Hi,

I’m using bonita 7.2.3. I created a custom widget, to obtain a table with a column that contains checkboxes to get row selected. I created also in the form page a JSON variable to collect values checked in the table. The variable is correctly populated and on page submit I need to transfer those values to a process variable (the type is java.util.List) I defined in the process.  
Contract variables can’t be defined as List, so how can I pass values from page to variable? Using a text contract variable, I obtain an error message as JSON cannot be assigned to TEXT.

Any suggest would be appreciated.  
Thank you

I solved my problem.  
The way is to pass JSON as string.  
In formOutput it can be done by using **JSON.stringify($data.myJsonData)**

Sorry for answering later… i was busy at work

Im with this code so far:

```
<div class="table-responsive">
<table class="table table-striped">
    <thead>
        <tr>
            <!--<th></th>-->
            <th class="ng-binding ng-scope" ng-repeat="header in properties.headers"> {{header}}</th>
        </tr>
    </thead>
    <tbody class="ng-scope">
        <tr class="ng-scope" ng-repeat="row in properties.content">
            <!--<td><input type="checkbox" class="checkbox"/></td>-->
            <td class="ng-binding ng-scope" ng-repeat="column in properties.columnsKey track by $index">{{column}}</td>
        </tr>
    </tbody>
</table>
</div>

```

Problem: i really cant get the data into the rows, im doing something wrong with the column keys and content input, what am i doing wrong?
