• NullPointerException in Dojo List TextBox

    By Thanh Nguyen 1 decade ago

    Hi,

    I have a problem when using Dojo List TexBox. 

    Currently, I'm using Dojo List TextBox with the Value Picker Control. The Value Picker has a simpleValuePicker dataProvider.

    my dataProvider provides few simple label|value pairs, for example:

    • Human Resource Department | HR_DEPT
    • Database & Software Department | DBS_DEPT
    • Marketing Department | MAR_DEPT

    ...

     

    My Person form has a field named Department bound to the Dojo List TextBox control, and currently have the value MAR_DEPT, and everything is working fine (the Dojo List TextBox display the label Marketing Department).

    But if I deleted the MAR_DEPT from the dataProvider, then the Dojo List TextBox will failed with the NullPointerException. Is there any way to correct this (maybe only its value, because the label|value item has been deleted from the dataProvider).

    Otherwise, I have to search for all the documents that are using the deleted value when deleting a dataProvider's item, only then to remove the invalid reference for the Dojo List Textbox to work.

    I hope to make it clear, and some one can help me out.

    Thanks.
