TreeView crashes

General JUCE discussion

Happen in develop,
add to the ValueTreeDemo file

class ValueTreeItemComponent : public Component
{
public:
  ValueTreeItemComponent(TreeViewItem *pItem)
  : label("coucou")
  {
    addAndMakeVisible(&label);
  }
  
  ~ValueTreeItemComponent()
  {
  }
  
  void resized() override
  {
    label.setBounds(0, 0, getWidth(), getHeight());
  }
  
  juce::Label label;
};

and to ValueTreeItem

std::unique_ptr<juce::Component> createItemComponent() override
    {
        return std::make_unique<ValueTreeItemComponent>(this);
    }

and replace ValueTreeDemo::timerCallback impl by

void timerCallback() override
{
    undoManager.beginNewTransaction();
  
  rootItem->clearSubItems();
  rootItem->refreshSubItems();
}

click some item and at some point…boom :slight_smile:

Here is the full file
ValueTreesDemo.h (10.3 KB)

Thanks !
