Hi there,
i have a problem which is related to my custom activity in .net Workflow 4.
My custom activity XActivity can hold other activities. Everything works fine even the displaying and executing.
Except when i doublecklick on a custom activity for getting the detail view (expanding). Then the activity which is a child activity will be executed more than one time. In fact every time i click on expand the number of execution times will be doubled or something like this.
<sad:WorkflowItemsPresenter Name="myWorkflowElements" Grid.Row="1" Items="{Binding Path=ModelItem.ChildActivities}" Drop="WorkflowItemsPresenter_Drop">
<sad:WorkflowItemsPresenter.SpacerTemplate>
<DataTemplate>
<TextBlock Width="150" Height="20" Text="Drop xxx Here" Foreground="Gray" />
</DataTemplate>
</sad:WorkflowItemsPresenter.SpacerTemplate>
<sad:WorkflowItemsPresenter.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" Margin="16"/>
</ItemsPanelTemplate>
</sad:WorkflowItemsPresenter.ItemsPanel>
</sad:WorkflowItemsPresenter>
I dont know what is wrong there.
Perhaps there is something wrong with the connection to the activity.
