--------------------------------
Resolution: Fixed
Fix Version/s: (was: 2.3.x)
2.3.17
see commit cb9f0f5645d05b2f1c7c66640716acff61c4425f
Modified UIBean class to not assign null value to id parameter
Ran all tests in struts2-core and they passed
Ran Struts 2 example applications that use form tags and example application
that duplicated the reporter's issue. Everything worked correctly.
> Components: "id" parameter is deleted

> Key: WW-4299
> URL: https://issues.apache.org/jira/browse/WW-4299
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Tags
> Affects Versions: 2.3.16.1
> Reporter: Walid Ghafir
> Assignee: Bruce Phillips
> Fix For: 2.3.17
>
>
> When using <s:component> tag, *parameter* named "id" is not accessible in
> component. That seems to be due to UIBean.populateComponentHtmlId() method
> which always overwrites it with value of *attribute* named "id", even if id
> attribute has not been specified.
> For example, here is a call to a test JSP component:
> {code}
> <s:component template="TestComponent.jsp">
> <s:param name="id" value="'testIdValue'"/>
> <s:param name="test" value="'testTestValue'"/>
> </s:component>
> {code}
> If TestComponent.jsp, {{parameters.test}} will have value "testTestValue" and
> {{parameters.id}} will be null although it's expected to be "testIdValue".
> I think that it's due to method {{populateComponentHtmlId(Form form)}} in
> {{org.apache.struts2.components.UIBean}} class that always does this, at the
> end of the method body:
> {code}
> addParameter("id", tryId);
> {code}
