Suppose,
valueChangeListener="BB.txtChngLsnr1" id="inputText1" for 1st inputText
valueChangeListener="BB.txtChngLsnr1" id="inputText2" for 2nd inputText
then,
txtChngLsnr1(ValueChangeEvent vce){
if(vce.getNewValue=null){
return; // optional case
}
if(inputText2.getValue== null){
//
/*
*
*error code
*/
FacesContext.getCurrentInstance().renderResponse();
}
}
Similarly the code for the second value change listener can be.
txtChngLsnr2(ValueChangeEvent vce){
if(vce.getNewValue==null){
return; // optional case
}
if(inputText1.getValue== null){
//
/*
*
*error code
*/
FacesContext.getCurrentInstance().renderResponse();
}
}
see if this works, and tell if any problem comes.

Dear all,
I have a form which has two <tr:inputText> elements, if first element has
value, then the second element must have value as well. If first element
doesn't have value, then the second element is optional.
Vice versa, if the second element has value, then the first element must have
value. If the second element doesn't have value, then the first element is
optional.
How can I implement this in trinidad? Thanks in advance!
Kind regards,Leon
