(SHOULD BE EASY) Quick Create Form Clear Lookup

(0) ShareShare
ReportReport
Posted on by DC-23051928-0 31
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);  
            }
        }
