AEScreen filter old data with "Use alert class fontstyle"

Hi all,

I have a problem with historical alarm archived.
The problem is the following :
I have created into "_AlertClass" a new datapoint with the config "_alert_class".
Into the config I have set the "Alert priority", "Short sign" and I have choosed "Not acknowledgeable" ack. type because we don't use the acknowledgment alert. So I have set different colors for background and foreground for "CAME/disabled" and "CAME/acknowl."
CAME/disabled means when an'alarm went .
Then I have created into "A&E - Row/Management" a new "Screen configuration" with own properties for filter the alarms of the last week.
Into the tab "Alert" of the "AES Table configuration" I have checked "Use alert class fontstyle".
When I have simulated the status of the alarm (0-->1;1-->0;0-->1;1-->0.....) until the alarm is CAME (true), the style into the aesrow is correct but when the alarm is WENT(false) the style change but also for the alarm when was CAME.
I have set for the CAME style background-color : blue and forecolor : white; for the WENT style background : grey and forecolor : blue.
I would expect to see in the historian the colored line with the "CAME" style when the alarm was active and with the "WENT" style when the alarm was reset.
I do not know if I'm wrong or something has been thought of in this way.

When querying for historical alert the AEScreen does not show the alarm colors.
The alarm colors are only shown for the pending alerts in the AEScreen.

So it was just as I thought. I thought I was wrong something myself.
thanks for the reply in a short time.

So now my historic alarm list has white font on white background for inactive alerts (WinCC_OA\3.17\panels\vision\aes\AEScreen.pdl) .
I can read the texts by selecting the rows, when the row turns blue, but otherwise it is all blank white.
How should this be fixed?
