OnlyOffice - w:sdtPr/w:label - unexpected element error #586

Closed maddin79 closed 2 months ago

maddin79 commented 2 months ago

Hello everyone,

I hope someone can help me with this issue. I can not find any solution to it.

OnlyOffice version: 8.1.0.169 Java version: JDK 21.0.2 docx4j-JAXB-MOXy version: 11.4.11 (The error is the same with other docx4j jaxb implementations)

I'm creating a docx document with OnlyOffice that contains content control field. Here is a simple example of the document.xml:

The problematic line is <w:label w:val="0" /> in <w:sdtPr>.

The java code looks like: 

File doc = new File("/home/mdrees/Documents/Privat/test-doc3.docx");
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(doc);
MainDocumentPart mainDocumentPart = wordMLPackage.getMainDocumentPart();
SdtFinder sdtFinder = new SdtFinder();
org.docx4j.wml.Body  documentBody = mainDocumentPart.getJaxbElement().getBody();

The error happens on the last line with the follow stack trace:

java.lang.NullPointerException: Cannot invoke "org.docx4j.wml.Document.getBody()" because the return value of "org.docx4j.openpackaging.parts.WordprocessingML.MainDocumentPart.getJaxbElement()" is null

According to the documentation about open xml format, the label is allowed on that position. How can I fix this issue? I quite new to docx4j.

Best Martin

w:label is not supported in https://github.com/plutext/docx4j/blob/VERSION_11_4_12/docx4j-openxml-objects/src/main/java/org/docx4j/wml/SdtPr.java

You could add it in there manually, and in https://github.com/plutext/docx4j/blob/VERSION_11_4_12/docx4j-openxml-objects/src/main/java/org/docx4j/wml/ObjectFactory.java

(Normally we'd do that by providing for it in the xsd, then regenerating the code using xjc, but manually editing works fine as well)

Or if w:label serves no purpose, you could remove it from your document using https://github.com/plutext/docx4j/blob/VERSION_11_4_12/docx4j-samples-resources/src/main/resources/custom-preprocessor.xslt

docx4j uses ECMA-376, first edition (as opposed to 2ed, which was not then available) plus various amendments. It seems that label is defined in §17.5.2.19 of [ISO/IEC 29500-1 1st Edition] according to https://learn.microsoft.com/en-us/dotnet/api/documentformat.openxml.wordprocessing.sdtproperties?view=openxml-3.0.1 but afaik Microsoft Word doesn't write it.

Hello @plutext,

thank you very much for the hints. The label field has indeed no purpose for me. I don't know why OnlyOffice adds it. I create the fields with an plugin and the API of OnlyOffice. The weird thing is, if I add a field into a table, the label is not there, but the code for the field is the same.

I check out the preprocessor. Looks promising.

maddin79 commented 2 months ago

I added in src/main/java/resources the docx4j.properties and the custom-preprocessor.xslt in my maven project. But I looks like they are not taken into account. I also can not find documentation about this feature nor how to customize the preprocessor. How does it work and how do I remove the field from the document?

plutext commented 2 months ago

Do you have a line like https://github.com/plutext/docx4j/blob/VERSION_11_4_12/docx4j-core/pom.xml#L192 in your pom.xml

To your custom-preprocessor.xslt you need to add the line: 

<xsl:template match="w:label" />

If the mechanism is working, it will be invoked from https://github.com/plutext/docx4j/blob/VERSION_11_4_12/docx4j-core/src/main/java/org/docx4j/openpackaging/parts/JaxbXmlPartXPathAware.java#L574

maddin79 commented 2 months ago

Hi @plutext,

I added the resource line and I also had the w:label in the xslt. But the ouput does not change. I run this with Intellij and also build an executable jar with all dependencies. The xslt is not taking into account at all. No idea what I'm doing wrong.

plutext commented 2 months ago

Seems like you have logging configured; so you have some resources being read? Configure it for INFO level logging; do you see the log at line 574 above? If you still can't get it working, you could create a small test case maven project and I will look at it for you.

maddin79 commented 2 months ago

Sorry for the late reply. I did some debugging and found the setting

String transformParts = Docx4jProperties.getProperty("docx4j.jaxb.preprocess.always");
        boolean transformFirst = (transformParts!=null 
                && transformParts.contains(this.getClass().getSimpleName()));

and put 

docx4j.jaxb.preprocess.always=MainDocumentPart

in the docx4j.properties. Works perfectly. I did not find the root cause why the xslt is not taken into account, when the unmarshaling fails.

Thanks for the help. For me it is fixed. I think to preprocess the file always is in my case better anyway. The documents will always come from OnlyOffice.
