(SHOULD BE EASY) Quick Create Form Clear Lookup

Posted on by DC-23051928-0

Hello People,

I have a Quick Create form in a model driven application.

A user has a choice, and depending on the choice, I set the visibility of a 2 lookup fields.

The issue is, if the person selects a value in a look up, but changes their mind and changes the choice, that look up field value remains...

How can I clear this field?

if (selectedValue !== 848660000) {

// Case when selectedValue is not 848660000

generalRevenueSourceControl.setVisible(false);

generalRevenueSourceControl.getAttribute().setValue(null); // I need to clear the lookup field value

grantSourceControl.setVisible(true);

} else {

// Case when selectedValue is 848660000

generalRevenueSourceControl.setVisible(true);

generalRevenueSourceControl.getAttribute().setValue(null); // I need to clear the lookup field value

grantSourceControl.setVisible(false);

}

I mistakenly put wrong code with obvious issues but here is the current code.

if (selectedValue !== 848660000) {
// Case when selectedValue is not 848660000
generalRevenueSourceControl.getAttribute().setValue(null); // I need to clear the lookup field value
generalRevenueSourceControl.setVisible(false);
grantSourceControl.setVisible(true);
} else {
// Case when selectedValue is 848660000
grantSourceControl.getAttribute().setValue(null); // I need to clear the lookup field value
grantSourceControl.setVisible(false);
generalRevenueSourceControl.setVisible(true);
}

After talking to my rubber duck, I figured this out...
Like I said.. should be easy.
My logic was off, I had to set the fields to null outside the 'selctedValue' if statement..

if (typeAttribute) {
var selectedValue = typeAttribute.getValue();
generalRevenueSourceControl.getAttribute().setValue(null);
grantSourceControl.getAttribute().setValue(null);

if (selectedValue !== 848660000) {
// Case when selectedValue is not 848660000
generalRevenueSourceControl.setVisible(false);
grantSourceControl.setVisible(true);
} else {
grantSourceControl.setVisible(false);
generalRevenueSourceControl.setVisible(true);
}
}
