Let's say a requestor has opened 2 work objects with 2 different threads, is there anyway that we can use 2 locales display the 2 work objects?

Currently, when user open Mashup, we will update the requestor as well as thread's locale according to the selected language. Considering scenario as below:

• Open a thread, and set it's locale to en. Things seem work fine, the UI was displayed with English.
• Open second thread, and set it's locale to zh_CN. The 2nd thread seems work fine either, the UI was displayed with Chinese.
• Back to the 1st thread, do some action to reload section(s), you will find that the 1st thread was displayed as English either.

Is there anyway to keep the 2 threads with 2 different locales?

Thanks.
