Got multiple objects but only display one on the windchill table.How to display all of them?

[guide_me]

@ComponentBuilder({"erp.MaterialModelBuilder"})
public class MaterialModelBuilder extends AbstractComponentBuilder {

@Override
public ComponentConfig buildComponentConfig(ComponentParams componentParams) throws WTException {
 ComponentConfigFactory factory = getComponentConfigFactory();
 TableConfig tableConfig = factory.newTableConfig();
 tableConfig.setId("erp.MaterialModelBuilder");
 tableConfig.setLabel("物料数据");
 tableConfig.setSelectable(true);
 tableConfig.setActionModel("exportlisttofile_submenu");

 ColumnConfig o_id = factory.newColumnConfig("o_id", "o_id", true);
 o_id.setWidth(100);
 tableConfig.addComponent(o_id);
 return tableConfig;
}

@Override
public Object buildComponentData(ComponentConfig componentConfig, ComponentParams params) throws Exception {
 String number = (String) params.getParameter("part_number");
 String erpState = (String) params.getParameter("erp_state");
 String fromDate = (String) params.getParameter("fromDate");
 String toDate = (String) params.getParameter("toDate");

 return getMaterielModel(number, erpState, fromDate, toDate); // getMaterielModel() return a 3 size List
}

Do they have all a different oid? Each row needs to have a separate id, otherwise it's the same object.

[guide_me]

Their oid is different.

And I just find out only the last element of the returning list will display.

Hi @guide_me 

Is the MaterialModel OOTB type of object or is it yours custom type of object?

I had same issue with WTPart. Only the last one has been shown in the table. 

I use my own type in my table and I had trouble to show more usage with same WTPart object

I needed to change the oid from WTpart to UsageLink oid and then it worked

do you have getOid method with Override?

@Override
public NmOid getOid()
{
return this.nmOid;
}

Finally, it works. THX!

I would suggest, that you use not any special oid column. I always use:

  @Getter
  private              NmOid oid;

this.oid = new NmSimpleOid("12345");

please name the oid column "oid". This will save you some problems.

it works. THX!
