研究方向

The bug report indicates that the selector component in demo general does not allow custom keys after setting an expression, only supporting default 'label' and 'value'. Explore the Selector component's implementation in the demo general directory, focusing on how the expression result is processed and mapped to the component's options. Check the relevant source files, such as those handling expression parsing or data binding, to understand the current fixed key mapping. Investigate whether there is a configuration option to specify custom keys, and if not, propose an extension to the expression handler that allows users to define custom key mappings (e.g., using a mapping object). Review any existing comments or linked issues for prior discussion on this limitation.
