Hi,

The old forms are not supported anymore in the new Activiti Explorer.
You should use the form properties that can be configured on the user task and start events.
You can read more about it in the userguide.

Best regards,

Are there plans to add to Activiti 5.7 the feature to use external HTML forms as demonstrated in the Screencast: from zero to executable process with the Activiti Designer?

Thank you.

Hi,

No the external HTML forms were the old way of building tasks Forms with Activiti, so < 5.7.
From 5.7 on we'll use the form properties that the Activiti Explorer 5.7 is also using.
Of course there's the possibility to build the external form rendering yourself as explained in the userguide.

Best regards,

Ok, thank you!

I resolved it this way:

    <startEvent id="startevent1" name="Start" activiti:initiator="employeeName">
      <extensionElements>
        <activiti:formProperty id="email" name="E-Mail-Adresse" type="string" required="true"/>
        <activiti:formProperty id="tweet" name="Tweet-Vorschlag" type="string" required="true"/>
      </extensionElements>
    </startEvent>

    <userTask id="usertask1" name="Review Tweet" activiti:assignee="kermit">
      <documentation>${employeeName} moechte gerne folgenden Tweet veröffentlichen: ${tweet}.</documentation>
      <extensionElements>
        <activiti:formProperty id="publishOnTwitter" name="Publish on Twitter" type="enum" required="true">
         <activiti:value id="true" name="Ja" />
         <activiti:value id="false" name="Nein" />
        </activiti:formProperty>
        <activiti:formProperty id="comment" name="Kommentar" type="string" required="false"/>
      </extensionElements>
    </userTask>

But now Im facing a new error:

The JAR file was exported manually with manifest information and was copied into the activiti-5.7\apps\apache-tomcat-6.0.32\webapps\activiti-rest\WEB-INF\lib folder.

The deployment of the BAR file was successfully (within Activiti Explorer) and Im able to start an instance of the process.

Any idea why I got the Class not found exception?

Thanks in advance,

Oliver

Hi,

To get it working for the Activiti Explorer you should copy the JAR to activiti-explorer/WEB-INF/lib.

Best regards,

Hi, thank you - it works!

Is this new in Activiti 5.7 Explorer2 that I also have to copy the JAR to activiti-explorer/WEB-INF/lib?

I do not see the start form in Activiti Explorer 5.7.

I deployed the .bpmn20.xml and the .forms files using Explorer (Manage/Deployments/Upload New) and saw:

    LoanRequestProcess.bar
    Deployed 2 hours ago

    Process Definitions

    Process to handle a loan request
    startFormtest

    Resources

    LoanRequestProcess.bpmn20.xml
    LoanRequestProcess.png
    diagrams\handleLoanRequest.form
    diagrams\loanRequest.form
    startFormtest.bpmn20.xml

The Process (LoanRequestProcess.bpmn20.xml) has the following:

<process id="loanrequest" name="Process to handle a loan request">
    <documentation>Process for requesting a loan from Sharks (from diagram).</documentation>
    <startEvent id="theStart" name="Start" activiti:formKey="diagrams\loanRequest.form" activiti:initiator="fozzie"></startEvent>
    <scriptTask id="checkCredit" name="Check Credit" scriptFormat="groovy">
      <script><![CDATA[outrintln "Checking credit for " + name;
creditCheckOk = false;
if( (income / 2 ) > loanAmount)
{
creditCheckOk = true;
}
outrintln "Credit checked for " + name + " outcome is " + creditCheckOk;]]></script>
    </scriptTask>

The loanRequestForm has:

<h1>Loan Request</h1>
<table>
<tr>
<td>
   <label>
    Name:<br/>
    <input type="text" name="name" value="" />
    <input type="hidden" name="name_required" value="true" />
    <input type="hidden" name="name_type" value="String" />
   </label>
</td>
</tr>

The form does not display, so I click on the Start Process button in Explorer. That displays another screen that has the heading
"Process to handle a loan request" and has a Start Proces button and a Cancel button. I click the Start Process button and see a red
exclamation mark.

I get an exception:
Cause: org.activiti.engine.ActivitiException: problem evaluating script: javax.script.ScriptException: groovy.lang.MissingPropertyException:
No such property: name for class: Script2

It appears to me that the Start form is not displaying and the script task therefore cannot find one of the variable set by the form.

I know this must be something really simple since everywhere I look, people seem to be using Start Forms.

Any suggestions?

I think the answer is in this topic… something like 'old forms are not supported anymore' etc…

c'mon guys - at least glance at the userguide before starting threads. :mrgreen:

- The old forms are not supported anymore in the new Activiti Explorer
- userguide : http://www.activiti.org/userguide/index.html
- form properties : http://www.activiti.org/userguide/index.html#formProperties
- external form rendering : http://www.activiti.org/userguide/index.html#externalFormRendering

Hello,
first question:
is there a way to display form in eclipse instead of activiti explorer ?

Re: [Resolved] Forms in Activiti Explorer 5.7 are not displayed!

jbarrez — Mon, 04 Apr 2016 11:58:07 GMT

No. Eclipse is the dev environment and the rendering env is in the web UI.
There is no 'preview' functionality for forms.

(also: why resurrecting a thread from 2011??)
