I think i found a strange bug.
http://webix.com/snippet/fa0fe813
A multicombo crash when all theses conditions are presents :
`
- checksuggest options is a list component
- the list component load data from remote url
- the multicombo is hidden
- setValues method is called on the form that contain it to set value of an other field.
`
When setValues called, it crash : “this->_getBox() is null”.
If the multicombo isn’t hidden, it doesn’t crash
If the list data isn’t loaded from a remote url it doesn’t crash
It also crash without setValues, if you manually set value: null in the multicombo definition
