https://answers.axonivy.com/questions/2549/mechanism-to-resolve-data-and-logic-of-htmluserdialog<p>Hi ivyteam</p> <p>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.</p> <p>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 <em>Page A</em></p> <p><img alt="alt text" src="http://answers.axonivy.com/upfiles/Untitled_IZPJdpz.png"></p>enMon, 03 Apr 2017 18:07:36 -0400https://answers.axonivy.com/questions/2549/mechanism-to-resolve-data-and-logic-of-htmluserdialog/2563<p>Hi <a href="http://answers.axonivy.com/users/118/trungdv"><a href="http://answers.axonivy.com/users/118/trungdv">@trungdv</a></a></p> <p>Ivy needs to introduce custom <code>ELResolver</code> to handle resolving the <code>#{logic}</code> and <code>#{data}</code>. So you may want to start looking at the class <code>IvyLogicBeanResolver</code> and <code>IvyDataBeanResolver</code> and work out how Ivy integrate the expression with its <code>DialogRuntimeManager</code>.</p> <p>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.</p>Genzer HawkerMon, 03 Apr 2017 18:07:36 -0400https://answers.axonivy.com/questions/2549/mechanism-to-resolve-data-and-logic-of-htmluserdialog/2563
