EVALUATION The error is: "Test failed. A Button doesn't have a focus." I believe that this could be fixed by focus bug-fix. ###@###.### 2004-11-29 09:54:04 GMT See the evaluation for 6200345. This problem is similar. SetEnabled() is called on native level via InvokeFunction (invoked on Toolkit thread). Earlier we called it directly that was not correct but in the same time it saved us from some native messages (due to asynchronous processing). Now we have that messages and should skip them somehow. ###@###.### 2004-11-30 18:49:26 GMT There is AwtComponent::sm_suppressFocusAndActivation field destined to have an ability to suppress native focus-related messages. We can use this field in this case when disabling/enabling a component allowing "auto focus transfer" mechanizm (that initiated on Java side) to work swimmingly. ###@###.### 2004-12-03 15:25:35 GMT
