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

[oliverweidel]

Hello,

is there something new in Explorer2 in relation to the forms?

In Activiti 5.6 (in the Explorer) the form was succesfully displayed but in Activiti 5.7 the form is not displayed. The same JAR, the same BAR - no changes.

Form:

<h1>Neuen Tweet erstellen</h1>

<p>
  <b>Ihre Email-Addresse: </b>
  <input type="text" name="email" value="" />
  <input type="hidden" name="email_required" value="true" />
<p>

<p>
  <b>Welchen Twitter Account moechten Sie verwenden:</b><br/>
  <select id="classificationBox" name="twitterAccount">
    <option value="Value1">Activiti BPM</option>
  </select>
  <input type="hidden" name="twitterAccount_required" value="true" />
</p>

<p>
  <b>Ihr Tweet-Vorschlag:</b><br/>
  <textarea name="content" value=""></textarea>
</p>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Also the process is not executable. I received this error message:

Any idea whats wrong? The same JAR and BAR files are deployed…

Regards, Oliver

[jerrythejerry]

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

[slaimankoeik]

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

[jbarrez]

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??)
