[CLOSED] Editor field mapping: Missing combobox display text on gridpanel load
Hi,
We have a gridpanel with 2 textfields and 1 combobox columns.
The binding works well but when the gridpanel is loaded all data is dispalyed correctly except for the combobox column which is blank.
The hic is that when I click manually on the "refresh" button of the grid, combobox column content is shown with correct value.
Below a sample in order to reproduce the issue:
ASPX view code :
