Change default value of a CDF parameter

I have a CDF parameter where I want to change the default state of. The cdf already exists so the default state is already defined.

The parameter is a boolean and the default is t. But when I want to change this with parameter~>value=nil I get following warning:

*WARNING* Effective CDF parameter 'paramName', cell 'testCell', library 'testLib',
'defValue' field must be specified.

I suppose if it's already there that it's also specified. So is it not possible this way to change the default value of an existing cdf parameter?

Of course. You use:

cdf=cdfGetBaseCellCDF(ddGetObj("testLib" "testCell"))
cdfFindParamByName(cdf "paramName")->defValue=nil

You didn't show what you were actually doing, so it's hard to guess what you did wrong.

Some parameters need their default changed, I do:

cdf=cdfGetBaseCellCDF(ddGetObj("testLib" "testCell"))
foreach(parameter cdf~>parameters when(condition parameter~>defValue=nil))

This produces the error.

I noticed in my initial message above I wrote parameter~>value=nil, this should of course be parameter~>defValue=nil

I just tried to use cdfFindParamByName to change the default value, it generates the same error.
