Hello

Have you try to check with the tracer ? You need first to verify if your OnChange rule is called and then if the onchange Activity is called. If none of those two rules are called then maybe you are updating the wrong property on the wrong class ?

Hi Marc,

　 

Thanks for your reply.

When i am tracing, i can able to see the declare on change updates. afer that there is no update on the case.

Example:

I had two fields like, First Name and Last Name, i have used these two in declare on change and i am  calling an activity which will concatenate the First Name and Last Name and map to Full Name.

　 

As per Declare on change, If i change first name and last name, full name should update automatically right.

But i don' t see any value on Full Name field.

Thanks,

Hi Chiranjeevi,

  Please check

1)Whenever you are changing the first name or last name ,could you able to see the acivity executing,which is concatenating the first name and last name.

2)If the activity executing,in your declare on change activity please check the page on which the activity is running and are the values exists in that page context.

3)Normally for this type of scenario ,go for declare expression where on the change of First name or Last name u can update the Full name by concatenating both of them by using the forward chaining.

No declaratives will fire from an activity whose security tab specifies that the activity is an "onchange" activity.

The intent is that you do your property-set in a different activity and that property-set should cause your "onchange" activity to fire, assuming your declare-on-change rule refers to it.  /Eric

Hi Osman,

　 

Thanks for ur replay,

　 

I had an requirement, like i had an section which is having different country hub numbers as text fields  [like Qatar Hub Number, Oman Hub Number] and Relation Country [Dropdown]. And i had another section in the same screen with field name called just hub number this is also text field.   

　 

Requirement: Whenever user select relation country as Qatar and if Qatar Hub Number has an value then Hub Number field should update immediatly with Qatar Hub Number.

　 

Please suggest me which Declare rule is best suitable and weather Declare-OnChage Will Works here or not?

For that, I don't think you need a declare-rule at all.  On the source field whose change should cause various target fields to change, in your design view, put in a behavior action that says "refresh section".  Then in your activity or data transform rule associated with the refresh action, set the target properties.  When the refresh is complete, you should see the updated target properties.

However, if are other places than the user editing the source field where such an update should occur, for example if there are places where you programmatically update the source property and expect the target properties to automatically update, then you may want to consider a declare-change or declare-expression rule.  If you do this, you still need your action that says to refresh the section when the user changes the source field, but you may not need to associate an activity or data transform rule with the refresh action, since your declare-change or declare-expression rule should kick in.  /Eric
