[Paraview] [pv2.5] Contour : invalid data range

[fred]

Hi the list,

Let me explain what I am doing :

First.
a) Open Data -> load an Unstructured Grid data
b) Click on "Generate isolines or isosurfaces." button in the toolbar.
c) That displays
    Input: Ev.vut (XMLUnstrucutredGridReader0)
    Scalars: Ev_scal
    Scalar Range: 0 to 1.708325
    Contour Values: 0.854163

which sounds good.

Now, second.
a) Open Data -> load an Unstructured Grid data
b) Choose Filter -> Outline
c) ** I click on Ev.vut (XMLUnstrucutredGridReader0) **
d) Then I click on "Generate isolines or isosurfaces." button in the
toolbar.
e) That displays
    Input: Ev.vut (XMLUnstrucutredGridReader0)
    Scalars: none             <- ???
    Invalid Data Range    <- ???
    Contour Values: 0.854163

One can notice that Contour Values field is still right.

What does it mean ??

Cheers,
