Exception when merging documents

[HarryVienna]

Hello!

We use your enterprise extension for procesing special Word documents.

One task ist to merge another document in the main document. This worked so far very well. Now i got a new main document and this time a get an exception when I include the same other document. The main document has many content controls (SdtBlock elements) in it, and one of these content controls is the marker where to insert the other document.

I have no idea, what the problem could be
Here is the exception:

13:28:25.917 [main] INFO com.plutext.merge.DocumentBuilder -

13:28:26.088 [main] ERROR com.plutext.merge.DocumentBuilder - org.docx4j.wml.SdtBlock cannot be cast to org.docx4j.wml.ContentAccessor

This is my source where the exception occours:

Thanks for you help. Do you need sample documents ?

Perhaps this can be the reason:

This is the XML part of the document that works:

Code: Select all

<w:bookmarkStart w:id="27" w:name="_GoBack" w:displacedByCustomXml="next"/>
      <w:sdt>
         <w:sdtPr>
            <w:alias w:val="Text_Fondsbestimmungen"/>
            <w:tag w:val="include"/>
            <w:id w:val="-84386685"/>
            <w:placeholder>
               <w:docPart w:val="DefaultPlaceholder_1082065158"/>
            </w:placeholder>
         </w:sdtPr>
         <w:sdtEndPr/>
         <w:sdtContent>
            <w:p w:rsidR="00EA6113" w:rsidRDefault="00C562E7">
               <w:pPr>
                  <w:spacing w:line="240" w:lineRule="auto"/>
               </w:pPr>
               <w:r>
                  <w:t>Fondsbestimmungen</w:t>
               </w:r>
            </w:p>
         </w:sdtContent>
      </w:sdt>
      <w:bookmarkEnd w:id="27" w:displacedByCustomXml="prev"/>

And here the document that does not work:

Code: Select all

<w:bookmarkStart w:id="70" w:name="_Toc418591205" w:displacedByCustomXml="next"/>
      <w:sdt>
         <w:sdtPr>
            <w:alias w:val="Überschrift_Anhang"/>
            <w:tag w:val="Text"/>
            <w:id w:val="-147053134"/>
            <w:placeholder>
               <w:docPart w:val="DFFE9A984BDE4D3080AA6E6611A0DFE8"/>
            </w:placeholder>
         </w:sdtPr>
         <w:sdtContent>
            <w:p w:rsidR="007D5DAD" w:rsidRDefault="007D5DAD" w:rsidP="007D5DAD">
               <w:pPr>
                  <w:pStyle w:val="berschrift1RBHJB"/>
               </w:pPr>
               <w:r>
                  <w:t>Anhang</w:t>
               </w:r>
            </w:p>
            <w:bookmarkEnd w:id="70" w:displacedByCustomXml="next"/>
         </w:sdtContent>
      </w:sdt>

You can see, that the bookmarkEnd is INSIDE the sdt block!? I don't know why word does this, but it's the original document...

Hi Harald

I just had a look at this, and I think I've fixed it. But if you could email me your docx, I'll verify the fix works before sending you the update.

thanks .. Jason
