Pass parameter in jsf, primefaces

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.
