Installation
This release note applies to you if you are upgrading to 1.5.2 from a computer running an earlier version of the i2b2 workbench. This release contains only changes to the i2b2 Workbench so it is not necessary to update the server. The 1.5.2 client will continue to work with the 1.5.1 server.
Fixes
i2b2 release 1.5.2 contains the following fixes to the i2b2 Workbench.
Timeline: Value constraints not always in the XML request message.
The value constraints for numeric type tests were not being sent correctly in the XML request message. The <constrain_by_value> section was not generated. As a result all values were appearing in the timeline.
STATUS/RESOLUTION: This issue has been resolved. The value constraints for numeric type concepts are now sent in the XML request message correctly. Only those concepts meeting the criteria will display a "tick" in the timeline view.
Timeline: Value constraints for enumerated text returns error.
The value constraints for enumerated text were returning an error because the operator of "Is" was being sent with the text value. In addition, the text value was missing single quotes which resulted in the error message. As a result all values were appearing in the timeline.
STATUS/RESOLUTION: This issue has been resolved. The value constraints for text type concepts (enumerated) are now sent in the XML request message correctly. Only those concepts meeting the criteria will display a "tick" in the timeline view.
Timeline: Value constraints using "BETWEEN" clause not always correct in the XML request message.
Value constraints using the "BETWEEN" clause where not always correct in the XML message. The <value_operator> was missing and the value was not populating the <value_constraint>. As a result all values were appearing in the timeline.
STATUS/RESOLUTION: This issue has been resolved. The value constraints using the "BETWEEN" clause are now sent in the XML request message correctly. Only those concepts meeting the criteria will display a "tick" in the timeline view.
