SAP CAP virtual field leads to out of memory

[T1mey]

Hello @all,

we have some trouble with virtual fileds in CAP 7.2.1

virtual isAdmin           : Boolean default false;
virtual appTypeIcon       : String default 'img/phenix_blue.svg';

We're controlling some input fields and switching an icon depending on the type.

It seems that we're ending up in an infinite loop when accessing the object page for some reason.

The Fiori elements UI freezes and ends up in an out of memory exception.

CAP log shows this

In previous versions used our coding worked. Seems to be some problem with 7.2.x maybe.

Or it might be related to the new sqlite package, as we switched to that as well.

Anybody similar problems ?

As a side-note: if I recall correctly you can't specify default values for virtual elements. They should be set via the read handler.

[T1mey]

Please make sure to set the virtual field(s) in your event handler in every case (not only conditiuonal) to a value.

Thanks! I (apparently) solved all my problems by setting default values to virtual fields both in "regular" and in draft mode

[T1mey]

enjoy... took me some time to understand it

[T1mey]

It seems to be related to the new @cap-js/sqlite package.

Thanks in advance.

In my case I assume that it has something to do with a virtual field, because if I remove that the memory problem does not occour anymore.
