Is it possible to add/create new history token from every class? I have the problem, that i get NullPointerException if i try to create new token (History.newItem("infoTab")) outside the main class (the main class contains the onModuleLoad() method). Here the error message:
09:45:11.890 [ERROR] [com.mycompany.client.AdminInterface] Unable to load module entry
point class com.mycompany.client.entries.MainEntry (see associated exception for details)
edit: the iframe part was not added in the index.html. After adding it, i get following:
11:16:48.885 [ERROR] [com.mycompany.client.AdminInterface] Error while executing the JavaScript provider for property 'user.agent'

so i can't really understand, what is wrong...whithout the iframe i get five history tokens added successfully as follow http://localhost:8080/client/index.html#token1.
It works with and without the iframe tag in my index.html. My mistake was, that i use the url query parameters wrong...after the # :)

I'm using Slick in Akka to access MySQL DB.
I want to get the table column info by calling resultSet.getMetaData, as shown below:
(I tried with slick.jdbc.meta.MTable.getTables, but it always returns an empty vector; as someone else also ran into it.)
implicit val meta2string = GetResult{ row: PositionedResult =>
val md = row.rs.getMetaData() // call rs.getMetaData will cause exception thrown
"debugging"
}
val done = Slick.source(sql"SELECT * FROM trips".as[String](meta2string)).runForeach(println)
The problem is, when ever I call rs.getMetaData(), an exception will occur:

I'm not sure if there's sth. wrong with my use, or it's not supported by Slick?
Could anyone please help me on this?
I'm not quite sure of this, but I suspect this issue is due to that I was running the code example in sbt console.
I ran the same code snippet with a jar and everything was fine.
Help is needed with a code example for proper understanding of setting parameters in own RUTA script.
In my case I need to setup the configuration parameter "emptyIsInvisible" to false. The root cause is described in Are some extra settings in RUTA script needed to detect annotations with the same begin and end attributes?
I made two attempts
1) use the name of standard Ruta Engine:
ENGINE BasicEngine;
Document{->CONFIGURE(BasicEngine, "emptyIsInvisible" = false)};`
That part of the script does not change the default settings.
2) use the name of own engine:
ENGINE xxx.yyy.zzz.TagEngine;
Document{->CONFIGURE(TagEngine, "emptyIsInvisible" = false)};
In that case the script raises the following exception:

This parameter will not solve the problems in the linked question. The parameter controls the basic matching if there are no annotations at all at some positions. This means that is will only affect the matching if a different seeding is applied, e.g., there is no seeding.
Concerning this question:
You cannot configure the RutaEngine analysis engine within the script the analysis engine tries to execute. You need to set the configuration parameter on framework level. This depends on how you create and run the UIMA analysis engines in your code.
In a simple Ruta project, you need to modify the template analysis engine description (BasicEngine.xml) so that the generated descriptions will contain the parameter value.
Using uimaFIT or other factory methods, you need to pass the parameter and its value when creating the description or analysis engine.

This is happening when I try to insert a new Tracking Object into the DB like so :
Tracking tp = new Tracking()
tp.setUser(user)
nowCal.add(Calendar.MINUTE,i++)
tp.setCreated(nowCal.getTime())
tp.setSpeed(10f)
tp.setLocation(new Point(points[1],points[0]))
tp.save(flush:true)
user.addToTracking(tp);
And my Tracking class is defined as so :
import grails.mongodb.geo.Point
class Tracking {
Point location
Date created
float speed
static belongsTo = [user:User]
static constraints = {
speed nullable:true
}
static mapping = {
location geoIndex:'2dsphere'
}
}
I really can't see what the problem is here, I Think I've defined everything correctly as it shows in the GORM documentation : http://gorm.grails.org/latest/mongodb/manual/#geoSpatial
The other thing is this code works perfectly well when running in non prod mode.
so executing grails run-app works but grails prod run-app doesn't..
Any help would be much appreciated.
Thanks

I had the same issue, and after two days of debugging finally found a workaround.
The problem was caused by the following:
There is a Grails utility class called org.grails.datastore.mapping.reflect.FieldEntityAccess, apparently used to access entities fields using reflection. That class has an inner class called FieldEntityReflector. Every time a FieldEntityAccess instance is created, there is an instance of FieldEntityReflector created internally. All those instances are stored in a static map called REFLECTORS, whose keys are the entity names, apparently for performance reasons.
During bean initialization, mongoDatastore bean creates one FieldEntityAccess for each entity, passing a DocumentPersistentEntity as constructor parameter.
In the same way, grailsDomainClassMappingContext bean, unaware of mongoDatastore creates its own FieldEntityAccess for each entity, passing down KeyValuePersistentEntity as parameter. Those FieldEntityAccess instances and their corresponding EntityReflectors are unaware of mongo and therefore don't support mongo specific types like Point.
Given that the REFLECTORS map keys are entity names, EntityReflectors created last for the same entity, override previously created reflectors, and are used by all EntityReflector instances.
When grailsDomainClassMappingContext reflectors are created last, they are used when mongo tries to persist and entity and therefore throw an error.
In short, the error is thrown when grailsDomainClassMappingContext bean is initialized after mongoDatastore bean.
In development mode, UrlMappingsGrailsPlugin plugin creates some beans used to allow url mappings reloading. Those beans trigger instantiation of grailsDomainClassMappingContext bean before mongoDatastore bean. As the mongo beans are created later, the error is not thrown. But, in production mode, those beans are not created, and mongoDatastore is created before grailsDomainClassMappingContext, therefore throwing the error.
Potential solutions
Force grailsDomainClassMappingContext bean instantiation before mongoDatastore: I was unable to do that after several attempts, maybe because of grails bean instantiation logic.
Force UrlMappingsGrailsPlugin instantiation even on production mode: I prefered not to go that way due to possible permformance implications.
Use the static method clearReflectors of FieldEntityAccess class to clear all the reflectors after system initialization:** I decided to do that and the system started to work. I haven't tested it in depth, but was able to persist Point correctly.
In order to call the method, I created a bean depending on both grailsDomainClassMappingContext and mongoDatastore and called FieldEntityAccess.clearReflectors()
package app.utils
import org.grails.datastore.mapping.mongo.MongoDatastore
import org.grails.datastore.mapping.reflect.FieldEntityAccess
import org.grails.datastore.mapping.model.MappingContext
class MongoDatastoreHolder {
MongoDatastore mongo
MappingContext context
MongoDatastoreHolder(MappingContext context, MongoDatastore mongo) {
this.context = context
this.mongo = mongo
FieldEntityAccess.clearReflectors()
}
}
And defined that bean in resources.groovy:
import app.utils.MongoDatastoreHolder
beans = {

}
Hope it helps, and sorry for my bad english, this is my first StackOverflow answer.
I have Eclipse Oxygen with Java. I can refactor some variables but since I updated to Java 9 it can no longer refactor some names like interface's methods, but it can refactor other kind of names or variables. It yields this internal error in the error log:

It just renames but immediately undo the refactor operation.
This looks like Eclipse bug 525842.
The fix for this bug is currently scheduled to be in Eclipse Oxygen.3a (4.7.3a) due to be released on 11th April (2018).
It may be a bug in Eclipse. I have the same problem but I found a solution/workaround:
select the interface which contains the method you want to rename and press F4 to display
the Type Hierarchy of the interface.
In the Type Hierarchy you will see in the bottom pane all the methods of your interface.
Select the one you want to rename, right click on it, and do the refactor-rename.
For me it renamed all the implementations of this method.
I am using selenium Webdriver for the testing web application. I am using marioette driver for the same as I am havin firefox 48.0 since yusing the same the web page gets open however I am not able to put the values in the text box it gives the error " java.lang.NullPointerException"
I have written code
#BeforeTest
public void setUp() throws Exception {
System.setProperty("webdriver.gecko.driver", "D:\\ashwini\\geckodriver.exe");
driver= new MarionetteDriver();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void testAddAccount() throws Exception {
driver.get("http://qa.luna.wexeurope.com/CPCardWeb/login.htm?programme=CPYCGB");
driver.findElement(By.id("username")).clear();
driver.findElement(By.id("username")).sendKeys("cp_admin");
}
#AfterTest
public void teardown()
{
driver.quit();
}
Output is:
1472448949884 Marionette INFO sendAsync 3744f8a9-772e-42fe-8c85-6f9964888fb1

I have checked the same it gives null values in sendkeys.
However instead of by.id I have used other options like name, xpath, css selector for the same
it gives the error only.
Value is still not inserted in the text box
Line no 36 is
driver.findElement(By.id("username")).clear();
driver.findElement(By.id("username")).sendKeys("cp_admin");
I have debug that as you said, Yes it passes the null value to the element that's why it throws null pointer exception. so please let me know to solve this. as I have tried to pass values using the id, name, xpath, css selecter. same error is displayed. so could u please help me?
NullPointerException means your driver is not initialized properly and hence it has null value when it tries to find a element. This is not related to xpath/id etc.
Please check line number 36 of Add_Account class you will get to know where exactly there is an error. It will be good if you put whole code of your class for anyone to look into.
issue is resolved by removing unwanted jar from the referenced library
