Retrieving slider domain

Hi,

I'm trying to write a script to retrieve slider's domain.

Being a total newbie in the languages used by GH, I tried to fix some Python I found on the web. It works, but only for sliders that are created after the python component itself. Also sometimes with the existing ones, but that looks really random, I can't figure out why.

Any idea ?

Here is the code I used :

"""
Retrieve a named slider's domain.
    Args:
        Sliders: Slider NickNames.
        Update: Set to 'True' to update information.
    Returns:
        Start: Slider domain start.
        End: Slider domain end.
        Domain: Slider bounds as domain.
"""
 
# Name component
ghenv.Component.Name = "Slider Domain Retriever"
ghenv.Component.NickName = 'Slider Retriever'
 
# Import libraries
import Grasshopper as gh
 
# Get to the GH objects
gh_objects = ghenv.Component.OnPingDocument().Objects
 

ghenv.Component.Params.Input[0].NickName = "Sliders"
ghenv.Component.Params.Input[0].Name = "S"
ghenv.Component.Params.Input[1].NickName = "Update"
ghenv.Component.Params.Input[1].Name = "U"
ghenv.Component.Params.Output[0].NickName= "Start"
ghenv.Component.Params.Output[0].Name= "Start"
ghenv.Component.Params.Output[1].NickName= "End"
ghenv.Component.Params.Output[2].NickName= "Domain"
#ghenv.Component.Params.Output[3].NickName= "Value"


 
if Update:
    # Iterate objects
    for obj in gh_objects:
       
        # Set the named slider values
        if obj.NickName in Sliders:
            # Get [Number Slider] objects with NickNames
            if type(obj) is gh.Kernel.Special.GH_NumberSlider:
               
                # Find mininimum and maximum values
                Start = obj.Slider.Minimum
                End = obj.Slider.Maximum
                Domain = str(Start)+' to '+str(End)
                #Value = obj.Slider.Value
                
                # Update slider information
                obj.ExpireSolution(True)
