PROVISION_TABLE_SEARCH_FIELDS_MISMATCH 用于 IBM Mobile First JsonStore 初始化

Question

我正在使用 Javascript JSONStore 在 IBM Mobile First Platform 8.0.0 中初始化 JsonStore 集合。我面临的问题是以下代码在某些设备上运行良好，而对于某些设备，它是否出现以下错误。

IBM MFP 8.0 中的 JsonStore 初始化是否遗漏了任何内容？任何帮助将不胜感激。

错误消息“PROVISION_TABLE_SEARCH_FIELDS_MISMATCH”可能发生在

搜索字段不是动态的。在调用带有新搜索字段的 init 或 open 方法之前，如果不调用 destroy 方法或 removeCollection 方法，则无法更改搜索字段。如果您更改搜索字段的名称或类型，可能会发生此错误。例如：{key:'string'} 到 {key:'number'} 或 {myKey:'string'} 到 {theKey:'string'}。
