Can not convert #BOOLEAN to a NodeList!

[klausT]

Hi,

For this xpath expression

Code: Select all

<xpath id="EtFsy">
      <dataBinding xpath="string-length(/Template[1]/SLD[1]/BusinessSystems[1]/BusinessSystem[1]/Products[1]/Product[1]/Vendor[1])&gt;0" storeItemID="{B981C26E-07CC-4E04-8DB5-6381C1213442}"/>
   </xpath>


I get the error message

Can not convert #BOOLEAN to a NodeList!

In your source code https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/openpackaging/parts/XmlPart.java at line 190 you are dealing with this kind of issue but it seems as string-length is not handled correctly.

Would be great if you could have a look at this.

Thanks,
Klaus

Hi Klaus

Is this system using docx4j v3.3.2, or something older? Did you get a stack trace?

I added the test case https://github.com/plutext/docx4j/commi ... c02df22ef8 but it seems OK already.

cheers .. Jason

Hi Jason,

We are using docx4j nighty build from 20161130.
So, not a really old version.

One challenge is that I can't reproduce the issue on my side.
But as one of our customers reports this issue there must be a dependency.
Maybe on the Java version, regional setttings, language...
The customer uses Java 1.8.0_74 whereas I use version 1.8.101. All on Windows 7, 64 Bit.

Here is the Stacktrace from the customer:

If it helps to reproduce the problem, I can also sent you the corresponding xml file plus the Docx template.

Turns out to be a language issue; Fixed by https://github.com/plutext/docx4j/commi ... df0b91d097

Will be in a nightly build later today.
