Creating or viewing a work item results in a blank page and not an object error with RTC 4.0.4
This technote provides information about an issue that can occur after upgrading to IBM Rational Team Concert (RTC) 4.0.4 where attempts to open or create a work item results in an error: "'this.$.currentStyle' is null or not an object".
When opening work items or creating a new work item, a blank page and the following error is displayed in the Web User Interface (UI).
'this.$.currentStyle' is null or not an object
In the RTC eclipse client, the work items can be opened and new work items can be created.
There are deprecated presentations in the work item editor presentation. There are attributes of type HTML that have a string presentation or there are attributes of type string that have an HTML presentation.
This is a known defect in RTC 4.0.4, filed under APAR PM98897 and further detailed in Jazz Work Item Fix handling of deprecated presentations in migration to new widgets (283200)
As of RTC 4.0.4, HTML attributes can only have HTML presentations and String attributes can only have String presentations. Incorrect pair matchings will show warnings in the editor presentations process editor in the RTC Eclipse client and are marked as deprecated presentation (see the screen shot below). This warning will prevent work items using the affected editor presentations from creating or displaying in the web client. These presentations were marked as deprecated but backward compatibility is still an issue in 4.0.4. This has been fixed in the 4.0.5 release.
See the following details for a list of deprecated presentations in 4.0.4:
Deprecated presentations for string attributes
Deprecated presentations for html attributes
