Hi!
I have a Workflow W and a form F.
F has a only field value (f1). F is into workflow W.
W has a variable (var1).
I need to pass de field value "f1" to "var1". Which is the best form to pass, because I have tried it but always var1 results "null"
Thanks for all.
One of the possible reasons for getting a null value is probably you missed to add 'Base Context' to the form. To access a variable from a form to a workflow, Base Context has to be set.
The workflow Flex has a variable (ses) and form Flexo has a field (processInputs.ses). In field set to ":display.session" and I need to pass this value to variable "ses" in workflow.
This is the code from workflow and form, I have tried with base context, with processInput, but nothing, it follow prints "null"

I couldn't exactly make out what u need from the code but I have changed a bit of the code you have sent me, where the user is prompted to enter value of f1 in a form and is set to var1 in the taskdef.
Pasting the sample code below. You don't need to use basecontext as the form is placed in the taskdef itself.
<TaskDefinition name='Flex' l taskType='Workflow' executor='com.waveset.workflow.WorkflowExecutor' suspendable='true' syncControlAllowed='true' execMode='sync' execLimit='0' resultLimit='0' resultOption='delete' visibility='runschedule' progressInterval='0'>
<Form name='Flexo'>
<Display class='EditForm'/>
<Field name='f1'>
<Display class='Text'>
<Property name='title' value='Enter F1'/>
</Display>
</Field>
</Form>
<Extension>
<WFProcess name='Flex' maxSteps='0'>
<Variable name='ses' input='true'/>

Hope this helps,

Hi!
Thanks for all to you. Your code have helped me. Now I know what's the problem. I've got a object ":display.session" as expansion value in the field form,
and this object always is null when arrives to workflow.
With another type value like could be a string has not problems to pass the value from form to workflow.
is there any problem with objects (:display.session, etc.) when it 's passed from form to workflow?
THANKS, THANKS, THANKS.
