r11555 added error handling for view nesting problem

comment:4 Changed 10 years ago by ascheibe

Because swagner also had a problem in the optimization networks UI caused by this bug, I implemented checking for the nesting level in ItemView (not ViewHost to cover more cases). Notes:

  • To find out at which nesting level things go wrong, I played around with different UI configurations and found out that somewhere between 37 and 42 parents the layout of the views break or exceptions are thrown.
  • When a certain nesting level is reached, a control is displayed for opening the view as a new tab. There are cases where MainFormManager.MainForm.ShowContent() is not able to find the correct view while a ViewHost can. I'm not sure why this is the case, so we have to have a look at this.

The nesting level should be changed from 37 to 32 to have some space left.
