Custom calculator function gets objects as arguments instead of values when called from Assembler

Hi

I have simple custom calculator function that creates two points wave. The code is below.

This function called like this

makeLineWave(t1 t2)

Where t1 and t2 measurements calculated before.

t1=1

t2=VAR("tt")

Where tt is test variable

The function working fine when called from the calculator.

But when the function called from Assembler results view it fails because x2 is a wave objects lile srrWave:0x64b93a80

What is the proper way to handle this?

procedure( makeLineWave( x1 x2)
  let((xVec yVec wave )
    wave=drCreateEmptyWaveform()
    xVec=drCreateVec('double 2)
    yVec=drCreateVec('double 2)

    printf("%L %L\n" x1 x2)

    drAddElem(xVec x1)
    drAddElem(xVec x2)
    drAddElem(yVec 1.0)
    drAddElem(yVec 1.0)

    drPutWaveformXVec( wave xVec)
    drPutWaveformYVec( wave yVec)
  wave
);let
);procedure
