Re: GWT Delevoper Plugin for Chrome must be installed from Web Store

I just hit the same issue. When I went to chrome://extensions/ it said it was installed and enabled. I just disabled it and reenabled it and it started working again.

Re: Super Dev Mode with multiple source folders

Thanks Thomas! I will try.

Cheers,

Simply pass multiple -src arguments: "-src src/main/java -src target/generated-sources/gwt"

Hi folks,

I have a doubt with Super Dev Mode. I have a maven project that generate some sources in a target/generated-sources/gwt. I want to add this folder to the codeserver, but I see that only one folder I can add by parameter:

CodeServer [-bindAddress address] [-port port] [-workDir dir] [-src dir] [module]

Is possible to use more than one folder to the CodeServer?

Thanks,
Juan

Re: IsEditor and Editor hasErrors always false problem, and getErrors always empty

There's absolutely no relationship between the Editor framework and JSR303 Bean Validation. That is to say: the Editor framework won't validate your objects, you have to do it yourself (and you can then pass the ConstraintViolations to the EditorDriver for display).

The hasErrors and getErrors only give you errors reported by the editors themselves (e.g. IntegerBox will report an error if you type in something that's not a number).

    public FluidRow getAlertMessageWrapper();

    public Button getSaveButton();

    public Button getSaveGlobalSiteSettingsButton();
    public Button getResetGlobalSiteSettingsButton();

}

ClientConfig.java

package com.hat.coupled.client.domain;

import javax.validation.Valid;
import javax.validation.constraints.Max;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;

public class ClientConfig {
    private Integer siteId;

    @NotNull
    private String textDirection = "ltr";

    @NotNull(message="bla bla bla")
    @Max(10)
    @Size(min = 3, max=10, message="size bla bla bla")
    private String siteName;

    @Size(min=7, max=100)
    @NotNull(message="site email is not set")
    @Pattern(regexp="\\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}\\b", message="email not valid")
    private String siteEmail;

    @Size(min=7, max=100)
    @NotNull(message="site email is not set")
    @Pattern(regexp="\\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}\\b", message="email not valid")
    private String contactEmail;

    private String favicon;

}

Each time, when I try to validate form, for example making Site Name empty i don't get any error message

i am validating using following code in my activity class:

                    ClientConfig config = editor.flush();
                    if (editor.hasErrors()) {
                        Window.alert("has errors");
                        List<EditorError> errors = editor.getErrors();
                        StringBuilder strBuilder = new StringBuilder();
                        for (EditorError error : errors) {
                            strBuilder.append(error.getMessage()).append(error.getAbsolutePath());
                        }
                    } else {
                        saveConfig(config);
                    }

Does anyone know why there are not error messages in editor.getErrors() and editor.hasErrors() is not being set to true.

Thanks,
Milan

gwt rpc generics java.lang.Class

Hi to all,

i am facing a problem with the java generics in rpc. I have implemented a rpc service using the java.lang.class<T> generic and while it works fine when i test it, it cannot be compiled. I have serialized the class that i need to pass through the rpc and i have implemented the default empty constructor but it still does not compile.

Here is my service and the class that i need to pass through the generic.

package com.client.model.mybay.browse;

import java.util.ArrayList;

import com.google.gwt.user.client.rpc.RemoteService;

import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;

import com.shared.source.MySource;

@RemoteServiceRelativePath("categoryService")

public interface CategoryBrowseService extends RemoteService{

ArrayList<MySource> getSourceList(Class<? extends MySource> classType);

}

package com.client.model.mybay.browse;

import java.util.ArrayList;

import com.google.gwt.user.client.rpc.AsyncCallback;

import com.shared.source.MySource;

public interface CategoryBrowseServiceAsync {

void getSourceList(Class<? extends MySource> classType,

AsyncCallback<ArrayList<MySource>> callback);

}

package com.sourcebay.shared.source;

import java.util.Date;

import javax.jdo.annotations.IdGeneratorStrategy;

import javax.jdo.annotations.Inheritance;

import javax.jdo.annotations.InheritanceStrategy;

import javax.jdo.annotations.PersistenceCapable;

import javax.jdo.annotations.Persistent;

import javax.jdo.annotations.PrimaryKey;

import com.google.gwt.user.client.rpc.IsSerializable;

@PersistenceCapable

@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)

public abstract class MySource implements IsSerializable {

@PrimaryKey

@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)

private Long id;

@Persistent

private String userId;

@Persistent

private String title;

@Persistent

private String description;

@Persistent

private String blobKey;

@Persistent

private String youtubeLink;

@Persistent

private String personalLink;

@Persistent

private Date submitedDate;

@Persistent

private float price;

public MySource() {

}

public float getPrice() {

return price;

}

public void setPrice(float price) {

this.price = price;

}

public String getUserId() {

return userId;

}

public void setUserId(String userId) {

this.userId = userId;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public String getDescription() {

return description;

}

public void setDescription(String description) {

this.description = description;

}

public String getBlobKey() {

return blobKey;

}

public void setBlobKey(String blobKey) {

this.blobKey = blobKey;

}

public String getYoutubeLink() {

return youtubeLink;

}

public void setYoutubeLink(String youtubeLink) {

this.youtubeLink = youtubeLink;

}

public String getPersonalLink() {

return personalLink;

}

public void setPersonalLink(String personalLink) {

this.personalLink = personalLink;

}

public Date getSubmitedDate() {

return submitedDate;

}

public void setSubmitedDate(Date submitedDate) {

this.submitedDate = submitedDate;

}

public Long getId() {

return id;

}

I am using AppEngine 1.7.1 and GWT 2.4.0. Does anybody have any idea how to fix this?

Thanks in advance,

Ste
