I designed the page using netbeans ans used the generated code in my program. It gives me the following error. Can someone tell me what this error means?


Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.swing.JTextField[,0,0,0x0,invalid,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@4f6ac7f,flags=296,maximumSize=,minimumSize=,preferredSize=,caretColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],disabledTextColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],selectionColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],columns=0,columnWidth=0,command=,horizontalAlignment=LEADING] is not attached to a horizontal group

this has nothing to do with 'swings'

it is an IDE-specific layoutManager issue,
so you should post in that IDE's forum.

How about using one of the String constructors?

What do you mean by a String constructor? Please elaborate.

Check out the Javadocs for java.lang.String (<= just click). Check out the constructors section. See if you can create a String from a char[].

@OP can you edit your post to remove most of the error message?

it's a real PITA reading it on a phone (scrolling forever)
