ComboBox Change listener

[kingbee888]

Hi All,

I created multiple custom Form Types that are combo boxes and I need to change the data of one based on the value of another but I'm not really sure how to do so.  I know that I have to implement the addListener(new Property.ValueChangeListener()  method but how do you reference the other custom Form type?  Or will I have to create a custom field that contains all the comboboxes? 

If someone can point me to an example on how to implement this, that would be great.


Thanks,
Bee

The second indeed would need to depend on the first one and add a value change listener.

Renderers of form types are defined in the activiti-ui-context.xml:

<code>
<property name="propertyRenderers">
      <list>
        <bean class="org.activiti.explorer.ui.form.StringFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.EnumFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.LongFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.DoubleFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.DateFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.UserFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.BooleanFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.ProcessDefinitionFormPropertyRenderer" />
        <bean class="org.activiti.explorer.ui.form.MonthFormPropertyRenderer" />
      </list>
    </property>
</code>

Adding your custom type there that depends on the other is done there.

Hello,

Ok, this may answer the question, going with the second option of building a custom component with all the combos. But this is, honestly speaking,  unnatural.

Suppose, for example, I have a form for booking a travel in a yacht, and depending on the count of passengers, the maintenance status and the availability of the company boats the yatch combo is filled, do i have to put all the passenger count, status and booking dates fields all of them in a single custom component?

What do we have to do to change this?
