Accessing Uibinders DOM element in View and Presenter

[Jose]

Hi All,

 

I have input, div, span, select elements in my uibinders file. How can I access those elements in view and presenter class.

 

So that, I can convert into TextBx.wrap(Element element) and attach handlers to it for validation.

 

I tried, using DOM.getElementById() in onBind() it returns null, because DOM is not attached yet and I tried it in onReveal it returns the Element, but not able to use TextBx.wrap(Element element);

 

it throws

 

java.lang.AssertionError: A widget that has an existing parent widget may not be added to the detach list    

at com.google.gwt.user.client.ui.RootPanel.detachOnWindowClose(RootPanel.java:136)    

at com.google.gwt.user.client.ui.TextBox.wrap(TextBox.java:69)

 

I tried to access in View class constructor, No use.

 

right place to get the DOM element?

 

Please help me,

 

Thanks In Advance,

Bennet.

I think the error message is telling you what the problem is - the element already has a parent widget (the uibinder widget, perhaps).  But if you want access to the element using a widget - why not just create the widget you want in the UIBinder?  That would avoid the whole problem
