Description

Hi, I'm noticing that there are quite a few places where attempting to access an item at a position that isn't valid (i.e. there isn't anything there) causes segmentation faults. For example if I create a WComboBox which is populated with items from the database, and there isn't anything in that specific table, if I try to use WComboBox~~itemText(0) it crashes, and I am finding that I have to make sure that items exist everywhere~~ the workaround I used here was to check if WComboBox->count() was equal to 0.

Is this the intended functionality? If so, the documentation should reflect this.

Hey,

Wt follows the same conventions as the standard library: i.e. we do not check (or warn) against out-of-bound indexation.

I agree we should add this somewhere to the documentation.

Regards,
