Runutime Control Display bug

[zengxiaolei]

What I have done is as follows:

1. Use flexbe_app to run behavior_1
2. After bahavior_1 is completed, keep flexbe_app opening, but run behavior_2 by calling action (http://wiki.ros.org/flexbe/Tutorials/Running%20Behaviors%20Without%20Operator).
3. After behavior_2 is completed, run behavior_1 again by flexbe_app. Behavior works, but no runtime control display in the app. As shown by Fig. 1, on-board status is running and initialization is done, which is really done. Since the display is empty, I cannot continue the next state since a high-level outcome is to be verified as shown in Fg. 2.

I tried to stop Execution and restart behavior for many times, but problem remains.

Thanks for reporting, I can reproduce this bug and will look into it.

It turned out that the FlexBE App worked as intended, but the issue was caused by flexbe_mirror due to improper release of its thread lock. Consequently, it did not send any behavior updates to the App afterwards.

I fixed it with the above commit.
