pageWithName crashes

  • Subject: pageWithName crashes

Hi,
Finally got things somewhat running on the new macbook (running eclipse 3.6 et woplips 3.6.6135 as well as the latest Wonder). The code that sued to work and is deployed did not compile. The most major thing was the refusal by the displaygroup editor to refuse the editingcontext to be specified as session.defaultEditingContext. Had to create a local variable ec (public for now) and use that instead. Now it compiles and runs with a crash at runtime (stack trace below).
Here are the tidbits of importance

PageMenu.java includes the following code
// __________________________________________________________________________________________________________________
public ProjectList goCoreProjectSearch() {
ProjectList aPage;
aPage = (ProjectList) pageWithName(ProjectList.class);    <-crashes in there
aPage.goCoreProjectSearch();
return aPage;
}
// __________________________________________________________________________________________________________________

ProjectList.java includes the following code
// __________________________________________________________________________________________________________________
public class ProjectList extends ERXComponent {
// variables deleted...
public ProjectList(WOContext context) {
super(context);   <-crashes in there
ec = session().defaultEditingContext();
dg = new WODisplayGroup();
dg.setNumberOfObjectsPerBatch(ERXProperties.intForKeyWithDefault("com.obzerv.objectsPerBatch", 25));

fs = EOFetchSpecification.fetchSpecificationNamed("projectsSearch", "Project");
log.debug("ProjectList EOFetchSpecification " + fs);

ds = new EODatabaseDataSource(session().defaultEditingContext(), "Project");
log.debug("ProjectList EODatabaseDataSource " + ds);

ds.setFetchSpecification(fs);
dg.setDataSource(ds);

editable = false;
projectStatusList = ProjectStatus.fetchAllProjectStatuses(ec, ERXS.ascs("sortOrder"));

}
// __________________________________________________________________________________________________________________
Tried using fully qualified package names and a few other things without success ...


Thanks in advance.
