Using Editor Framework with GWTP

[Arpit Tripathi]

I'm always confused about GWTP and Editor framework. In general I use the recommendation from this blog: http://floonit.blogspot.com/2012/07/gwtp-and-editors.html

I'm confused what will be used as editor in this case:

Form 1 edits an Entity X and includes Form 2 (PresenterWidget) which edits X.Address. To edit X.Address, Form2 uses some other PresenterWidget (w1) which edits locations using TexBox.

When w1's textbox is empty, I want to show ConstraintViolation error using a label in form2 (since w1 doesn't know anything about editors). I don't know which editor hierarchy to follow so that driver.setConstraintViolations(...) automatically sets errorLabel for field 'Address' in form2. 

Suggestions?

Thanks.

You don't need any PresenterWidgets, just editors. Have Form1Editor as your main one, then have Form2Editor as a sub-editor of that. As long as you have the correct getters and setters it should descend correctly. You can pass events around via the eventBus, or go for a ValueAwareEditor which can monitor its children.

If you post some actual code we might be able to help you more.
