I tried stepping through the code to see what’s going on. In VarDeclarationEmitter.emit():
IDefinition leftDef = dyn.getLeftOperandNode().resolveType(getProject()); dyn.getLeftOperandNode() is a MemberAccessExpressionNode of “.” With two sub-nodes of type IdentifierNode. The first is “object” and the second is “coordinate”. resolveType() on that returns null. It seems to go up the scope and as best as I could understand it seems to be trying to resolve it to a member of a class rather than a member of an object literal. But I’m not sure I was understanding what’s going on… I don’t know if this is helpful, but I know that I’m confused… ;-) Harbs > On Dec 24, 2018, at 8:40 PM, GitBox <[email protected]> wrote: > >
