Hi, The problem seems to be that when you are using bean:write, the data you write is not included in the request when the page is displayed.So if you want to resedn the same data as part of request, use html:hidden along with bean:write.
I did not go in much detail of your code.But I think what you are looking for is indexed and nested property. You have to understand how struts prepolutaion tries to call properties on form from param name. 1.IF porperty is signal.code, when prepopulating, it will resolve to youForrm.getSignal.setCode(String aa) 2.IF porperty is signal[i].code, when prepopulating, it will resolve to youForrm.getSignal(i).setCode(String aa). Hope this helps.

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.
