Pass parameter in jsf, primefaces - jsf

Question

I have 2 dialogs. In the 1st dialog user writes modulename and I need to pass my modulename to the second dialog and set this modulename value to bean called #{paramController.parameter.modulename}
Please, give me some ideas how to get parameter from one bean and set it to another bean?

Answer 1

First of all you have a nested tag <h:form>.....<h:form> ... </h:form> </h:form>. You need to get rid of this.
SampleManagedBean1.java
#ManagedBean(name="SampleManagedBean1")
#ViewScoped
public class SampleManagedBean1 {
private String mModuleName = "";
public String getModuleName() {
return mModuleName;
}
public void setModuleName(String moduleName) {
this.mModuleName = moduleName;
}
/**
* invoke this API from UI to set value in this bean
*
* #param moduleName
*/
public void setValueOfModuleName(String moduleName) {
this.mModuleName = moduleName;
}
/**
* Invoke this API from UI to get value from this bean
*
* #return
*/
public String getValueOfModuleName() {
return mModuleName;
}
}
SampleManagedBean2.java
#ManagedBean(name="SampleManagedBean2")
#ViewScoped
public class SampleManagedBean2 {
private String mModuleName = "";
public String getModuleName() {
return mModuleName;
}
public void setModuleName(String moduleName) {
this.mModuleName = moduleName;
}
/**
* invoke this API from UI to set value in this bean
*
* #param moduleName
*/
public void setValueOfModuleName(String moduleName) {
this.mModuleName = moduleName;
}
/**
* Invoke this API from UI to get value from this bean
*
* #return
*/
public String getValueOfModuleName() {
return mModuleName;
}
}
From UI
SampleManagedBean2.setValueOfModuleName(SampleManagedBean1.getValueOfModuleName);

Answer 2

As I understood you have two beans, one for dialog 1 and the second for dialog2.
You can pass the "paramController.parameter" (stored in first bean) as a parameter for method (method inside second bean) which shows dialog2.
