Description Laurent Balland 2024-04-06 13:03:30 UTC
Description:
When opening a file containing an embedded chart, there is a warning message:
warn:xmloff:1302942:1302942:xmloff/source/chart/SchXMLChartContext.cxx:392: unknown attribute http://www.w3.org/1999/xlink xlink:type value=simple
content.xml contains xlink:type="simple":
<draw:object xlink:href="./Object 1" xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad">
which appears to be valid in ODF [1]

Steps to Reproduce:
1. Create a new empty presentation
2. Insert a default chart via Insert > Chart
3. Save as ODP
4. File > Reload

Actual Results:
A warning message is displayed in the console:
warn:xmloff:1302942:1302942:xmloff/source/chart/SchXMLChartContext.cxx:392: unknown attribute http://www.w3.org/1999/xlink xlink:type value=simple

Expected Results:
No warning message


Reproducible: Always


User Profile Reset: No

Additional Info:
It seems that SchXMLChartContext::startFastElement [2] is missing
case XML_ELEMENT( XLINK, XML_TYPE )
like in ScXMLCellFieldURLContext::startFastElement [3]

Comment 1 Laurent Balland 2024-04-06 13:05:28 UTC
If saved as FODP, attribute xlink:type is inserted in chart:chart node
Comment 2 Laurent Balland 2024-04-08 11:23:04 UTC
@Regina: any though about this report?
I prepared this commit, in case you agree:

Comment 3 Regina Henschel 2024-04-08 13:06:59 UTC
I think you are right, the attribute xlink:type is allowed in <chart:chart> element. But it is grouped with the xlink:href attribute. This group is optional, but when it exists, both attributes have to be present.
