Description Jan Pokorsky 2009-04-16 15:30:20 UTC 
If I nest JavaSource tasks as follows nested tasks still run over the snapshot of the most outer task.

JavaSource.runUserActionTask {
    // document modifications
    JavaSource.runModificationTask {
         String text = CompilerInfo.getText();
         // text without outer task modifications
    }
}

This usecase has worked before rewriting java.source to Parsing API.

It's a complicated problem, the java requirements are different from the requirements of embedded languages, which require the same top level snapshot to 
be used during the whole run.
Comment 2 Rastislav Komara 2009-04-29 13:04:07 UTC 
Reassigning to correct owner.
Comment 3 Jan Jancura 2009-05-07 13:51:57 UTC 
You should create two separate tasks.
JavaSource.runUserActionTask {
    // document modifications
}
JavaSource.runModificationTask {
     String text = CompilerInfo.getText();
     // text without outer task modifications
}

And in the second task you can check version of document.
Comment 4 Tomas Zezula 2009-05-07 14:12:05 UTC 
Do not forgot to update the Javadoc of the JavaSource as it's an incompatible API change.
@since ..... nested task does not see changes from outer task
