[Openfx-developer] parametric parameter

[<fab...@fr...>]

Hi,

In the openfx 1.2 documentation, there is a parametric parameter example which uses the param instance to set the default values.
http://openfx.sourceforge.net/Documentation/1.0/Reference/ch09s10.html

  // set a default curve, this example sets an invert 
  OfxParamHandle descriptor;
  gParamHost->paramGetHandle(paramSet, "lookupTable", &descriptor, NULL);
  // ... and sets values using this instance (parametricParamAddControlPoint)

But in the documentation of the "paramGetHandle" function, it's written:
"You cannot call this in a plugin's describe function, as it needs an instance to work on."

I'm not sure which part of the documentation is wrong. As it's clearly written about parametric parameter:
"The major complication with these parameters is how to allow a plug-in to set values, and defaults. The default default value of a parametric curve is to be an identity lookup. If a plugin wishes to set a different default value for a curve, it can use the suite to set key/value pairs on the  m descriptor of the param. When a new instance is made, it will have these curve values as a default."
I suppose it's only a problem about "paramGetHandle" documentation.
