                                                         java.lang.String processType,

                                                         FilterFactory filtFactory)

Tries to retrieve the template of the designated process type having the highest version number in the template manager. Only released, instantiable and top-level usable templates will be recognised. If no such template is found (the process type is unknown or the filter yields an empty result, null will be returned.

Important! This method has some serious restrictions:
Due to the non-linear versioning of templates, the result of this method is ambiguous. It just retrieves the template with the highest version number which need not be the latest version at all. Additionally, the template manager need not know all templates of a process type and therefore only a subset of all templates of the process type may be considered.
Last but not least, the "interface" of a process type may change between two versions, that is, templates of the same process type may have different input and output parameters. Therefore the "latest" template may be incompatible to the calling context.

Parameters:

session - The session with which to retrieve the templates.

processType - The name of the process type of which to get the "latest" template.

templMgr - The template manager from which to retrieve the template.

filtFactory - The filter factory for creating the filters that apply to the templates.

Returns:

The "latest" template of the designated process type from the designated template manager. This is the instantiable top-level template having the highest version number. If no template is found for the designated process type, null will be returned.
