[Trinidad] How to use PPR and a valueChangeEvent to update components in a tr:table row

[Graeme Steyn]

Hi,

I have a table with a tr:inputText field that I have attached a jquery
autocomplete function to.  When the value of this input field changes, I
would like to do a PPR operation that updates corresponding hidden input
and select one choice components in the same row.  The code for the two
columns appears below.

Within the institutionValueChange event code, how would I access the
"constHep" and "constCntry" components to update their values and in the
case of the "constCntry" disable the component based on the new value.

Any points would be greatly appreciate.

Thank you.

Regards,

Graeme.
