Hi,

You can try portal eventing for communication between iViews.

Hi Pankaj,

So, you can share this atributte value by using the interface controller! For example, when the atribute value be changed, this first component will send this new value to the others components!

I hope that this help!!

Hi ,Luciano

I understand that it has to go through this apporach only just tel me whether i am going correctly or not.

1) calling the inerface controller of second component from one of the view of the first component.

2)Then setting this value in the context of the interface controller , and then sending it to the component controller of the second component.

Pls help as its urgent.

Hi,

What you have done seems correct but I would say don't call the second component's interface controller directly from the view. Instead map values from the view context to the first component's interface controller context. Then in the interface controller have a method to pass values to the second component's interface controller. Call this method from the view.

Let the communication be only between interface controllers.

Hi Pankaj,

So, try to follow this way:

<b>1 - Event share attributes at View first component is fired</b> - The attribute is changed and the other components have to know this changes.

<b>2 - Method at first Component Controller is called</b> - This method is called by the View where the event that change the attribute values was changed. This statement will call the Interface controller of other components, and send the new value.

<b>3 - Method at each other's Interface Controller is called</b> - Each other's Interface Controller received the new value and set this new value at its Component Controller context.

This way will solve your problem!

Best Regards,

Luciano
