Property 'selectedItems' not writable on type org.zkoss.zul.Tree
... on the following zul...
<tree
model="@load(vm.categories)" checkmark="true"
multiple="true" width="100%" vflex="true" selectedItems="@bind(vm.selectedCategories)">
<treecols>
<treecol
label="" />
</treecols>
<template name="model"
var="c">
<treeitem
checkable="@load(c.data.selectable)"
selected="@load(c.data.selected)" >
<treerow>
<treecell
label="@load(c.data.title)" />
</treerow>
</treeitem>
</template>
</tree>
... with the following mvvm class...
public abstract class AbstractAllResourcePricesListVM extends AbstractDataViewVM implements PageListModelErrorHandler {
@WireVariable
protected ResourcePriceManager resourcePriceManager;
@WireVariable
protected ResourceCategoryManager resourceCategoryManager;
private AllResourcePricesPageListModel fPrices;
private ResultSetOrder fResultSetOrder;
private SearchCriteria fSearchCriteria;
private DefaultTreeModel<DefaultTreeNode<SelectableTitledDO>> fCategories;
private Set<SelectableTitledDO> fSelectedCategories;
**
Any suggestions?
Looking at the Tree Java API it seems to be missing a 'setSelectedItems' method, even though its has 'getSelectedItems' .
I solved the problem by passing 'getSelectedItems as a @command parameter to the button onClick method that confirms the selections

Indeed, whats wrong with mine answer : You have to implement correct getters and setters in your MVVM? Vote for correct answer and not your own solution.

fSelectedCategories in MVVM and selectedCategories in zul.
And :
private DefaultTreeModel<defaulttreenode<selectabletitleddo>> fCategories; <==> model="@load(vm.categories)"
This could be wrong(I'm not 100% sure of that) : abstract class as viewmodel?
Greetz chill.
Thats not wrong by taking the f off the getter and setter, but you do an @bind, so you need a getter AND a setter otherwise it will be @load only. (answer you talk no setter and comment you have one?)
chillworld ( 2013-11-26 12:25:47 +0800 )editYou might return a null tree model in VM, and causes zkbind can't set the selection to model(null), instead it set selection directly by 'setSelectedItems', however there is not such API in Tree, so you get [Property 'selectedItems' not writable on type org.zkoss.zul.Tree]

I've tried this another way, by putting bindings on both the tree model and the tree item 'selected' property and in both cases the binding is NOT updating the underlying model.
