Hi Michael,
I run in the same issue days ago. I could not find a proper solution for
Struts 1.0.*. The right answer, I think is using String[] as type of data in
ActionForms. By instance, you can wrap all HTML inputs (<html:text
property="inputs[1]">) in a unique parameter:
String[] inputs with get and set methods in handling the String[]. In the
JSP, you set property as equals input[1], input[2].... for the different
inputs. The same could be applied for checkboxes, radios, or selects.
- In Struts 1.1b1, if you set a breakpoint at validate() method in
ActionForm, by instance, you will find the parameter input filled with
values collected from the JSP, so you can process them. Same applies for the
selects, radios and checkboxes. This behaviour does not seems to work in
Struts 1.0.*, I guess that by some bug in fetching indexed property values.
- Either in Struts 1.0.* or 1.1b1, if you preset the String[] with values,
JSP will show them when displayed.
I have not test it, by I suppose you can use DynaActionForms and define
String[] in the struts-config....
Hope it helps.
