Hi Malcolm
We are using the Form.setError(String error) for displaying the error
messages on the Form, referring the Apache Click samples. We generate the
string parameter ‘error’ as an HTML including the java script to focus
relevant ‘Field’, sample code snippet is pasted below. We have also
researched the floating error messages (Form using the jQuery Validator )
provided by ClickClick and JQuery integration
(jquery-examples/ajax/validation/jquery-validation1-demo.htm).
I would be interested to know more about the ‘*flash variables*’. I would
appreciate, if you can please elaborate more on topic and guide me with an
hosted example/sample (if any).
private String getError(Field field) {
StringBuffer buffer = new StringBuffer();
buffer.append("<br>");
buffer.append("<a class=\"error\"");
buffer.append(" href=\"javascript:");
buffer.append(field.getFocusJavaScript());
buffer.append("\">");
buffer.append(field.getError());
buffer.append("</a>");
return buffer.toString();
}
Thanks in advance,
Manjit Oberoi
