle code splitting. I only use that linker and haven't dug too deeply, so I don't know if that was done because of a fundamental problem, for performance/efficiency reasons, or if was just left as an exercise to developers since there wasn't much of a call for it. If it's one of the latter two, it shouldn't be hard to adapt code from the iframe and selectionscript linkers and incorporate it into a version of the xs linker. If you aren't already familiar with it, the key method is doEmitCompilation() in SelectionScriptLinker. CompilationResult artifacts have a String array of the js code associated with that permutation, each entry containing a code fragment. The linker prepares the primary fragment to load correctly, but subsequent fragments are just output directly to a matching subdirectory. http://www.google.com/codesearch/p?hl=en#A1edwVHBClQ/dev/core/src/com/google/gwt/core/linker/IFrameLinker.java http://www.google.com/codesearch/p?hl=en#A1edwVHBClQ/dev/core/src/com/google/gwt/core/ext/linker/impl/SelectionScriptLinker.java -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
