[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
Hi,
I just come to add precisions on my previous solution (it can eventualy help).
Finally there is a big problem with the previous solution : you can't control
the result of the servlet and the task is always validated. It didn't matter
for me so far... but now I need it.
So I came back to the old solution and I'm now validating my task and
everything in the servlet with the taskInstance ID I get in EL like that :
#{taskInstanceBean.taskInstance.id}

[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
I just solved my problem. I was trying to get my taskInstance to be signaled
with code when I thought about another solution :
I don't put a dataform inside my form but the form inside my dataform. This way
the default transition button can still work and I just have to put some
javascript on it like that :
jbpm:dataform
| f:facet name=header
| Envoyer un fichier local
| /f:facet
| jbpm:datacell
| f:facet name=header
| Selectionnez le fichier a envoyer :
| /f:facet
| form name=uploadFile enctype=multipart/form-data
method=POST action=uploadSuivi
| input class=file type=file name=suiviXLS/
| input class=text type=hidden name=nomProjet
value=#{var['nomProjet']}/
| /form
| /jbpm:datacell
|
| jbpm:datacell
| f:facet name=header
| h:outputText value=Actions/
| /f:facet
| tf:transitionButton transition=OK value=Envoyer
onclick=document.forms['uploadFile'].submit();/
| /jbpm:datacell
| /jbpm:dataform
It works well, my task is validated, the next task is created, my servlet is
called and my file saved... I'm happy but I'm feeling very stupid to think
about that so late. I knew this should be easy :)
Btw I think a little more documentation must be written on EL (some examples
would be great) and since jBPM JSF tags are still here in the new admin console
and usable from jBPM and JSF users, I think they deserve a little Javadoc like
the official JSF one :
http://java.sun.com/javaee/javaserverfaces/1.2_MR1/docs/tlddocs/index.html.
That's absolutly not a urgent task... but it would help...

I forget to say it again : I know I may I misunderstood the documentation. I d'ont say it's a bug... but in case I read well it can be... I just don't know and I'm curious about it. What I want now is another solution to get my process instance, token or whatever so I can signal my task in my servlet. I'm sure there's an easy one somewhere but I just don't imagine it yet...

Well,
tokenId=item.getString();
differs from tokenId=tokenIdItem.getString();
and the accompanying form tells more about the 'correct' implementation than
single lines of code, so please let us be the judge of whether it tells
more/enough ok ;-)
What does the generated form look like in the browser? Does the token field
have a value?
Maybe try something like #{task.token.id)
Whow... now I see where you go wrong..
you do a token.getId instead of token.id..

[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
I doesn't work better with id at the end or/and with task in the begining. My field remains empty (and empty in the browser too if not hidden). I tried idParameter instead of id only too (I see that in a jbpm:bind... just in case...) and it doesn't work better. Right now I'm trying to add the processInstance ID to the context variables with an action. That way I'm sure I'll get it in my servlet. It doesn't work yet but it will... I hope it will :) Too bad I have to add code and use a process variable for that though...

[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
Ronald, I see a lot of instances on the forum of folks who have problems with EL and don't (apparently) have any way to dig into what they've done wrong beyond inspection of their code. It's much more common with transition condition expressions. Do you know if there's any way to turn on EL tracing so that, e.g., in this case, he'd see somewhere in a log a No Such Field 'getId' error message? -Ed Staub View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4049289#4049289 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4049289 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
Ed,
This is generic EL stuff ig you have e.g. a class Token with getter/setter
like getId/setId, in EL you have to use token.id to have access to it.
If it is the jboss imp, it uses log4j, so turning on debug at the rootlevel
(and reducing it to the correct classes/packages if you see some interesting
stuff) is what I normally do.
In the webconsole I see something like:
| jbpm:dataarea
| h:inputHidden value=#{returnViewId}/
| h:inputHidden value=#{tokenId}/
| ...
| /jbpm:dataarea
|

The log can provide this - maybe. I haven't used it in this area, so I don't know what log output is emitted and whether it is useful.

Yes... I'm getting a sense that a lot of folks don't have the experience base for this to be an reflexive thing to do. I'm starting to wonder if it makes sense to include a log4j.xml in the config, just to steer folks toward taking advantage of it. I guess JBPM may migrate at some point to use Seam's EL implementation relatively soon, so researching into specifics about log capabilities in the current implementation may not be that useful in the long term. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4049313#4049313 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4049313 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
Oh... regarding these logoutputs, I have some experience in combination with seam and there is explicit logging on getters/setters not found on debug level. Sometimes even at error (not sure when exactely) There was a configfile at the debug level, but afaik, there has been a change in policy lately to at least leave the console output with not that high a level and have the fileappender contain more detailed output, so not only look at the console And yes, if it was up to Gavin et al, jBPM would make the switch to their EL impl asap (not sure if that one runs on jdk 1.4 though View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4049318#4049318 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4049318 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: Signal a task on a html form submit
Just some precisions :
- I spent lot of time trying everything (taskInstance, processIntance and not
only token) in my expressions and I never get any answer. I don't know why
since it works well with any simple variable (with #{var['myvar']}).
- This input code is in a modified form file created by the GPD. I need to have
2 solutions here : the first is a normal transition link and the second the
file upload. They lead to the same unique transition to the next node.
I searched the documentation and I understand that the way I do it should
work.. is it a bug? (I'm not know EL enough to figure myself)
I searched in all the test cases and I didn't find any example of that... did I
miss one?
I lost nearly a day on that so if you have any little idea... even if it may
seem stupid... I'll take it and test it.
