Triggering a partial update on a grid
I have a search form and a grid with the results.
I'd like to submit the form and update the grid with the filtered
results without doing a full page refresh.
My take on this is to set the form component "zone" parameter to the
grid zone id so that the form submit it's treated "AJAX way" and the
submission triggers the grid zone to get updated. The form submit event
handler method filters the search results, changes the property that the
grid uses as datasource and returns the Grid component itself.
This strangely enough only works the first time i perform the search.
From there on i always get an exception when i click the search button,
that seems to be related to the fact that the Grid doesn't acknowledge
that the datasource size has changed. Here's the stack trace:
Caused by: java.lang.IndexOutOfBoundsException: Index: 10, Size: 10
at java.util.ArrayList.RangeCheck(ArrayList.java:547)

Any ideas would be most welcome.
Thanks.

That could be problem.
I can see that the grid is using CachingDataSource for caching the
dataSource size. But i see no way to invalidate that cache.

from the above stack trace seems like the DataSource was cached right?
could that be the problem?

Yep, i have it implemented like that. Forgot to rollback some changes
that i tried to make this work before putting the code in the post. Sorry.
With a zone just outside the grid and setting the form to update it i'm
still getting the exception.

Maybe not related to your problem, but the zone parameter of the Form
component must be the id of a *zone*. You're passing it the id of a
*grid*. I would try to put the grid inside a zone and then update the
zone. ;)

I thought so too, but i'm starting to think there is one.
Here's some of the code in hope someone will spot something wrong:
template:
<div t:type="form" t:id="filterForm" zone="processGrid">
<!-- the filter inputs and stuff -->
<div t:type="buttons/genericbutton" label="message:filter"
submit="true"/>
<div t:type="eventlink" event="linkTest"
zone="processGrid">Search</div>
<div t:type="grid" t:id="processGrid" source="processes"
inplace="true" rowsPerPage="prop:gridRowsPerPage" row="currentProcess"
rowClass="rowClass"
exclude="${message:proccessListExclusionColumns}"
reorder="${message:proccessListColumnOrder}"/>
</div>
on the class:
@OnEvent(value = "submit", component = "filterForm")
Grid filter() {
processes.remove(0);
return processGrid;
}
Grid linkTest() {
processes.remove(0);
return processGrid;
}
If i press the eventlink eveything goes fine, if i use the submit button
i get the exception.

Re: Triggering a partial update on a grid
Posted by Hugo Palma <hu...@gmail.com>.
I had thought of that.
But all the form parameters are persisted and i have debugged the
application and the grid source parameter has the correct size. Only the
grid doesn't seem to be aware of it.
I just found out that if i use an eventlink component to trigger the
update instead of the form submit it works just fine. Obviously the form
parameters aren't updated but i put some code on the event handler that
filters the source anyway. No exception this way.
What's the difference between using the form submit with a zone and
using an event link besides the form parameters not getting updated ?

Take a look at the collection returned to the Grid source parameter in the
second request. One common error is to not @Persist the form parameters.
Then, when you request the n+1 page, the form parameters are lost and the
search made is not the same as the first one.
