jbpm task forms as generated by jpdl eclipse plugin

[rossputin]

Hi guys,

I am having difficulty with forms, if I try to specify a form looking like...

<jbpm:dataform columns="3">

 <f:facet name="header">
 <h:outputText value="#{taskName}"/>
 </f:facet>

 <!-- TASKFORM ROWS -->
 <jbpm:datacell>
 <h:outputText value="Milestone 1"/>
 </jbpm:datacell>
 <jbpm:datacell>
 <h:inputText value="#{var['milestone1']}" />
 </jbpm:datacell>
 <jbpm:datacell>
 <h:inputText value="#{var['due-date']}" />
 <div id="cal1Container"></div>
 </jbpm:datacell>

I get the following error...

javax.servlet.ServletException: Servlet execution threw an exception

root cause

java.lang.OutOfMemoryError: Java heap space

I experimented putting facets in there, but periodically get the same error..

can anyone provide a sample 3 column table layout using the dataform and datacell approach.

I am also curious as to how I would implement making form fields mandatory within my tasks...

thanks for your help in advance,

Ross

I suppose it is possible I can just put any old handcrafted xhtml form with javascript for mandatory variable checking, and it is not required that I use the dataform and datacell components ? Or is there hardwiring for the save button that it would be difficult to duplicate ?

Ross,

fyi, there is a pretty similar bug in JIRA for the jbpm:dataform with multiple columns already:
http://jira.jboss.com/jira/browse/JBPM-1039

You might want to check this out.

thanks for pointing that out, does that mean I can put three rows in without specifying the columns attribute on the dataform element?

cheers

also is it possible to put a javascript script tag in the task form.xhtml file to do validation on form elements ?

cheers

required in jpdl means not null. JSF by default returns an empty, non-null string. So put a 'required=true' on the input. That will make sure a real value is needed

Hi,

I am clicking on the generate form button, and specifying my variable there, I am clicking on the required=true checkbox, but it seems to have no effect... so should I manually in my xhtml form specify 'required=true'? Is that the syntax?

thanks for your help,

Ross

Ah, I see what you mean, I can now specify mandatory fields upon pressing the 'save' button...

my problem is that I always want to automatically show a form whenever there is one for a given task, so on my web page I have the form, its 'save' button, and all of my transition links, so I would like to check for completion of mandatory fields upon clicking on the transition links also, do you have any ideas how I could implement this ?

thanks for your help,

Ross

??? you mean without having to add the 'required=true' manually in the form? Only one solution, change the formgenerator in the GPD and contribute the fix back... ;-)
