includes process definition and 2 screenshots (of faulty behavior and temporary workaround)

Description of problem:
When you generate a task form, for a task that has datainput assigned to the constant value (variable is equal to "constant")
The final form includes
<label for="name">variable</label>
                            		<div class="div_checkbox">
                              		<![CDATA["constant"]]>
</div>

This is being interpreted as HTML comment, therefore constant value is not being displayed in generated task form.

How reproducible:

Steps to Reproduce:
1) Download attached process (you need to have human task with datainput assignment to constant value, i.e. datainput is equal to "constant")
2) generate task form in web designer
3) deploy process via Guvnor
4) Start process in business-central
5) Submit the form
6) proceed to assigned task for a user, and you will now see, that the datainput value is empty (constant value should be displayed) - as shown in attached screenshot snap.tff

Actual results:
when datainput has assignment to constant value, value is not displayed

Expected results:
value should be displayed
