Also reproduced by creating a source file such as:
struct A {
struct B {
struct C {
static int k;
int h() { return k; }
} c;
static int j;
int g() { return j + (new B)->c.h(); }
} b;
static int i;
static int f() { return i + (new A)->b.g(); }
};
void func() {
A* p = new A;
p->f();
}
Next perform a Remote Call Hierarchy on "func()". When you try to expand the results you should see the exception.

a code patch applied to rdt.core
The problem is because the updated CH or TH view try to add a type label to variables, but the variable node created by ast binding has a null type. Fix it in VariableDeclaration class.
The fix is checked into cvs, please verify it by the next build. The server update is needed for verification. |

org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) Reproducible: Always Steps to Reproduce: 1. Create a new Remote C/C++ project 2. Add a source file called config.cpp with the contents: #include "header.h" class Small: public Big{ Small(){ Big(); } }; int main(){ foo(); return a; } Create a header file in a folder outside of your project folder called header.h with the contents: class Huge{ }; class Big: public Huge{ public: Big(){} private: int i; }; int bar(); int foo() { bar(); }; 3. Add the folder that contains the header file to the Paths and Symbols property page. 4. Re-index the project 5. Right-click on "Big" in the line "class Small: public Big{" and choose "open Type Hierarchy", you should then see the NPE Another way is to do a type hierarchy on "Small" and double click on "Big" in the Type Hierarchy view.
