Hi,

if let's say we have two controls, control1 and control2... how can we fill control2 based on modification of control1?
currently the word /hi/ is not being filled in control2 when i modify control1, why?

[Form]public class Form1 extends FormRun{    [Control(/String/)]    class control1    {        /// <summary>        ///        /// </summary>        /// <returns></returns>        public boolean modified()        {            boolean ret;                    ret = super();            if(ret)            {               Control2.text(/hi/);            }                    return ret;        }    }

Are the controls bounds to a data source? You code assumes that they aren't - and the assumption may be wrong.

And is it the same data source or two different ones?

Hi Martin,

Yes bound to a datasource and it's the same data source for both

Then forget individual controls and focus on data sources.

Also, is the logic specific to this single form or should it happen in all cases? If the latter, don't put it on the form at all - put it on the table itself, such as to modifiedField() method.

Hi

You Can add your code on form Control (override modified field), or DataSource level by overriding Modified field method, or on Table level. It depends on the logic that you want to apply.
