Lukasz Lenart commented on WW-4913:
-----------------------------------
That doesn't matter, data submitted via HTTP are coming as Strings, so you must
tell Struts how to convert a String into a {{ValueHolder}}.
See this
https://struts.apache.org/core-developers/type-conversion.html#creating-a-type-converter
> when using an custom array as a filed in struts 2 action form textfiled data
> from jsp page in not populating into custom array but populating in String
> array or array list
