Question

I have an xml file that has a start date and length of a project… I use a repeater to load each project. The users’ screen only shows 2 weeks at a time. I would like to make it so that if a project doesn’t fall within the two weeks on screen, that the project isn’t loaded. I could do this by sorting through the XML and finding the correct projects to load, and putting them into an array collection, but there’s a “move date” button which allows the user to change the two weeks that are showed. Once the two weeks are changed, I would need the projects that fit into that new 2 week window to show.

Currently, my repeater looks like this:

<mx:Repeater id="projectRP" dataProvider="{projectsHttp.lastResult.project}" recycleChildren="true">
    <Block:project id="wholeProject"
        dbID="{Number(projectRP.currentItem.dbID)}"
        projectID="{projectRP.currentIndex}"
        workingTitle="{projectRP.currentItem.workingTitle}"
        projectTitle="{projectRP.currentItem.projName}"
        startDate="{textToDate(projectRP.currentItem.startDate)}"
        projectPositions="{XML(projectRP.currentItem.positions)}"
    />
</mx:Repeater>

Any help would be greatly appreciated!

You can’t do this with a repeater, and I believe we’ve told you several times before not to use a repeater. If anything, filter the data and either do runtime adding of the project or use a List of some sort.

If you’re using a List, filter would work automatically. If you’re using runtime adding, you’ll need to listen for the collection change event on the ArrayCollection and do your own algorithm.
