Clear Action and Clear on Display For Stand Alone Parameter

Solved1.79K views27th March 2023action clear database protocol

I'm trying to do something simple which is to clear the value of a parameter when the value of another parameter changes.

I want the parameter to be "Not initialized" rather than empty therefore i don't think this is possible from a Qaction.

I'm currently calling a trigger with two actions a "clear" and "clear on display"

After this executes the value of the parameter is set to "Not initialized" both in the client and server since if i do a GetParameter at this point null is returned.

The issue now occurs if i restart the element since this parameter has the save="true" the values before the clear come back and it shows both in the client and server.

Is there something else i need to do to clear the values in the database??

Indeed the clear action only clears the value in memory.
After the clear actions are done you can add another action 'save' this will push the value to the database.
