Parameter name appears NULL when passing from AutoComplete
SA-10453
Summary
You, as an application developer, use the OOTB 'AutoComplete' format in a section with the DataSource set to 'Activity'. When you assign a property (for example: [.test]) under parameter textbox and run it, the value is generated on the Clipboard but not observed in tracer.
Steps to Reproduce
1. Create a section with autocomplete and input activity and params in to it..
2. Run it to observe that there is a NULL value in tracer.
Root Cause
The root cause of this problem is a defect in custom application code/rules. No editable control is bound to the property that is being passed to Autocomplete activity.
Resolution
This issue is resolved through the following Local-change:
Drop "HiddenValue" control anywhere in the section and bind it to the property that is getting passed to the autocomplete activity. Use [.propertyname] syntax in autocomplete configuration.
