Hi,

I am trying to enter edit mode after the node is created using a behavior. However it comes out of the edit mode automatically. Please help where I'm doing wrong. 

Code for xaml and behavior:

xaml:

<ig:XamDataTree
ItemsSource="{Binding Path=ProjectCollection}"
ActiveDataItem="{Binding ActiveNode, Mode=TwoWay}"
AutomationProperties.AutomationId="aid_ProjectExplorerTree">

<ig:XamDataTree.EditingSettings>
<ig:TreeEditingSettings AllowEditing="True" AllowDeletion="False" IsEnterKeyEditingEnabled="False" IsF2EditingEnabled="True" IsOnNodeActiveEditingEnabled="False" />
</ig:XamDataTree.EditingSettings>

<ig:XamDataTree.SelectionSettings>
<ig:TreeSelectionSettings NodeSelection="Single" />
</ig:XamDataTree.SelectionSettings>

<ig:XamDataTree.InputBindings>
<KeyBinding Key="Delete" Command="{Binding EditManager.DeleteCommand}" />
<KeyBinding Gesture="Ctrl+D" Command="{Binding EditManager.DuplicateCommand}"/>
<KeyBinding Key="F4" Command="{Binding EditManager.PropertiesCommand}"/>
</ig:XamDataTree.InputBindings>

<i:Interaction.Behaviors>
<behaviors:XamDataTreeCommonBehavior />
<workbench:TreeNodeEditBehavior />
</i:Interaction.Behaviors>

<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseDoubleClick">
<i:InvokeCommandAction Command="{Binding EditManager.OpenCommand}">
<i:InvokeCommandAction.CommandParameter>
<MultiBinding Converter="{StaticResource CapabilityParameterConverter}">
<Binding Source="{StaticResource BindingProxy}" Path="Data.Project"/>
<Binding Source="{StaticResource BindingProxy}" Path="Data.ActiveNode"/>
</MultiBinding>
</i:InvokeCommandAction.CommandParameter>
</i:InvokeCommandAction>
</i:EventTrigger>
</i:Interaction.Triggers>
