Form Customization

[hmartim]

Hi,

How could I customize a form associated with a User Task?

Supose I want to execute some fields validation before complete the task, or I want to add a button that, when clicked, shows a support information to the user. Is form event model based  on JSF, so I should customize the associated class with event handlers?

Will the Explorer recognize this customization?

Sorry for my english.

regards,
Hudson

Hi,

This is currently not supported in the Activiti webapps in a "proper" way but sure sure is something that we need to provide.
You could do the following hack for and put the following html & inline-javascript code in your form:

<div>
   <a href="#" onclick="javascript: var si = document.getElementById('support-info'); si.style.display = (si.style.display == 'none' ? 'inline' : 'none');">Support Information</a>
</div>
<div id="support-info" style="display: none;">
   Here comes the the support information
</div>

You could also include a <script> block in your form template that "might" get triggered, the reason I say "might" is because some browsers will execute the <script> code and some will not. I will add the possibility to use the <script> blocks in all browsers to my things to do.

To hook into the validation mechanism on the client is not possible without performing a serious hack which I wont even try, it is however also something that we should take a look at.

PS. We are NOT using JSF as the web framework which we have built the Activiti webapps on, instead Spring Surf is used: http://www.springsource.org/extensions/se-surf

Thanks for the client example.

There is also a need on server validation and suplementary server bussiness processing. So is possible in Explorer a pluggable rendering service that could be implemented with JSF, Wicket, …, or it is not the right way?

Hi,

Is using JSF is mandatory? You may consider Grails with Activiti plugin project at http://code.google.com/p/grails-activiti-plugin/.

Explorer does not have a pluggable rendering service.
However, Explorer (and Probe), use a REST-API that you can use in your own application: http://activiti.org/userguide/index.html#N10B1F

Thanks for all info.

I will analyze each suggestion to identify the faster way to adopt Activiti as our BPM suite.

Ressurecting a thread from 2010 … wont probably trigger an answer.

The idea is simple: Activiti  has a formService. In JSF, get the form properties through the FormService. Put them on a backing bean or whatever it is called in JSF (been 6 years since JSF for me luckily). Have a dynamic form rendering based on the types in the properties. When clicking the button, pass the values again in the formService.submit
