Subject [jira] [Commented] (WW-4299) Components: "id" parameter is deleted
Date Wed, 19 Mar 2014 07:53:43 GMT


ASF subversion and git services commented on WW-4299:

Commit cb9f0f5645d05b2f1c7c66640716acff61c4425f in struts's branch refs/heads/feature/WW-4187-correctly-identify-protocols
from phillips1021
[;h=cb9f0f5 ] - do not assign value to id parameter if tryId
value is null this prevents overwriting a parameter with a name of id used with the component

> 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 {{}}
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}
