[vtkusers] CONTINUE_EXECUTING with vtkinformation

[Felipe Bordeu]

Hello,

I have a source (home made reader) that is capable of generate data 
depending on some options.
I like to  control theses options using a filter way down in the 
pipeline. This means that I would like to send a vtkinformation upstream 
in the pipeline and also iterate for different values of this options. 
Something like the TemporalStatistics filter but not over time.

Till now, I tried to use the 
vtkStreamingDemandDrivenPipeline::CONTINUE_EXECUTING information (in the 
filter) to iterate over the data. My filter is re-executed but my source 
get executed only once.

Also tried to set a vtkInformationDoubleVectorKey to the inputVector in 
the RequestUpdateExtent() of my filter with some data but this 
information is never passed upstream.

Is this possible??? or we can do this only for time.

Thanks for all
Felipe
