[JBoss jBPM] - Re: using custom date picker in form within jbpm-console web
by rossputin
Hi,
this is really a question aimed at Ronald or anyone else who has or knows how to integrate the Richfaces date picker component into a jpdl generated form.
I have successfully put a richfaces date picker into the jbpm:dataform element...
| <rich:calendar value="#{calendarBean.selectedDate}"
| locale="#{calendarBean.locale}"
| popup="#{calendarBean.popup}"
| datePattern="#{calendarBean.pattern}"/>
|
but the value attribute which grabs the selected date from the calendar component is not written to the database when the form is saved, obviously because it would need to be 'value="#{var['due-date']}"' or some variable name like that. My first thought was to have a hidden input with 'value="#{var['due-date']}"', and then copy the date picker value into that, but I am unsure how I should execute javascript to do that upon form submission.
Has anyone integrated the date picker component so it writes its value to the database upon saving? I am having trouble understanding how to do this.
Thanks for your help,
Ross

[Tomcat, HTTPD, Servlets & JSP] - Re: Error in reloading jsp with taglib directive
by Grexe
Glad I am not alone with this... I get the same error here, with the following taglibs (as you can see this is a Struts-webapp):
<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html"%>
| <%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean"%>
I am on Java 1.4.2 and JBoss 4.0.4.GA_p1 (also tried 4.0.4.GA and 4.0.3SP1):

This has to be a configuration/installation-issue as my colleague could not reproduce this error yet on his (similar) setup. I will post any helpful input here, in the meantime I am grateful for any inspiration...
PS: The files are perfectly readable and I doublechecked the jsf-jars in \jbossweb-tomcat55.sar\jsf-libs

[JBoss Seam] - Using @DataModel and @DataModelSelection in different Sessio
by barfoos
Hi,
I want to separate DataProviding and EventHandling in my application
as much as possible. That's why I'm thinking of using one SessionBean
to provide DataModel for my facelets. Actions, that later will be triggered
from within the facelet by user events, should then be handeled in some
other session bean. I had two ideas on how to implement this, but none
succeeded. Could someone point me into the right direction?
Idea1:
| @Stateful
| public class DataProviderBean implements IDataProviderBean{
|
| @DataModel("entities")
| List<Entity> e;
|
| @Factory("e")
| public void initE(){ ... }
| }
|
| @Stateful
| @Name("EventHandler")
| public class EventHandler implements IEventHandler{
| @DataModelSelection(value="entities")
| Entity e;
|
| public event1(){
| // do some reasonable thing with e
| }
| }
|
This unfortunatelly does not even deploy, since seam tells me,
that it needs a @DataModel for each @DataModelSelection
within EventHandler.
My second idea was as follows:
| @Stateful
| public class DataProviderBean implements IDataProviderBean{
|
| @DataModel("entities")
| List<Entity> e;
|
| @DataModelSelection(value="entities")
| @Out("selectedEntity")
| Entity e;
|
|
| @Factory("e")
| public void initE(){ ... }
| }
|
| @Stateful
| @Name("EventHandler")
| public class EventHandler implements IEventHandler{
| @In("selectedEntity")
| Entity e;
|
| public event1(){
| // do some reasonable thing with e
| }
| }
|
|
But EventHandler.e did never get initialized with anything else than null.
Any ideas?
thanks and greetings
barfoos

[JBoss jBPM] - Re: Combo Box in Form
by kukeltje
anonymous wrote : pretty far from the truth....
hmmm... I read your post and do not see where jBPM is involved in a way that it is causing this problem. Everything you describe is JSF, the only thing is that you put selectItems in a variable, but that is just like you would do in in a bean. So basically all this is jsf stuff and jbpm is only invloved in a minor way. So I disagree that it is 'pretty far from the truth'
Yet, I do not disagree that a nicer solution would be 'handy' and seam provides parts of that for you. what you encounter now is in the grey area of the webconsole. What is it intended for? Production systems? well, the management part should be. Is it intended for end-users? No currently not. So some things are not in there and personally I use the storage of variables only in the RAD/Prototype part of a project. For productionsystems we have a separate domain model and use a separate database for that (with separate ui) so the list of selectitems comes from there and not jBPM. The selected value goes into jBPM.

I'm not saying what *you* encounter is a jsf problem, but up to where you are now was just JSF stuff. Could be that this instance-of thing is related to jBPM.
And yes, I will investigate since it would indeed be nice if the webconsole supported this out of the box in a fairly easy way. Care to help and build a nice more complex example of a ui with this in there?
