Hello all,

I’m trying to get Portal comments into a form task.  
For a first try, I want every comments without any other filter than being the current Case.  
I don’t know what’s wrong. I’ll appreciate any help you may provide. Thanks.

I coded a groovy expression in a text area widget (General \> Data \> Initial value):

import org.bonitasoft.engine.api.ProcessAPI; import org.bonitasoft.engine.session.APISession; import org.bonitasoft.engine.search.impl.SearchResultImpl; import org.bonitasoft.engine.search.impl.SearchOptionsImpl; import org.bonitasoft.engine.search.impl.SearchFilter; import org.bonitasoft.engine.search.SearchOptionsBuilder; import org.bonitasoft.engine.bpm.comment.Comment;

ProcessAPI proAPI = apiAccessor.getProcessAPI();  
SearchOptionsBuilder filtro = SearchOptionsBuilder.filter(‘processInstanceId’, processInstanceId);  
List comentarios = proAPI.searchComments(filtro.getFilters());  
return comentarios.toArray().toString();

This is what I get at engine log:  
2014-09-15 16:02:30 org.bonitasoft.forms.server.FormsServletExt  
SEVERE: Error while getting the first page for id Expense Claim–1.3–1st Approval$entry

Ola / Hi Ana

Try with this code, note that I instantiated SearchOptionsBuilder, I set up this on done status, and I get the result from the SearchResult which is a List 🙂

import org.bonitasoft.engine.api.ProcessAPI; import org.bonitasoft.engine.session.APISession; import org.bonitasoft.engine.search.impl.SearchResultImpl; import org.bonitasoft.engine.search.impl.SearchOptionsImpl; import org.bonitasoft.engine.search.impl.SearchFilter; import org.bonitasoft.engine.search.SearchOptionsBuilder; import org.bonitasoft.engine.bpm.comment.Comment; import org.bonitasoft.engine.bpm.comment.SearchCommentsDescriptor;

ProcessAPI proAPI = apiAccessor.getProcessAPI();  
SearchOptionsBuilder filtro = new SearchOptionsBuilder(0,Integer.MAX\_VALUE);  
filtro.filter(SearchCommentsDescriptor.PROCESS\_INSTANCE\_ID, processInstanceId);

List comentarios = proAPI.searchComments(filtro.done()).getResult();  
return comentarios.toArray().toString();

And as a comment, it is better to use the SearchDescriptor instead of a constant, it can change in further versions…

You can find more examples on searches here  
[http://documentation.bonitasoft.com/search/site/SearchOptionsBuilder](http://documentation.bonitasoft.com/search/site/SearchOptionsBuilder)

Cheers

Hi,  
Thank you very much. That’s what I was searching for.  
I’ve seen information about the SearchCommentsDescriptor and suppose that KIND may be used to identify user comments (in order to ignore system comments), but I don’t know exactly what values I may use in the descriptor. Didn’t find that in documentation.  
Cheers

Ana,  
if you use the method [searchCommentsInvolvingUser](http://documentation.bonitasoft.com/javadoc/api/6.3/index.html) you will see the ones related with user [no system ones], may be is useful for you

```
	SearchResult<Comment> commentResult = pAPI.searchCommentsInvolvingUser(user.getId(),soU);
	for(Comment c : commentResult.getResult()){			
		System.out.println(c);
	}

```

And as note, in subscription you can disable it and/or translate them (system ones)

Thanks Pablo,  
That’s not exactly what I was searching for. I wanted to exclude system messages and display only user messages in a task form: it may be any user that participate in the instance.  
I’ve managed to get this to work: because system messages don’t have a userId, when displaying messages, I ignored them.  
Thanks for all your support. 🙂
