# PocketBase SDK Auto-Cancellation

## The Problem

PocketBase JS SDK enables **auto-cancellation by default**. Every `create()` and `update()` call to the same collection shares a default `requestKey` derived from method + URL. When two calls to the same collection happen simultaneously (double-click, race condition, rapid re-submission), the second call **auto-cancels the first** and throws:

```
Error: The request was autocancelled.
```

This is surfaced to the user as "Error creating repair order: The request was autocancelled."

## The Fix

Pass `{ requestKey: null }` to ALL mutating PocketBase calls in `pocketbase.js`:

```js
// addDoc
const record = await pb.collection(collName).create(pbData, { requestKey: null });

// updateDoc
const record = await pb.collection(collName).update(docId, pbData, { requestKey: null });

// setDoc (both branches)
return pb.collection(collName).update(records[0].id, pbData, { requestKey: null });
return pb.collection(collName).create(pbData, { requestKey: null });
```

The `getDocs` and `getFullListLegacy` functions already pass `{ requestKey: null }` in their options.

## Belt-and-Suspenders: Double-Submission Guard

Even with `requestKey: null`, prevent duplicate form submissions by disabling the submit button on first click:

```js
function handleFormSubmit() {
    const submitBtn = document.getElementById('submit-btn');
    if (submitBtn && submitBtn.disabled) return;  // guard
    if (submitBtn) {
        submitBtn.disabled = true;
        submitBtn.textContent = 'Saving...';
    }
    // ... submission logic ...
    // Re-enable after success:
    if (submitBtn) {
        submitBtn.disabled = false;
        submitBtn.textContent = 'Create Repair Order';
    }
    // ... success cleanup (clear form, collapse section) ...
} catch (error) {
    // Re-enable in catch block:
    if (submitBtn) {
        submitBtn.disabled = false;
        submitBtn.textContent = 'Create Repair Order';
    }
    // ... error handling ...
}
```

This guards against: double-clicks, keyboard double-Enter, and accidental double-taps on mobile.
