I have added a JFileChooser to my application and changed its dialogType to SAVE_DIALOG and customized the approveButtonText property.

Unfortunately, my customized approveButtonText never shows up because NetBeans positions the source code like this:

        fileChooser.setApproveButtonText("Save me");
        fileChooser.setDialogType(javax.swing.JFileChooser.SAVE_DIALOG);

If you look at the source of JFileChooser.setDialogType() you will notice the following code block:

	if(dialogType == OPEN_DIALOG || dialogType == SAVE_DIALOG) {
	    setApproveButtonText(null);
	}

This means that calling JFileChooser.setDialogType() nulls the customized approveButtonText.

Therefore NetBeans must position setApproveButtonText() after setDialogType(), like this:

        fileChooser.setDialogType(javax.swing.JFileChooser.SAVE_DIALOG);
        fileChooser.setApproveButtonText("Save me");
