[Discuss-gnuradio] Circular dependency caught in sort_variables only String type

Hi,

I'm getting this error with string type variables using gnuradio 3.7.5 and I cannot figure out how to solve it. I'm using a normal variable plus a config variable in this way:

Variable:

   id: variable_A

   value: config_variable_A

Variable Config:

   id: config_variable_A

   ...

   WriteBack: variable_A

This way the variable reads the config file at the start and the variable config writes the latest value of the variable at the end. It works very well with Integers.

When I change the Config variable type to "String" and I generate the flow graph, I get the error:

Generate Error: circular dependency caught in sort_variables

Could anyone please help me to get this behaviour for a String type variable please?

Thank you,

Murray
