14-14: Consider adding documentation for modelValue stateThe change to use
modelValuealigns with Vue 3 conventions. Consider adding a comment to document whether this array holds selected node values or node objects.- modelValue: [] + modelValue: [], // Holds selected node values/objects for v-model binding
35-45: Consider adding null checks and type validationThe watcher implementation correctly handles both multiple and single selection modes. However, consider adding null checks and type validation for more robust error handling.

5-5: LGTM! Consider adding migration docs.The change from
state.valuetostate.modelValuecorrectly aligns with Vue 3's v-model convention.Consider adding a note in the migration guide about this change if upgrading from Vue 2, as it might affect existing implementations.

1-67: Add test coverage for deleteTag functionality.The PR objectives indicate that tests haven't been added. Please add test cases to cover:
- deleteTag functionality with check-strictly enabled/disabled
- Multiple selection scenarios
- Edge cases (empty selection, all tags deleted)
Would you like me to help generate test cases for these scenarios?

118-130: Refactor function to improve type consistency and clarityThe current implementation has several issues:
- Inconsistent return types between array and non-array cases
- Implicit dependency on
props.modelValuein non-array case- Function name doesn't accurately reflect its purpose
Consider this improved implementation:
export const getCheckedData = ({ props, state }) => (selected) => { - const checkedKey = [] - - if (!Array.isArray(selected)) { - return props.modelValue ? [props.modelValue] : [selected[props.valueField]] - } else { - selected.length > 0 && - selected.forEach((item) => { - checkedKey.push(item[props.valueField]) - }) - - return checkedKey - } + if (!selected) { + return [] + } + + const items = Array.isArray(selected) ? selected : [selected] + return items.map(item => item[props.valueField]) }Also consider renaming the function to
getSelectedValuesto better reflect its purpose.

25-26: LGTM! API extension follows consistent pattern
The watchValue method is properly integrated into the API object with the required dependencies.
1-1: Verify the watchValue implementation in index.ts
The import statement correctly includes the new watchValue function.
Let's verify the implementation of watchValue in the index file:
✅ Verification successful
watchValue implementation is correctly handling tag deletion in multiple selection mode
The implementation in index.ts shows that watchValue properly handles the tag deletion scenario by:
- Correctly processing the new value after tag deletion through array handling
- Properly updating both the base select component and tree component states
- Maintaining synchronization between the tree's checked state and select's selected items
The function implementation aligns with the PR's objective to fix the "deleteTag not working" issue by ensuring proper state updates when tags are removed in multiple selection mode.

47-47: Verify deleteTag interaction with modelValue watcher
The watcher chain looks correct for handling tag deletion: when a tag is deleted, it should update state.modelValue, which triggers this watcher to call api.watchValue, ultimately syncing the tree's checked state.
Let's verify the deleteTag interaction:
✅ Verification successful
Tag deletion is handled through base-select component
After examining the implementation, I notice that tag deletion is not directly handled in the tree-select component. Instead, it relies on the base-select component (baseSelectRef) which emits updates to modelValue. When modelValue changes, the watcher correctly triggers watchValue which:
- Maps the new values to tree nodes
- Updates the selected data in base-select
- Syncs the tree's checked state via
setCheckedKeys
The interaction chain is complete and working as expected.

14-14: Verify the impact of check-strictly on deleteTag functionality.
The addition of :check-strictly binding could affect the tree's selection behavior. Since this PR aims to fix the deleteTag functionality:
- Please verify that this change resolves the deleteTag issue
- Document the expected behavior with check-strictly enabled/disabled
Let's verify the usage and documentation of this prop:
✅ Verification successful
Based on the code analysis, I can now generate the final response:
The check-strictly prop addition is valid and improves tree-select's functionality
The check-strictly prop is a standard tree component feature that controls parent-child node selection behavior:
- When true: Parent and child node selections are independent
- When false (default): Selecting a parent auto-selects children and vice versa
This addition:
- Properly passes through the
checkStrictlyconfiguration fromtreeOpprops to the underlying tree component - Aligns with the tree component's documented behavior
- Gives users control over whether tag deletion should affect parent/child nodes

Line range hint 136-172: Add null checks and extract duplicate logic
The function has several potential issues:
- Missing null check before accessing data properties in single selection mode
- Duplicate logic with
watchValuefor mapping selected nodes - No error handling for missing refs

} else {
const data = api.getPluginOption(state.modelValue)[0]

currentLabel: node[props.textField],
value: node[props.valueField],
isTree: true

✅ Verification successful
Based on the search results, I can see that the codebase consistently performs null checks before accessing $refs properties. Let me verify the specific pattern for tree-select by searching for its usage:
Let me verify the null check pattern in the tree-select component's implementation:
Based on the code analysis, I can now generate the final response:
Add null checks and error handling for refs access
The code needs to add null checks before accessing $refs properties to prevent potential runtime errors:
} else {
const data = api.getPluginOption(state.modelValue)[0]
+ if (!data || !vm.$refs.baseSelectRef) {
+ return
+ }
vm.$refs.baseSelectRef.updateSelectedData({
...data,
currentLabel: data[props.textField],
value: data[props.valueField],The same pattern should be applied to all $refs accesses in the component:
- Add null check for
vm.$refs.baseSelectRefbefore calling its methods - Add null check for
vm.$refs.treeRefbefore calling its methods - Add null check for data objects before accessing their properties
This follows the established pattern seen across the codebase where refs are consistently checked before use.

Handle single selection mode and value removal
The current implementation has several limitations:
- Only handles multiple selection mode
- Doesn't properly handle value removal (the original bug)
- Potential race condition between
updateSelectedDataandsetCheckedKeys
Consider this enhanced implementation:
export const watchValue =
({ api, props, vm, state }) =>
(newValue, oldValue) => {
+ // Handle value removal
+ if (!newValue || (Array.isArray(newValue) && newValue.length === 0)) {
+ vm.$refs.baseSelectRef.updateSelectedData([])
+ vm.$refs.treeRef.setCheckedKeys([])
+ return
+ }
+
if (props.multiple) {
let initialNodes = []
if (Array.isArray(newValue)) {
newValue.forEach((value) => {
const option = api.getPluginOption(value)
initialNodes = initialNodes.concat(option)
})
}
const selected = initialNodes.map((node) => {
return {
...node,
currentLabel: node[props.textField],
value: node[props.valueField],
isTree: true
}
})
vm.$refs.baseSelectRef.updateSelectedData(selected)
-
vm.$refs.treeRef.setCheckedKeys(newValue)
+ } else {
+ const data = api.getPluginOption(newValue)[0]
+ if (!data) {
+ vm.$refs.baseSelectRef.updateSelectedData(null)
+ return
+ }
+ vm.$refs.baseSelectRef.updateSelectedData({
+ ...data,
+ currentLabel: data[props.textField],
+ value: data[props.valueField],
+ state: {
+ currentLabel: data[props.textField]
+ }
+ })
}
}This implementation:
- Properly handles value removal (fixes the deleteTag bug)
- Adds support for single selection mode
- Adds null checks
