What is wrong with following event ajax call ffrom form on chanhe od date field

Hi Eduardo,
you only add rules at load and on change on date2. I have copy your JS function in my environment and no meter what date I select count duration is always 1. Should I do something else maybe I need to add more JS rules on the form.
And it need to be trigger on any change of From Date and To Date even the first one from nothing to date.
Best Regards, Natasa

The field_id for duration is changed because I add and remove this field.

I even try and import your form in one simple process with only user input task and test it the result is the same no meter what date I select duration is 1.Just to confirm that form that use is not so special, als JS file that I call is that has function for validation of to date not be selected before from date (Negative duration)

Good catch. This type of issues can be easily diagnosed using Fiddler to monitor the request you are doing. If you take a look at the request: http://<SERVER>/suite/plugins/servlet/forms_expression in Fiddler you will see the expression is sent as: expression%3D%3Dcalworkdays(2%2F1%2F2012%2C2%2F7%2F2012) which can be decoded using this site: meyerweb.com/.../ When decoded you will see the expression we are evaluating is of type:expression==calworkdays(2/1/2012,2/7/2012) which is not correct, because there are no quotes surrounding the dates. If you test this directly in the Rules interface it will give you the wrong value too.

The solution is changing the JS to make sure the dates are enclosed in quotes:

FormAPI.evaluateServerSideExpression(function(e){debugger; window.FormAPI.setValue('number41',e);},'=calworkdays("' + FormAPI.getValue('date1').id + '","' + FormAPI.getValue('date2').id +'")');

Here's the updated example (exported form): forum.appian.com/.../36837

After this change Fiddler will show the right expression in the request: expression=%3Dcalworkdays(%222%2F1%2F2012%22%2C%222%2F7%2F2012%22) which decoded looks like this: expression==calworkdays("2/1/2012","2/7/2012") with the parameters in quotes.

HI eduardo
How i can set 3 fields with the given JS code.
Suppose i have number41,number42,number43 fields...


FormAPI.evaluateServerSideExpression(function(e){window.FormAPI.setValue("number41",e);},
"=calworkdays(" + FormAPI.getValue("date1").id + "," + FormAPI.getValue("date2").id +")");

If the result of your calworkdays expression is supposed to be used to set number41, number42, number43 just add the corresponding setValues after window.FormAPI.setValue("number41",e); separating each statement with a semicolon for instance:

FormAPI.evaluateServerSideExpression(function(e){window.FormAPI.setValue("number41",e);window.FormAPI.setValue("number42",e);window.FormAPI.setValue("number43",e);},
"=calworkdays(" + FormAPI.getValue("date1").id + "," + FormAPI.getValue("date2").id +")");
