setvalid

I have an item X which can take two values on or off. depending on the value , i want items y and z to be activated/deactivated.

When x is on y is not filled in, hence any validation on the fields in item y should be skipped. the same applies when x is off for z. Hence when x is on, i am setting the item y as valid always so that the fields of item y need not be filled and the same applies for z when x is off.
The code used is given below

IWEventRegistry.addItemHandler("/cont/x",
"onItemChange", SelectObject);

function SelectObject() {

var typeItem=IWDatacapture.getItem("/cont/x");
var flag = typeItem.getOptions()[typeItem.getValue()].value == "on";
if(flag)
{
IWDatacapture.getItem("/cont/y").setValid(true);
}
else
{
IWDatacapture.getItem("/cont/z").setValid(true);
}

}

This is not working, irrespective of whether x is on or off, save is not possible without fulfilling all the validation on fields of y and z. any suggestions?

thanks

You are assigning and checking for the equality fo values within one statement. Either extract the value of your item within flag variable OR check for the equality in your if clause.

var flag = typeItem.getOptions()[typeItem.getValue()].value;
if(flag == "on")

The statement(assignment and comparison) works fine. i tried to make the y/z items invisible depending on value of x within the function and that worked. However, Is the usage of setvalid appropriate and correct here? Is there any alternative to completely remove the y/z item depending on value of x?

Hi,

you can try with the y/z items IWDatacapture.getItem("/cont/y/z").setValid(true/false); to be set to true and the other item as false at both the places in the if ......else part .
Hope it should work then.

Thanks,
Pawan

Are the items y/z are the items with in a container or replicant? Also mention the environment you are working on?

First of all, you can simplify your code because the item is passed to the event handler. Secondly, you are presumably dealing with required vs. non-required fields as well as valid vs. non-valid - so I think you need to beef up the conditional within your function - something like this:

function SelectObject(item) {     
      var flag = (item.getOptions()[item.getValue()].value == "on");
       if(flag) { // x is on     
              IWDatacapture.getItem("/cont/y").setValid(true);               
IWDatacapture.getItem("/cont/y").setRequired(false);               
IWDatacapture.getItem("/cont/y").setVisible(false);               
IWDatacapture.getItem("/cont/z").setRequired(true);               
IWDatacapture.getItem("/cont/z").setVisible(true);               
       }
       else { // x is off
              IWDatacapture.getItem("/cont/z").setValid(true);                       
IWDatacapture.getItem("/cont/z").setRequired(false);               
IWDatacapture.getItem("/cont/z").setVisible(false);               
IWDatacapture.getItem("/cont/y").setRequired(true);               
IWDatacapture.getItem("/cont/y").setVisible(true);               
       }                              

}

Or you can break it up into additional functions like:

 function SelectObject(item) {     
      var flag = (item.getOptions()[item.getValue()].value == "on");
       var y_item = IWDatacapture.getItem("/cont/y");
       var z_item = IWDatacapture.getItem("/cont/z");
       if(flag) { // x is on
disable(y_item);
              enable(z_item);
       }
       else { // x is off      
disable(z_item);
              enable(y_item);
       }
}
function disable(item){
    item.setValid(true);
    item.setRequired(false);
    item.setVisible(false);
}
function enable(item){
    item.setRequired(true);
    item.setVisible(true);
}

y and z are containers within a container. in the example given, cont is the parent container and y and z are containers within cont.

thanks for the replies. why is item.setRequired(false) necessary for the invisible item? item.setValid(true) makes sure that the item is valid whether the required fields are filled in or not and hence skips the validation tests during save for the invisible item, is that right?

Vid

Oh Or reading your replies more carefully, i understand that validations on a field and a required field are two different things. ie "a required field" is not a validation criteria ?
y is a replicant. cont/y[1]/(required field item).setRequired(false) sets the required field for the first instances as false. however, how can i find the number of instances that are present in the DCT. ie say the user selects y( x= off), fills in 2/3 instances and switches back to x=on. In this case required fiedls for instances 2 and 3 are not false. any suggestions?

thanks for your time and patience.

Did you get the results?

Vid

yes

but not in the case of replicant. .

wild123

yes but not in the case of replicant. .

You might want to use
IWDatacapture.getItem("/cont/y").getChildren().length .
Please go through the formsAPI PDF to know more.

I think the flaw here is in your form design. You cannot have a controlling item outside the context of the controlled items and expect it to work in all cases unless you expect to have identical structures (number of instances) for three separate items - which sounds like a horrible UI as well as a questionable design.

What is the actual association between 'x', 'y', and 'z'

My assumption was that for any instance of x there is either an instance of y or an instance of z. If multiple instances of y and z are allowed, then for each instance of x there should be 1-or-more instances of y or z (but not both).You seem to be indicating that there is one instance of x and multiple instances of y and z which are being controlled by x in an arbitrary fashion.

Vid

For an instance of x (there is only one), there is either an instance of y or an instance of z. multiple instances of y are allowed (y is a replicant), there can be only one instance of z( z is a container).

if the user selects 2/3 instances of y, and then changes his mind n chooses z, i have to (remove/invalidate) all instances of y. Yes, getting the length(number of instances of y) is a possible solution.

What do you mean by the user's using 2/3 instances of Y? I guess that you need to understand that 2/3 = (2+1)/3 ,here. I am saying so because if the user doesnt need the 1/3 instance he should delete it from the replicants iterated list but because the user has left it undeleted ,he might be willing to use it along with the other 2/3 .So the code mentioned earlier in the thread along with the help of GetChildren() will help you achieve the functionality.

We are calculating the no. of items ,using GetChildren(),here because we have to create an array which holds the items in the replicant and then have to pass the array elements to the disable and enable functions(as mentioned earlier) through function call.

Any more doubts?
