Problem with access modifier during bean model lookup

[goeritz]

Hi!

We have a few problems with using the new bean model in gxt-1.1-alpha3. We want to get some SamObjects via a RPC. This class extends an abstract class AbstractSamObject which is causing some problems because there's a protected getter/setter method in it.

During the compile phase we get this error messages:


Compiling module com.sam.rsc.appstatusview.AppStatusView

I'm not that familiar with the Java Bean Specification but I think the access modifier protected shouldn't cause this problem in this case.
When we replace 'protected' with 'public' everything works very well.

We're using GXT 1.1-alpha3, GWT 1.5.0-rc1 and Windows XP SP3.
Thanks for your answers!

PS: The Java Bean Support is very helpful - thanks Darrell!!



public abstract class AbstractSamObject implements Serializable {

private Integer version;

protected Integer getVersion() {
return version;
}

protected void setVersion(Integer version) {
this.version = version;
}

public AbstractSamObject() {

}

}


public class SamObject extends AbstractSamObject {
/**

private static final long serialVersionUID = 4289225229486590175L;

private Long id;

private String name;

private String siteCode;

private Long rank;

private boolean region;

public SamObject() {
super();
}

public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getSiteCode() {
return siteCode;
}

public void setSiteCode(String siteCode) {
this.siteCode = siteCode;
}

public Long getRank() {
return rank;
}

public void setRank(Long rank) {
this.rank = rank;
}

public boolean isRegion() {
return region;
}

public void setRegion(boolean region) {
this.region = region;
}

}

This could be a bug - the bean model generator creates a new class type for GWT by reflecting the methods as compile/runtime. As such, would probably be best to post in the bugs forum.
