Hey all,
I've already sent an e-mail about this problem, but I'll detail it better.
I'm trying to extend Paraview so that it can write an unstructured mesh to a
file in a specific format, which I call nds. The logic of writing into it is
already programmed, and seems alright.
Well, I am able to build the project of the plugin and generate the dll so that
I can load it with Paraview. When I click to save a model, I see the option to
choose my extension. BUT...when I click OK to perform the operation, I get a
windows-like crash in paraview: "Paraview is not responding...". Windows Vista
lets me debug the program (as I'm working with visual studio 2005), and when
the IDE opens, it shows me the following message:
Unhandled Exception at 0x05572bcb (vtkServerManager.dll) in paraview.exe
0xC0000005: Access violation reading location 0x00000000
The problem is actually in the vtkSMStringVectorProperty class, in the method
setElement, in the statement:
unsigned int numElems=this->GetNumberOfElements();
As I was able to get the writer of the "Examples" Folder to work, I suspect
that the problem is really with my writer, specifically in my writers.xml file.
Had the model of this file change ultimatelly ? I'm asking this 'cause I've
already used this plugin in another version of Paraview.
I'm sending attached my writers.xml file.
Thanks in advance !
Rafael March.
