Cyclic dependency with 'get' and 'set' Store

[dizpatcher]

Hello. I have DataTable, Cytoscape graph and Store with ‘get’ and ‘set’ methods.
Using DataTable, I change graph-stylesheet - I call back ‘get’ Store (for reading cell and applying new style). And then I want to do ‘undo’ operation → I need to use ‘set’ Store for return previous value of style in the cell, but Dash throw ‘cyclic dependency’ error.
I have an option of adding ‘Apply’ button after I change cell value to create a gap, but this variant is ugly and I would like to to apply changes after one click on cell.
I will be grateful for any suggestion to avoid the cycle.

Hi,

Could you provide a small example of your code? It will be easier to understand what your problem is.

You might want to try the cyclebreaker transform,

Thank you for your answer.
It looks like the solution of my problem. But when I tried this I got an dash.exceptions.InvalidComponentIdError because I use compound IDs (with MATCH) - the dictionary, and traceback returned me ‘Characters ., { are not allowed in IDs.’
Maybe you have come across this? How can I get around this?

In the ‘update_table’ callback I use “set storage” as an Input - last string before function definition.

In the __undo I am going to restore previous table state and use “set storage” as an Output - first string of decorator arguments
