Event FPM_NAVIGATE --> FPM_START and Singleton Instance

[stefan_kagelmacher]

Hello,

I have a FPM Application with some views and UIBBs. For transfering data from one UIBB to another I use a singelton instance. This instance will be created at first time. In my ATS UIBB there is a column Link To Action. After clicking the Event FPM_NAVIGATE is processing. In the new page (Event FPM_START) the singleton instance is cleared ?!?!

Is this normal behavior? If yes, how can I store the singleton instance, cause it saves my obligatory data.

NOTE: The new page will be open in a new browser TAB and the new event does not hold the parameter setting in the prev page.

THX and best regards.

Stefan

Hello Stefan,

each browser window (or tab) is assigned with a different backend session. So your singleton isn't available in the 2nd tab - you can't pass data on the server-side via the standard session memory.

To pass data you either have to pass it client-side (as URL- or Post-Parameter) or on the server-side by persisting it in the database or by using shared memory.

Best regards,

Christian

THX for answering.

Do you have an example or tutorial for data passing via URL?

Hi Stefan,

are you sure the class is a singleton? Could you check the instance ID number in the debugger and compare it. I am sorry, this is just to check and be sure ...

Cheers.
