Best Practice Name and Classification

Merge filter criteria and smart collection in BOM Transformer

Objective

Provide customization guidelines for merging a filter with a smart collection in MASPB

Prerequisite Knowledge

To apply this best practice, you need to have an understanding of the following:

• Basic knowledge of MPMLink and BOM structure

• Basic development involving Java

• The management of *-actions.xml, *-actionmodels.xml, and *.xconf files customizations

Solution Elements

Open a smart collection on which an existing filter, for example, saved NavigationCriteria is applied. Now apply a new or custom filter, for example, client NavigationCriteria on the smart collection. To merge the new and the existing filter criteria, that is, merge saved NavigationCriteria and client NavigationCriteria, perform the following procedure:

1. Write a new custom delegate that extends the existing com.ptc.windchill.associativity.delegate.OpenAMInStructureBrowserDelegate delegate.

For example, CustomOpenAMInStructureBrowserDelegate.

2. Override the following method and add the customization code:

public NavigationCriteria mergeNC(NavigationCriteria savedNc, NavigationCriteria clientNc)throws WTException;

The sample code is as follows:

import com.ptc.windchill.associativity.delegate.OpenAMInStructureBrowserDelegate;
import wt.filter.NavigationCriteria;
import wt.util.WTException;
public class CustomOpenAMInStructureBrowserDelegate
extends OpenAMInStructureBrowserDelegate{

@Override
public NavigationCriteria mergeNC(NavigationCriteria savedNc, NavigationCriteria clientNc) throws WTException {
// customization code to put filters or configuration specification from savedNc to clienNC
return clientNc;
}
}

3. Update the xconf entry for a new class. For example, CustomOpenAMInStructureBrowserDelegate.

4. Remove an entry for OpenAMInStructureBrowserDelegate delegate in com/ptc/windchill/associativity/xconfs/associativity.service.properties.xconf file.

The sample code is as follows:
