Multiple AJAX label components are not returning the expected data consistently
The AJAX label component has a dependency on the data sources providing the label data. Specifically, if this component uses Subdialog components as a data source, or other data sources that require time to collect and return the data sets required to populate, the AJAXLabel component must be configured with sufficient time to return the data, but not longer than 90 seconds.
A simple workaround is to replace the AJAX label components with ASCIIMerge Label components.
