The eForms Core Library is a collection of utilities used by the EFX Toolkit for Java Developers and other eForms applications.
In version 1.8.0 we fixed an issue in XPathProcessor.join which used to compute valid but inaccurate XPaths when combining XPath steps. In version 1.9.0, we added a Simplification parameter to the same method, allowing the caller to control if and how the combined XPath is shortened. A backwards-compatible XPathProcessor.join method was kept, but deprecated for removal in the next major version.
You can download the latest eForms Core library from Maven Central.
