java.lang.ClassCastException: org.docx4j.wml.R cannot be ca

[abuzekry]

I have an Object o, which I'm trying to cast to org.docx4j.wml.Text. get it's parent and then cast to javax.xml.bind.JAXBElement. The parent returns a org.docx4j.wml.R and then the casting gives a java.lang.ClassCastException, is this an expected behaviour? how can I do the casting correctly

The condition I'm trying to check is

Code: Select all

if (!((javax.xml.bind.JAXBElement)((org.docx4j.wml.Text) o).getParent()).getName().getLocalPart().equalsIgnoreCase("instrText"))

For starters, if things aren't working as you expect, don't try to do it all in one line of code...

It looks/sounds like you are trying to cast wml.R to javax.xml.bind.JAXBElement

That won't work, and you should expect the exception. See https://github.com/plutext/docx4j/blob/ ... R.java#L70

I suspect you want to know whether the R content is instrText? At https://github.com/plutext/docx4j/blob/ ... java#L3364

Start by iterating through the content and printing out the name of the objects. If it is a JAXBElement, cast to that and use JAXBElement's methods to see what it wraps.

Thank you so much for this.
