Bug 131979

Created attachment 159409 [details]
Example file from Calc

In Calc when a chart is added and data labels are turned on, they by default get the Source Format setting turned on. However if this is turned off for a certain data point, this setting is not saved to the file, leading to the custom format being reset when the Format Number dialog is opened.


Steps to reproduce:
1.	In Calc add some numbers to cells. Create a simple bar chart from them.
2.	Edit the chart, turn on Data Labels for the data series.
3.	Edit one data point, press the Data Labels tab – Number format button
4.	In the Number Format dialog uncheck the Source Format box and select some number format, such as Scientific
5.	Save the file as ODS and reopen

Actual results:
When the file is opened in current master the scientific formatting is lost. In 6.3 it was lost only when the Label for Data Series dialog was opened.

Expected results:
Custom number format retained when Label for Data Series dialog is opened and closed without changing anything.
