https://answers.axonivy.com/questions/1326/mapping-data-of-parent-jsf-dialog-get-data-back-from-child-component<p>Hi, I have a scenario like this: I build an Ivy component for user selection(Autocomplete). Then after select a user, parent dialog should receive the selected IUser object.</p> <p>My current solution :</p> <p>Parent dialog : <img alt="alt text" src="http://answers.axonivy.com/upfiles/parent_dialog_1.png"> Dataclass <strong>UserData</strong> <img alt="alt text" src="http://answers.axonivy.com/upfiles/userData.png"> Child Component <img alt="alt text" src="http://answers.axonivy.com/upfiles/child_component_1.png"> Mapping data in startLink <img alt="alt text" src="http://answers.axonivy.com/upfiles/Mapping.png"></p> <p>With this solution, I can get the selected <strong>IUser</strong> via object <strong>userData</strong>. Because I think in this case, 2 variables point to the same memory, so parent dialog can get the updated data when it change on child component.</p> <p>But I have a requirement to make it more flexible, do not use object <strong>userData</strong>. User UserName or IUser for input parameter.Like this Parent dialog : <img alt="alt text" src="http://answers.axonivy.com/upfiles/Parent_dialog_2.png"></p> <p>But when I try to mapping like my current solution. Parent dialog can not get the selected data from child component. I think because <strong>UserName</strong> is a string, and it will create a new object when we change it. For IUser, it's an Interface.</p> <p>So if anybody has experience to solve it. Please help me.</p> <p>Thank you and regards.</p>enFri, 29 May 2015 09:55:56 -0400https://answers.axonivy.com/questions/1326/mapping-data-of-parent-jsf-dialog-get-data-back-from-child-component/1343<p>Another approach could be, to simply map output arguments for the start method of the component.</p> <p>So, define an output argument in the interface of the component of type IUser. And then, inscribe the result mapping in user dialog start event of the component.</p> <p>This works but has one bigger issue: The result mapping is done <strong>after</strong> parent dialog is rendered. So you will see values which are not up to date there (respectively with a delay of one time refresh) even though the data is correct. But have a look at it anyway.</p>Dominik RegliFri, 29 May 2015 09:55:56 -0400https://answers.axonivy.com/questions/1326/mapping-data-of-parent-jsf-dialog-get-data-back-from-child-component/1343https://answers.axonivy.com/questions/1326/mapping-data-of-parent-jsf-dialog-get-data-back-from-child-component/1342<p>Maybe it's a solution for you to work with a callback method? </p> <p>You can get more details about it, in the HtmlDialogDemos project -&gt; Component Callback Demo (Component/ComponentEventListenerDemo.ivp).</p>Dominik RegliFri, 29 May 2015 09:54:41 -0400https://answers.axonivy.com/questions/1326/mapping-data-of-parent-jsf-dialog-get-data-back-from-child-component/1342
