get custom attribute on precondition use java
I'm newer on RTC API and Plain Java.
I try to get some values of custom attributes in saved work item. RTC get this exception "Exception checking recondition.
An unhandled exception occurred during "<my_precondition_plugin_name>".
org.eclipse.emf.ecore.util.EObjectResolvingEList$Unsettable incompatible with com.ibm.team.workitem.common.model.IAttributeHandle."
I need make server-side plugin. First time I try get all names of custom attributes in "For"
long list_count = workItem.getCustomAttributes().size();
for (long inx=0; inx < list_count; inx++) {
int i = (int) inx;
com.ibm.team.workitem.common.model.IAttributeHandle wi_c_handle = workItem.getCustomAttributes().get(i);
...
}
then I try code of example:
com.ibm.team.workitem.common.model.IAttributeHandle wi_c_handle = workItem.getCustomAttributes().get(0);
but RTC request some exception.
full code is here (output on file - it's some kind of "debug" and "watch"):

I would like to suggest you get started here: https://rsjazz.wordpress.com/2015/09/30/learning-to-fly-getting-started-with-the-rtc-java-apis/ . Follow it and do the workshop. Don't do it with 6.0.2 because the SDK 6.0.2 currently has a problem.
Look at the references posts about how to work with work item attributes in the client API. See https://rsjazz.wordpress.com/2013/01/02/working-with-work-item-attributes/ and https://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/ for some hints for the client and server work item API. Note, there is pretty much no difference in the client and server API when getting attributes. Use IWorkItemCommon.findAttribute(,attributeID as String,) or iterate the custom attributes and take the one you want. There are many examples on the blog that should get you going. Note, you can download the code of many of the examples from there too. |
