Hi~ Another fix for review. https://issues.apache.org/ooo/show_bug.cgi?id=119941
Steps: 1. Open the .odt sample file (there is three charts created with data in table). 2. Focus on any chart, press Delete/Backspace to remove it, or press Ctrl+X to cut it. Issue: Application will crash. Root Cause: When cut or delete the chart, SwUndoFlyBase::DelFly will call SaveSection to store the comtent to strorage. In this step, chart filter functions will be called. And chart filter will call chart core functions to create the chart again. In the new chart2 base, chart core function will call a new class ExplicitCategoryProvider to create data source. In this step, when SW data source provider create the data source, it will create a new SwFlyFrm. But later in SwUndoFlyBase::DelFly, it will clear anchor related attributes of SwFlyFrm. Then finally null pointer occur. Solution: In pCnt->RemoveEmbeddedObject in SaveSection process for table chart, only remove the object from the object container, without removing it's storage and graphic stream. The chart already removed from formater.
