I’m not sure if i’m doing something wrong. In my TreeGrid i want to enable editing the root elements with a simple TextField.
I’ve added a EditorComponent to one column and a method which is called after saving the value. Although the sample code is not pure java, it’s hopefully understandable:
treeGrid.addColumn([s | s.name]
)
.setCaption("name")
.setId("NAME")
.setEditorComponent(new TextField(), [ MyBean s, String b | s.name = b; /* some more code */]
)
.editable = true
In the commented code place /* some more code */ i have played with
treeGrid.dataProvider.refreshItem(s)
treeGrid.dataProvider.refreshAll
in every combination - but without success.
To explain what’s happening i’ve attached some screenshots.
Image 1: The intial tree
Image 2: Double-Click on “Root 1”. The TextField is shown and i changed the string value and click save.
Image 3: The root element was renamed, but lost all children
And after this, i tried to expand/collapse “Root 2” and got the exception. Which duplicate key?
java.lang.IllegalStateException: Duplicate key MyBean [
name = "Root 1 New"
]

Hopefully someone can help on this topic. Otherwise i have to discard the inline editing of the elements.
