Issue with 2010 pptx containing shockwave flash object

[sma]

I've created a presentation in PowerPoint 2010 containing only one shoackwave flash object. I am trying to create a copy of this presentation using docx4j 2.8.0 API. The code runs successfully, but, when the copy presentation is opened, PowerPoint complains

"PowerPoint found a problem with the content in copy.pptx.
PowerPoint can attempt to repair the presentation."

When I say repair it says "This file cannot be opened by using Microsoft PowerPoint" and the presentation goes blank. This works absolutely fine for PowerPoint 2007. Any suggestions to get this working for 2010? Any help is greatly appreciated.

[jason]

How are you creating the copy?

When you run the original and the copy through PartsList, do they have the same parts?

Could you paste here the XML of the slide containing the flashobject, for the original and the copy?

[sma]

Thanks for getting back!
This is the piece of code I am using to create the copy

Code: Select all

String inputfilepath = "/home/sma/powerpoint/2010PPT.pptx";
String outputfilepath ="/home/sma/powerpoint/2010PPT_COPY.pptx";

PresentationMLPackage pmlPackage =(PresentationMLPackage)OpcPackage.load(new java.io.File(inputfilepath));

SaveToZipFile saver = new SaveToZipFile(pmlPackage);
saver.save(outputfilepath);

I've compared the parts and both presentations have 26 parts. Verified the part names, but couldn't find any difference. The XML of the slide in both the presentations are also the same. Copied them below for reference.

Please let me know if attaching both the presentations will be of any help. Many thanks!

[jason]

At a glance I'm surprised to see p14:creationId in the copy.

If you could email me the original pptx, I'll take a look. jason@plutext.org

This is from ECMA-376, first edition (as opposed to 2ed, which was not then available).

In the second edition, the model changed (pml.xsd) to:

So to fix we need to regenerate the pml classes using the second edition pml.xsd.

[sma]

Thanks Jason. I see that the fix is targeted for 2.8.1 release. Do you know of any rough timeline on when this would happen?

[jason]

August, unless I get some free time sooner.

[sma]

The issue still exists with the 2.8.1 version also. Looks like it hasn't been addressed. Would like to know if there is any update on when it is likely to be resolved? I am waiting eagerly for it. Any input is greatly appreciated.

[jason]

Yes, sorry, I overlooked this.

I'll aim to look at it in the first week of November. It wouldn't hurt to remind me on 1 November...

cheers .. Jason

[sma]

The reminder that you've asked for! Many thanks in advance.

[jason]

Thanks for the reminder.

Issue 13 now closed.

You can fetch the code from GitHub now, but I will also create a nightly incorporating the changes a bit later today.

[sma]

Thanks Jason, but, I still can't get it working. When I tried the nightly build "docx4j-nightly-20121104.jar" the code runs successfully but the issue with creating a copy of 2010 presentations still exists.
With the nightly build "docx4j-nightly-MOXy-20121106.jar", the code throws an exception complaining of "java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory" Tried to add a new dependency jar "easybeans-uberjar-eclipselink-1.1.0-M1.jar" but still it was giving a different exception.
Can you please help?

Many thanks
sma

[jason]

Please try http://www.docx4java.org/docx4j/docx4j- ... 121108.jar

If that doesn't work, then please attach a 2010 pptx with a flash object added in Powerpoint, and I'll see whether I can round trip it.

[sma]

Opening the copy is giving the message "Some controls on this presentation can't be activated. They might not be registered on this computer."
I see one warning message on the console
WARN JaxbValidationEventHandler:90 - [ERROR] : unexpected element (uri:"http://schemas.openxmlformats.org/markup-compatibility/2006", local:"AlternateContent"). Expect

src/main/java/org/docx4j/jaxb/mc-preprocessor.xslt selects the mc:Fallback content. With this pptx, using this yields the message you saw when I try to open it
in powerpoint 2010. But it works in 2013 preview!

I tried using the mc:choice content; powerpoint 2010 said it "found a problem with content" .... Same problem with the 2013 preview.

So it looks like the mc:AlternateContent mechanism is not working as advertised in Powerpoint 2010, and only partially working in 2013.

I think we might need to seek some input on the MSDN forums.

[jason]

I have an idea for a workaround for this probable problem with mc:AlternateContent in Powerpoint 2010; give me a few days to try it out.

[sma]

That sounds great! Please keep me posted!!

[jason]

With https://github.com/plutext/docx4j/commi ... 2431d34618 mc:AlternateContent in a pptx slide's p:controls is preserved.

However, Powerpoint still doesn't like round tripped output from flash.pptx!

I have no idea why, having spent an hour or 2 looking at it.

Maybe somebody else can find what Powerpoint is complaining about.

The fact that there is still a problem when the mc:AlternateContent element is preserved, suggests that the actual problem is elsewhere (and therefore that we might not need to preserve it after all).

[jason]

Fixed!

https://github.com/plutext/docx4j/commi ... b47765e718

[sma]

I was overjoyed to see an update here! But with the jar "docx4j-nightly-20130425.jar" I can't get it working for either 2007 or 2010. No errors in the process, but powerpoint cannot the open the copy. It is giving the message "Powerpoint was unable to display some of the text, images, or objects on slides in file..., because they have become corrupted." is there anything I am missing?

[jason]

Since that was a few days ago, I'm not certain whether I made the fix then the jar, or made the jar first (and the fix later in the day), but it is likely the fix is in that jar.

I confirmed the fix by running your pptx 2010_PPTX.pptx through org.pptx4j.samples.RoundTripTest and opening the output in Powerpoint 2010.

Did you do that, or something different?

[sma]

Many thanks Jason!! It works great with org.pptx4j.samples.RoundTripTest!!!
I was trying to save using the org.docx4j.openpackaging.io.SaveToZipFile and that is failing.

Code: Select all

SaveToZipFile saver = new SaveToZipFile(presentationMLPackage);
saver.save(outputfilepath);

I prefer 'SaveToZipFile' as the save method there can take java.io.OutputStream as its parameter and not restricted just to java.io.File.
Any chance you can update SaveToZipFile or do you recommend using the save on org.docx4j.openpackaging.packages.PresentationMLPackage?
