Hi,

normally you have to consider that your node is black box

it will take value from input attributes compute some data and write it on your output attributes

so you have to be careful not to write anything on your input attributes as it will do infinte loop  .

what are you trying to achieve?

some time to set default value you can use postConstructor ()

or connectionMade
