DartNodeTraverser NPE in editor not in DartC #832
Comments
|
Is this a bug in the compiler, or is there some option/state that Editor ought to be using that we're not? I explored a little bit and the exception is occurring because there is a BinaryExpression whose left operand is null. I'm not familiar with the command-line version. Does it try to resolve the code if there were syntax errors? (Just trying to guess why Editor is seeing this when the command-line tool isn't.) Removed Area-Editor label. |
|
DartC does not resolve if there were parse errors, it quits after reporting them. |
|
There are still NPE's, but they appear to be due to a configuration issue. I honestly would like to see this not consume the "class" token and try to restart parsing from the top level. |
|
Added Accepted label. |
|
Patched it in and works for me. Set owner to @jtmcdole. |

The following code results in an NPE in the editor but not when running dartc:
library('lib');
class Foo {
}x
class Bar extends Foo {
List<int> i;
}
void main() {
new Test().run();
}
Removing 'x' after the curly brace removes the NPE.
