Getting error - as formContext.getAttribute.. is not a function

(0) ShareShare
ReportReport
Posted on by snehaln676 140

Hello,

I have a java script function on load of the form which eventually calls - formContext.getAttribute("new_fieldame").addOnChange(fucntionname).

But on load of new lead form or existing lead form, following error is occurred -

formContext.getAttribute(...).addOnChange is not a function

This error was not occurring on other environment (having same JS, same form), however I could reproduce it by removing that field 'new_fieldname'.

On-load function gets called when complete form is loaded. However, I think the field is not getting loaded here.

Any idea about the occurrence of this error?

Thanks in advance.

    The form will pass global context , not the formContext , so you will need to get formcontext before calling getAttribute method.

    formContext.getFormContext().getAttribute("new_fieldname");
     assuming 'formContext' is the name of the argument in your function.

    I have the exact same issue, did you find a solution to this? mine is  formContext.getAttribute(Applikata.Grade.Fields.Exam(true)).addOnChange(CalculateResult); and the field is alright in the form

    My recommendation - place it somewhere on the form and uncheck "Visible" checkbox in the properties - that should fix your issue.

    I have the field on header of the form and not anywhere else on form. However I am accessing it with 'new_fieldname' only (instead of header_new_fieldname). It works on one environment, form gets loaded properly. But, it fails on another environment (replica of the 1st environment) where I get above mentioned error.

    Can you confirm that field is available on the form? Without field available on the form getAttribute will return null so your code will fail.

    Hello Clofly,

    I have checked the field name and 'new_fieldname' is the logical name of the field.

    Hi Partner,

    You could check whether "new_fieldname" is actually the logical name of that field.

    I recommend to use Level up for Dynamics 365/Power Apps plugin of Chrome, after the plugin has been installed,

    click the "logical name" menu to get logical name of all fields of form quickly.
