Support added for expression in strategy scorecards
Resolved in Pega Version 8.2.8
When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

Oracle database performance improvements
Resolved in Pega Version 8.2.8
When the IH Summary was enabled and materialized on an ADM model, updating the ADM model was very slow on large sites. This has been resolved by adding several performance improvements for working with Oracle databases, including Oracle pre/post processing steps.

Handling added for Oracle Aggregate IH Summaries
Resolved in Pega Version 8.2.8
When using using (Non Materialized) IH Summaries to aggregate IH data, the data returned by the IH summary did not include all the expected records. If the same criteria was executed on the database via SQL or by using a strategy to process raw IH data then the results were as expected. This was due to a difference in handling of Oracle vs postgres which causes an order by clause not to be generated in the query: the postgres column name is lower case, while in Oracle it is upper case. This has been resolved by updating the system to get the column name correctly from the propertytocolumn map so IH records are returned in correct order by Browse By Keys operation.

Data Flow correctly saved to Database table Dataset
Resolved in Pega Version 8.2.8
After setting up a dataflow with Report definition as a source and Database table dataset as destination with the option "Insert new records and override existing", a data transform was used to modify a few of the values and write to the same database table. This table was mapped to pegadata schema and didn't have a pzpvstream column. Running the data transform generated an exception stating "DataStoreSaveStatementWithoutStream(PageDatabaseMapperImpl). The error was not seen when the pzpvstream column was added or if pzInskey was also removed along with pzpvstream, or if "only insert new records" was selected. This was traced to pzInsKey and pxInsName being null in the query formed while writing. There are two execution paths for the database dataset save operation, one for internal tables and another one for external tables. For a table with pzInskey but no blob, the system was incorrectly using the external table logic. This has been corrected.

Exported Excel from Decision Table wraps correctly
Resolved in Pega Version 8.2.8
After upgrade, entries were displayed in a single line on exporting a decision table to Excel despite WrapText cell formatting being set. This was traced to the WrapText cell formatting set under the UpdateGridCells() function being overridden inside an addDataFormat() function callas part of DecisionTableWorkBookConverter.java. This has been resolved by adding the new function "setWorkAreaCellStyles" and calling it after generateWorkbook() function call of super class (AbstractWorkBookConverter.java).

Filter by Rule Resolution enabled for GetPegaExpressFieldsByType
Resolved in Pega Version 8.2.8
After creating a Text Input property of type none in a ruleset version [For ex: Myruleset:01-01-01] and then saving this property in a higher ruleset [Myruleset:01-01-02] and changing the type to promptlist, the same property appeared twice in Eligibility Builder [Content -> Offers -> Eligibility Builder]. This has been resolved by enabling the "filter by rule resolution" option in the Rule-Obj-Property.pzGetPegaExpressFieldsByType report definition to make sure rules are fetched from the latest ruleset version only.

Report definition performance improvement
Resolved in Pega Version 8.2.8
Performance issues were seen with the pzOperatorsByWorkGroup report definition. This was traced to the report definition is adding an UPPER function for edit filter properties which caused it to take more time to run when combined with an ignore case check in the filters of the Report Definition. This has been corrected.

Tracer toolbar shows correctly in Microsoft Internet Explorer
Resolved in Pega Version 8.2.8
After upgrade, the developer toolbar for the tracer pop up was not visible in Internet Explorer. Investigation showed that IE was loading the correct elements, but they were not displaying due to recent updates made to prevent Cross-site scripting vulnerabilities for the tracer. This has been resolved.
