…g#7388) ## Cause When graphs are actually exported, several layers of cleanup are applied. Among these is link compression. Any widgets with inputs that aren't used do not have inputs stored in the workflow. This was implemented for backwards compatibility with the old "convert to input" system for widgets. As part of this process, the target_slots on links are rewritten such that they point to the index of the widget as if unconnected widgets did not exist. This "incorrect" state for links is only corrected AFTER a workflow has loaded because the 'fix' method needs nodes to be initialized in order to calculate the correct target_slot This becomes a problem when subgraphs are introduced. SubgraphInputs need to resolve a link to its target slot in order to construct a clone of the linked widget DURING the loading process. Since this target slot is not accurate, this can result in the cloned widget having the wrong type. For a minimal reproduction: - Create a subgraph with an Empty Latent Image with batch_size linked to the Subgraph Input - Export the workflow - On load, the batch_size has step and min attributes which incorrectly correspond to width ## Fix There's multiple possible ways to address this and input on direction is appreciated - Fix links before loading graph - Likely to break with any dynamic state - Fix links, then load graph again - Ugly, bad performance, dynamic state may require multiple passes to correctly ripple - In the Subgraph code, ignore target_slot and instead `.find()` input with matching linkId (proposed) - Promising, but means accepting that state is just wrong sometimes. Another forever footgun. - Entirely remove the input compression - Some people may complain, and old workflows still need to be supported - Only remove target_slot redirection inside subgraphs - Creates ugly logical difference between what happens inside and outside subgraphs. - Still leaves old workflows broken ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-7388-Remove-target_slot-compression-from-subgraph-exports-2c66d73d3650815d8c96c5047958ab67) by [Unito](https://www.unito.io)
Cause
When graphs are actually exported, several layers of cleanup are applied. Among these is link compression. Any widgets with inputs that aren't used do not have inputs stored in the workflow. This was implemented for backwards compatibility with the old "convert to input" system for widgets. As part of this process, the target_slots on links are rewritten such that they point to the index of the widget as if unconnected widgets did not exist.
This "incorrect" state for links is only corrected AFTER a workflow has loaded because the 'fix' method needs nodes to be initialized in order to calculate the correct target_slot
This becomes a problem when subgraphs are introduced. SubgraphInputs need to resolve a link to its target slot in order to construct a clone of the linked widget DURING the loading process. Since this target slot is not accurate, this can result in the cloned widget having the wrong type.
For a minimal reproduction:
