Hello,

want to use double click extension function to navigate to a window using the parameter to pass through along with one other parameter to from root window but not able to pass the parameter available from which navigation needs to happen.

I tried the code in the power table double click extension function:

Def Ondoubleclick(self, rowindex, colIndex, ColName,Value,event):#not working  
parma1= value  
param2= event.source.parent.Station\_ID #from template properties)  
system.na.swapto(‘Windows2’,{‘SerialNum’:param1, ‘StnID’: param2})

Def Ondoubleclick(self, rowindex, colIndex, ColName,Value,event):#working fine  
parma1= value  
system.na.swapto(‘Windows2’,{‘SerialNum’:param1})

Can anyone help to why that’s not working…?  
Thanks in advance

Extension functions don’t have the `event` variable. (Copy and pasted from elsewhere?) Use `self.parent.Station_ID`.

Thanks, @pturmel. Already came up with that solution but this helps a lot.
