Hello!

I try set value of enumeration type of Work Item on pre-condition on server-side plugin according this post , but I need to save a value of list. <o:p> </o:p>

I use IBM RTC 5.0.2. <o:p> </o:p>

If I understood correct, I need set value by workItem.setValue(IAttribute attr, Object val), where workItem is IWorkItem, and val is Identifier (for Enumeration Type of attribute). <o:p> </o:p>

I have found needed attribute, but I don't know, how found needed Identifier value (I have a text display name of needed value, or literal-link as simple text (String).) <o:p> </o:p>

Use this code to found needed Identifier, but when I try to get Enumeration (enumeration = (Enumeration) enumerationService.resolveEnumeration(attrHandle); ) - my plugin falling down. <o:p> </o:p>

public Identifier getVaLByString(String strVal, IAttribute attr, IWorkItem wi) { <o:p> </o:p>

IAttributeHandle attrHandle = getAttrHandle(attr, wi); <o:p> </o:p>

EnumerationService enumerationService = new EnumerationService(); <o:p> </o:p>

Enumeration enumeration = (Enumeration) enumerationService.resolveEnumeration(attrHandle); //FAIL, Plugin Falling down <o:p> </o:p>

// Enumeration enumeration = (Enumeration) enumerationService.resolveEnumeration(attr); // FAIL TOO! <o:p> </o:p>

List literals = enumeration.getEnumerationLiterals(); <o:p> </o:p>

<o:p> </o:p>

for (Iterator iterator = literals.iterator(); iterator.hasNext();) { //literalsParse <o:p> </o:p>

ILiteral iLiteral = (ILiteral) iterator.next(); <o:p> </o:p>

if (iLiteral.getIdentifier2().getStringIdentifier().equalsIgnoreCase(strVal)) return iLiteral.getIdentifier2(); <o:p> </o:p>

} //literalsParse <o:p> </o:p>

return null; <o:p> </o:p>

} <o:p> </o:p>

private IAttributeHandle getAttrHandle(IAttribute aT, IWorkItem wI) throws TeamRepositoryException { //getAttrHandle_WORK FINE! <o:p> </o:p>

IAttributeHandle out = null; <o:p> </o:p>

<o:p> </o:p>

List<IAttributeHandle> listHandle = wI.getCustomAttributes(); <o:p> </o:p>

IAttribute cA = null; <o:p> </o:p>

<o:p> </o:p>

for (IAttributeHandle cHandle : listHandle) { <o:p> </o:p>

IRepositoryItemService itemService = getService(IRepositoryItemService.class); <o:p> </o:p>

cA = (IAttribute) itemService.fetchItem(cHandle, IRepositoryItemService.COMPLETE); <o:p> </o:p>

<o:p> </o:p>

if (cA.equals(aT) || cA == aT || cA.getDisplayName().equals(aT.getDisplayName())) <o:p> </o:p>

return cHandle; <o:p> </o:p>

} <o:p> </o:p>

<o:p> </o:p>

return out; <o:p> </o:p>

} //getAttrHandle <o:p> </o:p>

A lot of examples uses Client library, but it doesn't work on server-side. <o:p> </o:p>

Pavel,

first, you should never set a work item attribute in a precondition.

The purpose of preconditions is to evaluate whether the current action can be performed or not, by reading attribute values.

If you want to set an attribute value, write a follow-up action instead.

Concerning your specific issue, I would rather retrieve a IEnumeration object than an Enumeration one.

I always use this code for retrieving enumerations, and it works fine:

IProgressMonitor monitor = new NullProgressMonitor();

IWorkItemCommon workItemCommon = pluginAbstractService.getService(IWorkItemCommon.class);

IEnumeration<?> enumeration workItemCommon.resolveEnumeration(attributeHandle, monitor);

Anyway, if you have a close look at my original post, you will find that I am using the "internal" Enumeration class to add an enumeration value to db-based enumeration at runtime (i.e., as the plugin is running).

If I understand, you need to set the value of a work item attribute to an already existing enumeration value.

What is pluginAbstractService in line IWorkItemCommon workItemCommon = pluginAbstractService.getService(IWorkItemCommon.class);?

If it my plugin AbstractService, and I can describe as this.getService(IWorkItemCommon.class) - it fallin down plugin. Whats other way to become IWorkItemCommon workItemCommon?

import com.ibm.team.repository.service.AbstractService;

// where plugin=your plugin's class

AbstractService pluginAbstractService = (AbstractService) plugin;

Actually, this code snippet is in another class (named "PluginUtility") than my plugin's class; I pass the plugin object (from inside the plugin's class) this way:

PluginUtility utility;

utility = new PluginUtility(this);

Then, in PluginUtility:

public PluginUtility(Object currentPlugin) {

plugin = currentPlugin;

}

.....

AbstractService pluginAbstractService = (AbstractService) plugin;

AbstractService is only available if the extension point implementation class extends AbstractService as it should.
