Hello, i’m trying to create a bp start screen, that will only ask for a comment, and automatically set current user for a first user task (set current user as a procRole). My controller looks like this:
package ru.company.myproject.web.bpm.screens
import com.google.common.base.Strings
import com.haulmont.bpm.entity.ProcActor
import com.haulmont.bpm.entity.ProcRole
import com.haulmont.bpm.exception.BpmException
import com.haulmont.bpm.form.ProcFormParam
import com.haulmont.bpm.gui.form.standard.StandardProcForm
import com.haulmont.cuba.core.global.DataManager
import com.haulmont.cuba.core.global.LoadContext
import com.haulmont.cuba.core.global.Metadata
import com.haulmont.cuba.gui.components.TextArea
import com.haulmont.cuba.gui.data.CollectionDatasource
import com.haulmont.cuba.security.entity.User
import com.haulmont.cuba.security.global.UserSession
import javax.annotation.Nullable
import javax.inject.Inject
import javax.inject.Named
class ProcFormStart extends StandardProcForm {
@Named("procActorsFrame.procActorsDs")
private CollectionDatasource<ProcActor, UUID> procActorsDs
@Inject private DataManager dataManager
@Inject private Metadata metadata
@Inject private UserSession userSession
@Inject protected TextArea comment
@Override
void init(Map<String, Object> params) {
super.init(params)
// comment.setRequired(true)
ProcFormParam procRoleCodeParam = formDefinition.getParam("bpmRoleName")
if (procRoleCodeParam == null || Strings.isNullOrEmpty(procRoleCodeParam.getValue()))
throw new BpmException("procRoleCodeParam is not defined")
String procRoleCode = procRoleCodeParam.getValue()
ProcRole procRole = findProcRole(procRoleCode)
if (procRole == null)
throw new BpmException("Process role with code " + procRoleCode + " not found")
String currentLogin = userSession.getUser().getLogin()
LoadContext ctx = LoadContext.create(User.class)
.setQuery(LoadContext.createQuery('select u from sec$User u where u.login = :userLogin')
.setParameter("roleName", currentLogin))
User user = dataManager.load(ctx)
ProcActor procActor = metadata.create(ProcActor.class)
procActor.setProcInstance(procInstance)
procActor.setUser(user)
procActor.setProcRole(procRole)
procActorsDs.addItem(procActor)
}
@Nullable
private ProcRole findProcRole(String procRoleCode) {
LoadContext ctx = LoadContext.create(ProcRole.class)
.setQuery(LoadContext.createQuery('select pr from myproject$ProcRole pr where pr.code = :roleCode')
.setParameter("roleCode", procRoleCode))
ProcRole procRole = dataManager.load(ctx)
return procRole
}
And so as I click Start Process, istead of getting my window with a comment and attaching myself as an actor - i get an exception
java.lang.IllegalArgumentException: MetaClass not found for mobdekbkp$ProcRole
