Topsy Kretts commented on WW-3485:
----------------------------------
I just had a similar problem, and figured out what is the solution:
I tried to access this map:
private Map<Long, String> propertiesMap;
In the jsp originally used the struts tag like this:
<s:textarea name='propertiesMap["%{#attribute.id}"]'
id="propertiesMap_%{#attribute.id}" label="%{#attribute.attributeName}"/>
With the Struts version 2.2 I got null in the Action, so I changed the the line
above:
<s:textfield name="propertiesMap[%{#attribute.id}]"
id="propertiesMap_%{#attribute.id}" label="%{#attribute.attributeName}"/>
And then it works.
The notable change between the two lines is, there aren't quotes in the second
one.
Doesn't work with Struts 2.2:
name='propertiesMap["%{#attribute.id}"]'
Does work with Struts 2.2:
name="propertiesMap[%{#attribute.id}]"
I don't really know if it is a bug, but I think you can use this solution.
I hope this helped.

> The usage of a map of String * Bean which was working fine with Struts
