Querying components values might have unexpected side effects, because the value binding would be evaluated when it wouldn't be by the regular JSF life cycle.

Perform the same step on the client side by navigating to the client BLA, CU, and client binding panels.

In any case, you can add and remove keys (on the left side of the editor) and create or change the bindings of any key, as well as remove a binding (on the right side of the editor).
