Ok. But wouldn't that just set the name of the multiblock dataset that
holds all the extracted datasets? I am looking for something like:
multiblock->SetDataName(blockNumber, Name);
And for those names to show up in the gui somewhere I guess.

I am just saying that PV (at least used to) treat partial arrays
specially. It's something to be aware of. In terms of displaying
strings in the UI have you tried to set
vtkCompositeDataSet::NAME() on the leafs? I see that is used by
various readers and recognized by PV, you might look closer at that.

imageData->GetPointData()->SetActiveScalars(record-

multiBlock->SetBlock(blockNum, imageData);
The call to record->getRecordName().c_str() will be different for
each block
that is extracted, based on what the user asked for in the GUI. So
what you are
saying is the name of the Scalars must be the same, for each and
every block? Is there a way to tag a Human readable string onto
each block so that it shows up in the GUI? Lookup table or
something else?

PV expects each block to have the same set of arrays, if an array
is missing from one of the blocks then PV treats it as a partial
array. Are you setting the same arrays in each block?

I have my MultiBlockDataset reader working nicely now. I have a
custom panel that contains a tree view and I can select various
selections from the tree and have "something" rendered in the 3D
view. Awesome. Now, the problems.
When I click on the "Information" tab to see the list of datasets
that were actually read (The Heirarchy Table) the list is
correct. But when I click on one of the data sets and then look
at the "Data Arrays" table the name that appears has a
" (partial)" appended to it. Where is that coming from and what
does it mean?
Also, when I view the data as a "Surface" and then select one of
the listed Arrays to "Color By" the rendered view just stays a
solid color. Actually it looks like as long as I select the top
most array to color by in the list, after the "Solid" and
"vtkCompositeIndex" selections then I will get a proper rendering.
So for example, say I tell my reader to read the following 3 data
sets: Phi1, Phi, Phi2. This will result is a MultiBlockDataset
with 3 blocks. The "Color By" drop down will have the following:
Solid
vtkCompositeIndex
phi1
phi
phi2
If I select "phi1" the rendering is correct. If I select "phi" or
"phi2" then I just get a solid color surface rendering.
Anyone seen anything like this or possibly know what is going on?
I can supply all the source codes and experimental data if that
is needed.
