cdf lost every time I log out from cadence

Hi

In my SKILL code (pcell.il), I include pcell (pcDefinePCell()) and CDF
(cdfCreateParam(()).(This is similar to

http://groups.google.com/group/comp.cad.cadence/browse_thread/thread/4791011ed9a6ff40/1d12829648321907).
After I load this pcell.il in CIW, everything looks fine and I can see
the CDF settings. However, every time I restarted cadence, CDF
component parameters are lost.
Can anyone help with me on this issue? Thanks!

Yes. I have these. Basic my pcell.il is as following:

pcDefinePCell(
list(ddGetObj("lib" "cell" "layout")
.......
) ;end of pcDefinePCell


;;CDF Development
let( (libId cellId cdfId (cellLib "libname") (cellName
"cellname") ;;cellLib, cellName, changed as in PcCellViewDefine
)
unless(cellId = ddGetObj(cellLib cellName)
error( "Could not get cell %s." cellName ))
when(cdfId = cdfGetBaseCellCDF(cellId)
cdfDeleteCDF(cdfId))
cdfId = cdfCreateBaseCellCDF(cellId)

cdfCreateParam(cdfId
?name "widthR2"
?prompt "widthR2"
?defValue 2.0
?type "float"
?storeDefault "yes")
.....

);end of let

Similar is maybe not good enough ...

You have to modify the base CDF parameter (supposed you are allowed to).
Do you have (among others) at top:

let( ( libId cellId cdfId )
    unless( cellId = ddGetObj( LIBRARY CELL )
        error( "Could not get cell %s." CELL )
    )
    when( cdfId = cdfGetBaseCellCDF( cellId )
        cdfDeleteCDF( cdfId )
    )
    cdfId  = cdfCreateBaseCellCDF( cellId )

???
