Custom forms not displaying using starter kit
molinemc Jan 21, 2007 8:58 PMHi,
I'm new to JBoss and jBPM, so I apologize if my question is improperly phrased. I'm attempting to get a new process working using the 3.1.3 starter kit, the Eclipse graphical process designer and the supplied webapp. I am attempting to use a custom TaskControllerHandler implementation to handle form input, but have had little success. My intuition is that I should create a custom xhtml file to use with the task that uses the task variables, and supply the link to it in the forms.xml file. However, no matter what I do, the webapp loads an empty form on the start state. I'd appreciate any help you can give.
Here are what I think are the relevant code snippets:
ProcessDefinition.xml:
... <task name="Input Top-level task" swimlane="initiator"> <controller class="<package_name_concealed.ProcessCreatorTaskControllerHandler" config-type="bean"></controller> </task> ...
ProcessCreatorTaskControllerHandler.java:
... public class ProcessCreatorTaskControllerHandler implements TaskControllerHandler { private static final long serialVersionUID = -8342109418315801711L; public void initializeTaskVariables(TaskInstance taskInstance, ContextInstance contextInstance, Token token) { taskInstance.addVariableInstance( VariableInstance.create(token, "processName", "")); } public void submitTaskVariables(TaskInstance taskInstance, ContextInstance contextInstance, Token token) { ... } }
forms.xml:
<?xml version="1.0" encoding="UTF-8"?> <forms> <form task="Input Top-level task" form="ProcessInput.xhtml"/> <form task="Input Task Info" form="InputTask.xhtml"/> </forms>
ProcessInput.xhtml
... <!-- TASKFORM ROWS --> <tr> <td>processName</td> <td> <input jsfc="h:input" value="#{taskBean.variables['processName']} /> </td> </tr> ...
Here is the HTML from the webapp, missing any reference to processName:
... <h2>Input Top-level task</h2> <hr /> <table> <tbody id="taskform:_id2:tbody_element"></tbody></table> <hr /> <input id="taskform:transitionButton" name="taskform:transitionButton" type="submit" value="Save and Close Task" onclick="clear_taskform();"/> <hr /> <input id="taskform:_id9" name="taskform:_id9" type="submit" value="Save" onclick="clear_taskform();"/> <input id="taskform:_id10" name="taskform:_id10" type="submit" value="Cancel" onclick="clear_taskform();"/> ...
