I recently asked for some help on indexed properties and I still some
assistance. However, I made some progress in the understanding of the
issue. I traced the Struts source code to understand a little better why
I'm loosing collection date in between Struts actions.
I have a very simple JSP (not using struts-layout here since I wanted to
test the most simple example possible). It uses a 'signals' property of
a my form names 'strategyForm'. See below.
When I hit the validate button, I have lost the 'signals' property. I
debugged Strsts source files and I realized that the request does not
have the 'signals' parameter (RequestUtils.populate() which calls
BeanUtils.populate() ).
==> QUESTIONS
- How do I make sure that an indexed property will be populated in the
form of a Struts action
- How to I make sure in the JSP file that the 'signals' property in the
HTML form ? Should I add a hidden field ? But how ?
Any response will be appreciated.
Below, you will find the entire JSP file and the relevant part of my
strategy form source code.
Thanks in advance for your help.
