[Paraview-developers] WG: Paraview with python problem

[Lodron, Gerald]

So, things seem to come to an end:

(I selected the Sphere source and pressd Apply)

vtkObjectBase *vtkCubeAxesRepresentationClientServerNewCommand()
{
  return vtkCubeAxesRepresentation::New();
}

Of vtkCubesAxesRepresentationClientServer @ 13

Where the New() seems to close my app. I then debugged to the constructor of vtkCubeAxesRepresentation  at

this->CubeAxesActor = vtkCubeAxesActor::New(); on line 50

and then I came to the constructor of
vtkCubeAxesActor.cxx on line 131:

    this->XAxes[i] = vtkAxisActor::New(); 


I must now go home and will restart the debugging tomorrow but any idea why the standard New function of vtk could fail?

Best regards,
Yours 
Gerald

Ok forgot my last mail, it is not the vtkSMProxyManager, it is the vtkSMSessionProxyManager where it jumps in and the name string of name.toAscii().data(); is correct

It closes in vtkSMSessionProxyManager:: RegisterProxy at proxy->CreateVTKObjects();, I will debug forward....

It closes in 

pxm->RegisterProxy("representations", pcTest, reprProxy);

at pqObjectBuilder.cxx at line 527, and when I set a breakpoint into registerProxy of vtkSMProxyManager it gets never hit. It seems that the name.toAscii().data() is corrupted, but name is a vaild string "DataRepresentation1". When I write

const char* pcTest = name.toAscii().data();
  //pxm->RegisterProxy("representations", name.toAscii().data(), reprProxy);
  pxm->RegisterProxy("representations", pcTest, reprProxy);

and watch at pcTest it is " îþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþÓ6

¡~
hêèXlø" so it seems that:

Name.toAscii().data() is not allowed in that combination OR The memory is completely corrupted from somewhere else......

Weird. Let's try this, but a break point in that method. It'll only be called once after you hit "apply". Then step into the code, including createDataRepresentation(..). If you cannot step, I think it's a problem with mismatched/improperly built libraries or something. If the call stack starts making no sense, it's definitely that, and I'd recommend a clean build -- start with an empty binary directory.
