Using Synthetica components

Postby afanti » Thu May 22, 2008 2:41 pm


I use the Synthetica component library (
I am having problems using the components in Swing Designer. All of the ones I've tried break the parsing or yield a "Exception during creation of..." or similar.

Currently I'm looking at the DateComboBox (which has a zero argument constructor, and I believe is a valid bean (but I don't know how to be certain)).

In the hope someone can help me out. Here's a little bit of the log (can't figure out how to attach it).

java.lang.IllegalArgumentException: Cannot format given Object as a Date
at java.text.DateFormat.format(Unknown Source)
at java.text.Format.format(Unknown Source)
at org.jdesktop.swingx.JXDatePickerFormatter.valueToString(
at javax.swing.JFormattedTextField$AbstractFormatter.install(Unknown Source)
at javax.swing.JFormattedTextField.setFormatter(Unknown Source)
at javax.swing.JFormattedTextField.setValue(Unknown Source)
at javax.swing.JFormattedTextField.setValue(Unknown Source)
at de.javasoft.plaf.synthetica.datecombobox.DateComboBoxEditor.setItem(

Please let me know what I can do to bet to the point where I can use my favorite component set with my favorite GUI designer tool. Thank you.

The DateComboBox class was throwing an unexpected exceptiosn which was preventing the rest of the contents of the JFrame from painting. We had never seen a widget that did that. We added a work around to avoid that problem, so please try this again with the latest Swing Designer build.
