empty the form

OK. Seems like a reasonable idea. Do you have any specific problem? Can you share some code?

I tried appending to another local variable and then using a!save to save null values to the local variable whenever I press add it shows the data in an editable grid but it keeps giving me an error do you have a solution for it

Hey, could you kindly provide the code snippet?

I am sure we can help you. But first you need to help us. Follow these guides:

a!columnLayout(
contents: {
a!radioButtonField(
label: "Document Form",
labelPosition: "ABOVE",
choiceLabels: index(rule!ONH_fetch_lookUp(lookUp: "Document Form"),"itemEn",{}),
choiceValues: index(rule!ONH_fetch_lookUp(lookUp: "Document Form"),"itemId",{}),
value: if(a!isNullOrEmpty(local!requestDocument.documentForm),null(),local!requestDocument.documentForm),
saveInto: local!requestDocument.documentForm,
required: true,
choiceLayout: "COMPACT",
validations: {}
)
}
),

a!buttonArrayLayout(
buttons: {
a!buttonWidget(
label: "Add",
iconPosition: "END",
value: append(ri!requestDocument,local!requestDocument),
saveInto: {
ri!requestDocument,
a!save(local!addNewDocument,null()),
a!save(local!requestDocument,null())
},
style: "NORMAL",
validate: if(a!isNullOrEmpty(local!requestDocument),"it is not validate",{})




)
},
align: "START"
)

This is an example whenever I try to null the date or the dropdown does not work.

I think that the issue here is that you put the append into the value for your button. This will not be evaluated at button click. Just use a a!save() as the first line of your saveInto.

Regarding that error message you mentioned, it would help a lot to post it.

And next time, 

Hello abd123 ,

Append will not help you perform your desired action in the Value parameter. Try using in saveInto parameter using a!save().

{
 a!save(
 ri!requestDocument,
 append(ri!requestDocument,local!requestDocument)
 ),
 a!save(
 local!requestDocument,
 null()
 ),
 a!save(
 local!addNewDocument,
 null()
 )
 }
