HTML form entry module doesn't run

I have added the HTML form entry module of version 2.5 onto OpenMRS version 1.12. While running the module. The following error pops up

Please fix all errors and try again. 
javax.el.ELException: Error reading 'links' on type org.openmrs.module.htmlformentry.extension.html.AdminList
org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:92)

org.hibernate.impl.QueryImpl.list(QueryImpl.java:102)
org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:890)

the other problem noticed is that while creating the form using the Form Entry Module. If the concept is boolean, it doesnt create the widgets stating that the value cannot be null.

Would like to know how to resolve these issues. Thank you

Hi Sharon,

My first suggestion would be to ask if you can use a released version of OpenMRS. Is there some reason you need the latest (potentially-unstable) master branch? I would suggest you build on 1.11.x instead.

Hello @darius

I have solved the issue with the help of Wyclif.

Thank you
