Form properties not initialized when null or empty

Hi,I have a question regarding form properties. When using form properties and the user did not fill in a value, the process variable related to the form property is not set in the execution. You can see this in the FormPropertyHandler on line103 :if (modelValue != null) {…set variable in execution}

We have chosen this approach because, in theory, a null-variable is the same as a variable not being present, from an API-perspective. When calling getVariable() an inexistent and null-value variable will both return null. However, we didn't take into account that expressions throw exceptions when a variable is present, opposed to when it's null.

It indeed makes more sense to say that, when you explicit ally define a form-property, null-values should be stored as well. One wouldn't declare a property and not use it later on…

Create issue for this, see https://jira.codehaus.org/browse/ACT-1499
