The system works 99% of the time but sometimes when the app has live data on the screens, and the home button is pressed, or they just switch to another process, the data is cleard from the input screens. So when they go back into the app the screens are blank.
Is there a way to stop this happening or to catch the home button and save the data before the app closes.
Regards
Nigel

Also is there any way to record the button clicks/keystrokes etc. so I can check that they are not pressing the wrong options. This would only be for the app and not for the rest of the phone and it is an app for industrial usage, not personal.

Hello Nigel!

Normally, the state of the views are persisted automatically when the app goes to the background.
This is triggered by the different operating systems, e.g. when you press the Home button, switch to another process, the display is turned off after some time of inactivity,....

On which platforms does this happen for you? iOS? Android? Windows? Multiple/all of them?

What do you mean with "the data is cleared from the input screens"? Are specific controls empty or is the whole page blank (i.e. also no cotnrols are visible at all)?

Maybe you can attach a small sample here to reproduce this issue? If you do not want to share it with others, you can also send one to our Support team.
Also some screenshots can be helpful.

Best regards,
AFC

We only use ios, iphones and ipads, and all systems are on the latest release.
The screens clear in that all the users inputs are blank but the actual screen, inputs/buttons/controls etc, are all there.
The system is so large now that I dont think I can attach any code and it can happen at the beginning or end of the app.

Hi Nigel!

Can you tell us a bit more about your solution please?
Is it used in an AppStore App (=did you generate code)?
Which "Server Access" mode (Always/On Demand/Never) do you use?
How large is the solution file approximately?
Do you handle big page source trees (a large amount of DB data, big XML files,....)?

The solution os for heating engineers and is 3.5Mb in size with no data. The solution is just deployed onto a server and they download it from there, it has not been converted into code because it is constatly updating. In general the server access is on demand and it not used within the app until a job is submitted. This is because they are usually in underground areas with on internet access. There are about 50 persistent files because of limited internet access and a couple of xml files upuntil the submission and then a connection is made to the server to update the sql data files. Some of the persistent files would be quite large eg 200 fields and 2000 records in the history file.
I hope this helps.

Regards
Nigel
