'''Answer:''' The old API has methods getTitle()/setTitle() as well as the new API. So, you have to switch to the new API here. Note, that the new API is not published yet. You should wait until we have resolved this ambiguity! We have to fix this ambiguity, as there are two methods with the same name and different return types at one object.

'''Answer:''' Get a newer version. In OOG680.m2 the new API has changed. The interface XTitled now has the methods getTitleObject and setTitleObject. Thus the name-clash that lead to this problem no longer exists from that version on. (OOG680.m2 is a pre-release of OOo2.3)

If you have written StarBasic Macros or other Code that uses the API in com.sun.star.chart and want to be able to still run it with the new chart here is some help in case you encounter problems. If you have problems not listed here feel free to add them here.

Note, that the new API is not published yet, so you should not use the new API extensively before it is published!

Using StarBasic Macros

Question: I can no longer set the main title using the Title property.

 ' oMyChart is the XChartDocument (XModel)
 oMyChart.Title = "My Title"

Answer: Get a newer version. In OOG680.m2 the new API has changed. The interface XTitled now has the methods getTitleObject and setTitleObject. Thus the name-clash that lead to this problem no longer exists from that version on. (OOG680.m2 is a pre-release of OOo2.3)
