[JBoss Seam] - Select item from table and convertEntity
by brachie
Hi,
I have a use case to implement which could normally done with a <h:selectOneMenu> and <s:convertEntity />.
Imagine you have a project editing page where I can set the manager of a project. Normally this could be done with a drop-down list like:
<h:selectOneMenu value="#{project.manager}">
| <s:convertEntity />
| <s:selectItems value="#{allPersons.resultList}"
| var="person"
| label="#{person.name}"/>
| </h:selectOneMenu>
So the <s:converEntity/> will automatically converts the selected person and set it to my project (project hast a setManager(Person p) method).
But what if the data-list (here: allPersons.resultList) is too big to show it in the drop-down list? Let's say the list has 100000 entries.. In this case a popup should appear where I can search for persons, see the results in a table where I can select one to set for the project.
How could I accomplish that? Is there a way to use the <s:convertEntity> here or would I need to grab the id of the selected person manually and set it to the entity before saving it?
I think this is a common use case in real-world applications, so maybe one of you can give me a hint on how to implement it with Seam/JSF possibilities.
Thanks,
Alexander
