Mechanism to resolve data and logic of HtmlUserDialog

Hi ivyteam

As you know in HtlmUserDialog we can use #{data} or #{logic} to access the attribute/method on ivy from view(xhtml). No matter which component/page you have, you can use #{data} and #{logic} anywhere and it always work in correct context, There is no mistake that you use #{data} from component A but it return data of component B. That's great.

So i have two questions: - Can you share the mechanism how did you resolve those keywords in ivy (ex: some class that i can explore by myself), i guess that there is a managed bean(view scope) behind the scene? - If i have the page with some components as below picture, can i access #{data} of any components i want programmatically? I tried to resolve EL #{data} after the page has been loaded and it always return data of Page A

Do you want to access #{data} from Component A within Page A? Or vice versa? Or both? And this also for #{logic}?

Hi @trungdv

Ivy needs to introduce custom ELResolver to handle resolving the #{logic} and #{data}. So you may want to start looking at the class IvyLogicBeanResolver and IvyDataBeanResolver and work out how Ivy integrate the expression with its DialogRuntimeManager.

But I think they are not part of the public API, so any code relying on these class are subject to be changed from release to release. So be careful then.
