IOOB and null values in ComboBox

[Mario Ivankovits]

Hi!

Hi!

I am having a list of ComboBox entries where the first entry often is „null“, which means e.g. ALL

Now, with 8u40-b04 I am getting IOOB exception when I select a null value in any ComboBox.

I tracked it down to ComboBoxListViewSkin.updateValue where the list of selections is cleared if the ComboBox.getValue() returns „null“.

I see quite a lot of checks against „null“, e.g. in MultipleSelectionModelBase.select(Object), so that a patch might be a lot of work.

Are „null" values not supported?


Best regards,
Mario
