Originally posted by: mirk.tonia.ch
I'm trying to integrate search support into my plugin.
i wrote a own search page and now i want to display the results in the search view.
i took a look at the help search page implementation to find out how this is done.
the search operation runs without an exception but the search result is not
displayed. only after i run a second search i can display the first search by
using the "previous search result" button in the search result view's toolbar.
after that the search result is diplayed corectly. but when i try to remove a search
result with the the "remove selected match" or "remove all matches" action of the search
result view, the match won't go away ( it is still displayed but trying to run the gotoaction
results in in a org.eclipse.core.internal.resources.ResourceException: Marker id: 1824 not found.)
below i posted my performAction method ( SearchPage implementation ) and
my implementation of the searchoperation ( BSPSearchOperation )
thanks for your help
ps im using
Version: 2.1.1
Build id: 200306271545
on linux ( gtk version )
i have not tryed on other platforms so far
my perform action looks like this
public boolean performAction() {
SearchUI.activateSearchResultView();
// get the runnableContext
IRunnableContext context= null;
context= getContainer().getRunnableContext();
if (context == null)
context= new ProgressMonitorDialog(getControl().getShell());
BSPSearchOperation op = new BSPSearchOperation(
new EOFetchSpecification( AntragSteller.ENTITY_NAME(), qualifierPart.getQualifier(), null),
PAGE_ID
);
try {
context.run(true, true, op);
} catch (InvocationTargetException ex) {
ExceptionHandler.handle(ex, SearchMessages.getString("Search.Error.search.title"),SearchMessages.getString( "Search.Error.search.message")); //$NON-NLS-2$ //$NON-NLS-1$
return false;
} catch (InterruptedException e) {
return false;
}
IStatus status= op.getStatus();
if (status != null && !status.isOK()) {
String title= SearchMessages.getString("Search.Problems.title"); //$NON-NLS-1$
ErrorDialog.openError(getShell(), title, null, status); //$NON-NLS-1$
}
return true;
}
