Error in loading component property (Swing GUI Forms)
- by Christo Du Preez
For no apparent reason all my Swing GUI forms using components linked to org.jdesktop.beansbinding.Converter started generating errors when trying to open the Design View:
Error
Error in loading component property: [JPanel]-filterTextField-converter.
Cannot load property type class org.jdesktop.beansbinding.Converter.
The property cannot be loaded.
Errors occurred in loading...
I'm currently using Netbeans 6.8. I opened my project in Netbeans 6.7.1 and all was fine but after a while the same thing happened. Looking at the .form and .java files and comparing it to previous backups, everything looks fine. Even my Netbeans tutorial project no longer works.
What can cause this. Any suggestions would greatly be appreciated.
After further investigation this is taken from my IDE's log :

Error in loading component property: Other Components-mainPanel-jTextField1-converter
Cannot load property type class org.jdesktop.beansbinding.Converter.
The property cannot be loaded.
Can someone please help me with this issue. This is still not resolved and not being able to edit my Forms or loosing binding properties every time I need to edit a Form is a real pain and time consuming! Any help would greatly be appreciated. Thanx.
