Refreshing tapestry grid content from another component.

[abangkis]

Hello, in tapestry 5.4 it's very easy to refresh the grid content using
ajax. You just set inplace field to true and you're done.  The grid
component handles everything.

Now I'm wondering if there's any way to trigger this behavior from another
component.

For example i have an UpEvent link that is inside the grid, that will move
the order of the content. When it's clicked the database will be update and
i expect the grid to be refreshed partially. I could create a zone that
wrap the grid and re-render it using ajax renderer. But I'm wondering if i
could just use the existing grid internal zone instead.

Thank you verymuch.

Have you thought about wrapping it in a Zone?

Hi Thiago, thanks for the reply. Yes, after a few try I finally just wrap
the whole grid component in a zone.

I tried
triggering resources.triggerEvent(InternalConstants.GRID_INPLACE_UPDATE,
null, null); from onUpEvent, that trigger from an event link inside the
grid. But that didn't seem to work :)

This is a common misconception. Your eventlink "inside" the grid is not a
child of the grid so the event won't bubble up to the grid. GridRows and
GridColumns are children of the grid component, blocks defined in your page
are not. This can be counterintuitive sometimes because the eventlink is a
child in the clientside dom/html but not in the serverside component model.

Hi Lance, thanks for the explanation :)

Spot-on explanation, Lance. We could try to find some client-side  
JavaScript event that triggers that, but I'm in the middle of a work fire  
here . . . :(
