Custom Webject not working as expected

[RG_10893406]

I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.2.0

I have created two webjects one is Search-Objects and another is custom webject. I'm passing the object id to the custom webject as input and I am getting the actual value as a output. But the issue is, in the output result only for the last object the custom value is showing not for others.

@RG_10893406.. can you upload the two webjects you are using?

[RG_10893406]

From Search-Objects webject im getting the parts details, and Context-Name Webject is the custom webject which we have created. Using Return-Group webject im combining both webject data. But the data is not combining. The custom data is showing for only the last object.

<%@page language="java"%>
<%@taglib uri="http://www.ptc.com/infoengine/taglib/core" prefix="ie"%>

<ie:webject name="Search-Objects" type="OBJ">
<ie:param name="INSTANCE" data="$(@FORM[]supporting-adapter[*])" delim="!" valueSeparator="!" default="<%=com.infoengine.au.NamingService.getVMName()%>"/>
<ie:param name="TYPE" data="wt.part.WTPart"/>
<ie:param name="attribute" data="obid,number,name,version,lifeCycleState,containerReference" delim=","/>
<ie:param name="GROUP_OUT" data="objectSearched"/>
</ie:webject>

<ie:forEach groupIn="objectSearched" groupOut="Obj">

I did not get any solution. I am still searching for the solution.

Please let me know if anybody aware of it. It will be helpful for me.

If it helps you solve it, they asked to see the webject but what you sent is the code which implements an info engine task to call the webject. You need to show java code the webjects

[RG_10893406]

Please check the below java code

public class ExampleCustomWebject {

private static WTPart part = null;

private static Vector getColumnElements(Task task) throws IEException {

Webject w = task.getWebject();

String grp_out = null;

String column = null;

String grp_in = null;

Group group_in = null;

Param param = w.getParam("COLUMN");

if (param == null)

throw new GroupWebjectException("ExampleCustomWebject: no COLUMN");

column = param.getData();

param = w.getParam("GROUP_IN");

if (param == null)

group_in = task.getGroupIn();

else

group_in = task.getVdb(param.getData());

if (group_in == null)

throw new GroupWebjectException("ExampleCustomWebject: no GROUP_IN");

int element_count = group_in.getElementCount();

Vector elements = new Vector();

for (int i = 0; i < element_count; i++) {

Element e = group_in.getElementAt(i);

Vector ev = e.getValues(column, true);

if (ev == null)

continue;

for (int j = 0; j < ev.size(); ++j)

elements.addElement(ev.elementAt(j));

}

if (!(elements.size() > 0))

throw new GroupWebjectException("ExampleCustomWebject: no COLUMN \"" + column + "");

return elements;

}

public static Task contextName(Task task) throws IEException {

// public static List<Task> contextName(Task task) throws IEException {

System.out.println("Inside getContextName() " + task.getName());

try {

Object val;

String objId = "";

String grp_out = null;

String column = null;

String contextName = "";

List<String> finalContext = new ArrayList<>();

Task response = new Task();

// List<Task> response = (List<Task>) new Task();

Webject w = task.getWebject();

System.out.println("Group_IN name " + w.getGroupInName());

System.out.println("Group_Out name " + w.getGroupOutName());

System.out.println("Webject name " + w.getName());

Param param = w.getParam("GROUP_OUT");

System.out.println("Param Value " + param.getName());

System.out.println("Param Value " + param.getData());

if (param == null)

throw new GroupWebjectException("contextName: no GROUP_OUT");

grp_out = param.getData();

param = w.getParam("COLUMN");

if (param == null)

throw new GroupWebjectException("contextName: no COLUMN");

column = param.getData();

System.out.println("column " + param.getData().toString());

Vector elements = getColumnElements(task);

System.out.println("elements " + elements.size());

for (Enumeration en = elements.elements(); en.hasMoreElements();) {

val = en.nextElement();

System.out.println("Value " + val.toString());

objId = val.toString();

String[] parts = objId.split(":");

if (parts.length >= 3) {

String result = parts[0] + ":" + parts[1] + ":" + parts[2]; // VR:wt.part.WTPart:2132727

System.out.println(result);

contextName = getContexttName(result);

System.out.println("Context Name is " + contextName);

finalContext.add(contextName);

System.out.println("finalContext " + finalContext.size());

}

}

com.infoengine.object.factory.Element elem = new com.infoengine.object.factory.Element();

Att att = new Att(column + "ContextName");

att.addValue("" + finalContext);

System.out.println("ATT " + att.toString());

elem.addAtt(att);

System.out.println("element " + elem.getName());

Group group_out = new Group(grp_out);

group_out.setElement(elem);

System.out.println("group_out " + group_out.getStatus());

System.out.println("group_out to string " + group_out.toString());

response.addVdb(group_out);

return response;

} catch (Exception exc) {

exc.printStackTrace(System.err);

if (exc instanceof IEException)

throw (IEException) exc;

throw new IEInternalServiceException(exc);

}

}

private static String getContexttName(String obid) throws WTException {

ReferenceFactory rf = new ReferenceFactory();

WTReference reference = (WTReference) rf.getReference(obid);

Persistable pers = (Persistable) reference.getObject();

String newName = "";

if (pers instanceof WTPart) {

newName = ((WTPart) pers).getContainerName();

}

return newName;

}

}

This would work but another option for less effort could be to extend the already existing ObjectWebject class that already has that function. In the example below you can use getUfidsAsGroup then loop through the group and perform actions on each element, like get the context just for an example, then add to the group_out.

Task:
