Directory Multiselect Combo Box

Hi Goran! Great component!

I wrote following test code. Test 1 works very good. But in Test 2 I found a problem. After setting the values in Test 2 and after opening the selection box no element ist selected in the list but “Two” and “Three” should be selected. “Two” and “Three” are shown in the MultiselectBox, but not as selection in the list. With datatype String the box works great, but not with a custom type.

Is this an error or not yet implemented?

Thank you very much,
Thomas

Hi Thomas,

Thank you for the feedback.

That is very interesting.

Have you tried the above test, but with hashCode() and equals() overridden for the LabelValue class?

BR,

Hello Goran,

thank you very much.

Implementig these two methods solved my problem.
