optional DropDowns
Hi, I have a problem with an webform containing several dropdowns. Each dropdown is getting a (shared) object and one of the objects (int) properties as model. This way I can set the properties width and height of the object box. Now the drop downs are supposed to be optional... and when no item was chosen a default value should be applied. Not choosing an item from the dropdown and submitting the form resuts in an error saying that 'null' could not be set for the property of the model... How can I make that work? thank you for your help in advance! - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi Björn You should probably either switch from int to Integer (which can be null) or provide an own values list which includes your default entry for example with value -1 (or customize the DropDownChoice to do that) Matt Björn Tietjens wrote: Hi, I have a problem with an webform containing several dropdowns.

Hi thank you for your help. I did switch from int to Integer and it works fine now.
