Bug: setState_Net().done() on existing schematic netport clears net instead of updating it

[xjxkeep]

Summary

When using the EasyEDA bridge to update an existing schematic netport component, calling toAsync().setState_Net(newNet).done() did not update the net name to newNet. Instead, the net became an empty string ("") when read back with getState_Net().

Creating a new net port with sch_PrimitiveComponent.createNetPort('BI', newNet, x, y, rotation, mirror) works correctly and immediately returns the expected net name.

Environment

• Skill repository/version: easyeda-api-skill v1.1.3
• Bridge: scripts/bridge-server.mjs
• EasyEDA context: schematic page, existing netport primitives
• Host OS: Windows
• Node.js: v24.14.1

Reproduction

1. Open a schematic page containing an existing net port, for example one with net RGB_DB2.
2. Fetch that existing net port with sch_PrimitiveComponent.get(id) or from sch_PrimitiveComponent.getAll().
3. Try to update its net:

const port = await eda.sch_PrimitiveComponent.get('existing-netport-id');
const asyncPort = port.toAsync();
asyncPort.setState_Net('GPIO1_C5_d');
await asyncPort.done();

const check = await eda.sch_PrimitiveComponent.get('existing-netport-id');
return check.getState_Net();

Expected behavior

check.getState_Net() should return:

GPIO1_C5_d

Actual behavior

check.getState_Net() returned an empty string:

In my test, multiple existing netport primitives with original net names such as RGB_DB2, RGB_DB3, etc. were changed to blank nets after attempting setState_Net(...).done().

Workaround

Deleting the original net port and recreating it at the same coordinates works:

await eda.sch_PrimitiveComponent.delete('existing-netport-id');
const created = await eda.sch_PrimitiveComponent.createNetPort(
  'BI',
  'GPIO1_C5_d',
  x,
  y,
  rotation,
  mirror
);
return created.getState_Net();

This returns the expected new net name.

Notes

The issue was observed while replacing RGB_* net labels with the corresponding GPIO* names from U1 pin descriptions. The replacement only became reliable after deleting and recreating the net ports.
