Nested UIData doesn't work with command broadcasting

Question

In November 2004 I submitted the bug report below, and I also reported it on this forum. Other than the automated acknowledgment, I have received no followup. The posting on this forum seems to have been deleted. I'm re-posting it here in case it can be of help to someone, as I've noticed others mentioning nested UIData problems.
The JSF RI UIData caches its data model, which can cause problems if the UIData value references some row data in an outer UIData if two UIData are nested. The RI tries to compensate for this by removing the cached information during certain instances such as encoding and decoding. But the RI neglects to uncache during event broadcasting.
When UIData iterates over its data set (during encoding or decoding, for instance), it iterates through the row index which, after loading the data model, places the correct variable in the request map. Because the data model is cached, the inner UIData would return an unpredictable data model---the data model from the last iteration, for instance, not the data model based upon the outer data model's current row.
UIData compensates for this during encoding and decoding by checking to see if it is nested inside another UIData. For example, within UIData.processUpdates() you'll see:
if (isNestedWithinUIData()) {
    model = null;
}This allows a test case to render correctly the nested data set, and even allows a UICommand to queue an event when it is selected. However, UIData.broadcast() does not clear the cache, so by the time the event is actually broadcast, the data model for the row is still set at some other row.
Adding the above code to UIData.broadcast() solves the problem.
(I'm suspicious of this whole caching thing in UIData anyway---what if I construct my own UIData-like thing and nest a UIData inside it? How would I keep UIData from caching its data?)

Answer 1

All right, I've found a solution; I'll post it for anyone in need. It's not particularly elegant but still functional.
First of all I've created a .cmd file in the folder where is located the executable of my interest.
In it, using notepad, I've written as following:
start /affinity 8 FreeTrack.exe
ping 1.1.1.1 -n 1 -w 2000 > nul
wmic process where name="FreeTrack.exe" CALL setpriority 256
Note that the /affinity command is optional and not required (however, I needed it). Replace "FreeTrack.exe" with the name of your executable.
The ping part pings a fake IP once and then waits 2000 milliseconds (set a higher waiting time if this one doesn't work).
The third line changes the priority for all the processes under the name of "FreeTrack.exe" to, in my case, realtime.
Priority legend:
Low: 64 Below Normal: 16384 Normal: 32 Above Normal: 32768 High: 128 Realtime: 256
Since the command prompt window appears for 2 seconds and I don't like that, I've created a .vbs file in the same folder of the .cmd file and executable. This hides the cmd window.
I've put the following into the .vbs file (edited with notepad):
Set WshShell = CreateObject("WScript.Shell" )
WshShell.Run chr(34) & "FreeTrack.cmd" & Chr(34), 0
Set WshShell = Nothing
Replace "FreeTrack.cmd" with your .cmd file name.
I've then created a shortcut on the desktop to the .vbs file and changed the icon to the one of the executable.
Surely this solution won't work if the program keeps reverting back its priority while running.
