I have a form with some inputs which has a ViewScoped *ManagedBean* behind. At the bottom of the form I have a CommandButton for saving the data. There is a datatable on the form which new items could be added by entering data to an input and clicking another CommandButton. When user filled all the inputs and added any items to the datatable he/she can click the save button. But I have some problems in controling the add button and updating the datamodel. When I set the immadiate of the button to true the value of the input won’t update and when I set it to false validation error will happen for the rest of the inputs on the form!!!
Code if it helps:
