我已经symfony tutorial嵌入了一系列表单。一切都有效，除了现有的实体移除。
初始数据：
+----+-------+
| id | value |
+----+-------+
| 1 | a |
+----+-------+
| 2 | b |
+----+-------+
| 3 | c |
+----+-------+
然后在收集表单中，我删除a值表单。提交和handleRequest（）后，数据变为：
+----+-------+
| id | value |
+----+-------+
| 1 | b |
+----+-------+
| 2 | c |
+----+-------+
看起来handleRequest（）只是覆盖数组集合值并删除所有差异。预期结果应为：
+----+-------+
| id | value |
+----+-------+
| 2 | b |
+----+-------+
| 3 | c |
+----+-------+
为什么会发生这种情况？
