TreeSelect corrupts original data

[plandem]

I don't know why, but i'm losing my data after render of TreeSelect. Here is usage:

            <Form.Item>
              <TreeSelect className={`${prefixCls}-value-input`}
                          dropdownClassName={`${prefixCls}-value-dropdown`}
                          showSearch
                          treeLine
                          value={id}
                          treeData={tree}
              treeDataSimpleMode={{id:'id', pId:'parent_id', rootPId:null}}
                          dropdownMatchSelectWidth={false}
                          filterTreeNode={filterTreeNode}
                          showCheckedStrategy={TreeSelect.SHOW_ALL}
                          searchPlaceholder={searchPlaceholder || formatMessage(messages.searchPlaceholder)}
                          placeholder={valuePlaceholder || formatMessage(messages.valuePlaceholder)}
                          onChange={(id) => this.handleChanges({ id })}/>
            </Form.Item>

If i'm using it like this, then my tree array will be cleared. But if i'm using like this:

                          treeData={tree.concat()}

Then everything is ok. I'm sure it's not correct behaviour.
