Widget text dissapear after submit button clicked

Morning all,

I want ask to you all, I have a form that contain widgets,

such as autocomplete and date picker widget,

after I filled the form and submit it,

when the rule isn’t fulfilled (ex: name field not filled) and the validation occur,

why the text that i filled to the widget disappear after i submit the form?

but if i use common textfield the text don’t disappear,

how to make the text in the widget not disappear?

thanks b4
