Primefaces DataTable我在输入中需要添加时无法删除行

Question

i'm using JSF 2.8 and primefaces 6.0 i have a datatable with 2 actions update and delete. and i have a popup which contains a form with required fields displayed by clicking on the create button.

but when i click on the button delete on datatable the line is not deleted and and a message appears that contains the attributes (of the popup) should'nt be null.

But when i remove required from inputs it works.

While it's an action to delete the line has nothing to do with my form.

Here is my XHTML

Answer 1

Use the process attribute:

<p:ajax process="@form" update="...>

Because the <p:ajax process> and <f:ajax execute> defaults to @this and the modifications won't be executed.
