Stephan commented on WW-5077:
-----------------------------
^Thank you for the tip. I have updated my struts configuration as seen below^
{code:java}
<interceptors>
<interceptor name="ParametersInterceptor"
class="com.opensymphony.xwork2.interceptor.ParametersInterceptor" />
<interceptor-stack name="appDefault">
<interceptor-ref name="ParametersInterceptor">
<param name="paramNameMaxLength">2000</param>
</interceptor-ref>
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
{code}
^Now all values values seem to be set if i am not mistaken. Still, in the Logs
i see following messages^
{code:java}
Parameter
[metadata.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name]
is too long, allowed length is [100]
{code}
^This is weird, as in the logs i see also that it sets all parameters^
{code:java}
Setting params
metadata.metadataList[0].metadataList[0].metadataList[0].metadataList[0].name
=> Level-5_new
metadata.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name
=> Level-6_new
metadata.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name
=> Level-7_new
metadata.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name
=> Level-8_new metadata.name => Level-1_new metadata.metadataList[0].name =>
Level-2_new metadata.metadataList[0].metadataList[0].name => Level-3_new
metadata.metadataList[0].metadataList[0].metadataList[0].name => Level-4_new
{code}
^In addition, since i am overriding the Interceptors^ ^paramNameMaxLength^
^value, shouldnt the Debug message "^^Parameter is too long, allowed length in
[100]" not appear anymore ?^

> I implemented a simple struts2+tiles (Struts 2 core version: 2.3.24.1) as a
> test case to verify an issue that have.
> In detail, i have the following Struts form:
> {code:java}
> <s:form action="save">
> <s:hidden name="metadataTest.name" value="Level-1_new" />
> <s:hidden name="metadataTest.metadataList[0].name"
> value="Level-2_new" />
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].name" value="Level-3_new"
> />
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-4_new" />
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-5_new" />
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-6_new" />
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-7_new" />
> <s:submit/>
> </s:form>
> {code}
> The metadataTest class:
> {code:java}
> public class Metadata implements Serializable {
> /** The Constant serialVersionUID. */
> private static final long serialVersionUID = 5902230367443812176L;
> private String name;
> private ArrayList<Metadata> metadataList;
> public Metadata() {
> }
> public String getName() {
> return name;
> }
> public void setName(String name) {
> this.name = name;
> }
> public ArrayList<Metadata> getMetadataList() {
> return metadataList;
> }
> public void setMetadataList(ArrayList<Metadata> metadataList) {
> this.metadataList = metadataList;
> }
> }
> {code}
> My issue here is following. When i submit this form, all values up to this
> level, are set correctly
> {code:java}
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-6_new" />
> {code}
> For some reason the below hidden element is never set, instead, the
> medataList at level 6 is null, while the name set by the hidden field above,
> is set correctly.
> {code:java}
> <s:hidden
> name="metadataTest.metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].metadataList[0].name"
> value="Level-7_new" />
> {code}
> Is there any kind of limitation by struts concerning the depth in a list
> hierarchie or maybe the length of path to set a value ? I could not find
> something related.
> *Note 1*: It surely has to do something with the length of the parameters.
> Once i changed the variable names to longer ones, i was able to set values
> only up to Level 3.
> *Note 2*: Downgrading to Struts 2.1.6 resolves the issue. Also latest version
> 2.5.22 seems to be afffected from the exact same issue. Is there any
> workaround ?
