Partial update dynamic view on CustomControl | XPages

Question

I have an application with one XPage. It has these custom controls(cc):

ccHeader
ccMenu
ccContent
ccFooter

Custom control ccContent has a combobox, with list of Views in sessionScope and dynamic view panel from extension library for XPages. This combobox has an event OnChange defined to partial update dynamic view.

What do I need?: Combobox with view list will be deleted and after that I need to assign this partial update function to five links, which are located on ccMenu custom control. So, i click on link in ccMenu, it returns some view name, assigns it to dynamic view and makes partial update.

How to get id of this dynamic view in ccMenu to call partial update?

Please, post code sample. And I don't get it: can you rephrase your last sentence, please? — Frantisek Kossuth

Assuming what you mean is that you want to have a clean way to let the buttons know which area to partial-refresh when changed:

You could add a property to the ccMenu control along the lines of "viewRefreshId" and pass in the ID of the area to refresh, so you'd end up with a button like this:

<xp:button id="viewChanger1" value="View 1">
    <xp:eventHandler event="onclick" submit="true" refreshMode="partial" refreshId="${compositeData.viewRefreshId}">
        <xp:this.action><![CDATA[#{javascript: viewScope.selectedView = 'View 1' }]]></xp:this.action>
    </xp:eventHandler>
</xp:button>

Now, there's a question of whether you should try to pass in an ID from something contained within another CC from the main XPage, and I try to avoid that - it would PROBABLY work, but it's a bit messy. I tend to architect similar things so that the part to be refreshed is directly on the XPage (which is to say, I don't use "content" custom controls), so I end up with something like this:

<xc:viewSelector viewRefreshId="dynamicViewContainer"/>

<xp:div id="dynamicViewContainer">
    <xe:dynamicView>
        <xe:this.data>
            <xp:dominoView var="view1" viewName="#{viewScope.selectedView}"/>
        </xe:this.data>
    </xe:dynamicView>
</xp:div>

The extra container div comes from experience that I had a while ago where refreshing the dynamic view directly caused rendering problems, but I don't know if that's still the case (or if I had run into some other problem).
