link in header of dataTable

[banifou]

Hello,

when I put a commandLink into <f:facet name="header"> after clicking that link I get an Exception:

java.lang.IllegalArgumentException: class org.springframework.faces.model.OneSelectionTrackingListDataModel is in an illegal state - no row is available at the current index.

I'm using SWF-2.0.1 with Facelets.

Does anybody know if this a bug is?

Thanks a lot

Hmmm...yes, looks like a bug to me. Can you open a Jira? Thanks.

[banifou]

How can I do that?

Welcome to the Spring communty :-)

[banifou]

I' ve created my first jira issue (SWF-692).

By the way, how can I overcome this problem?

Thanks

For the time being you could use result-type="org.springframework.faces.model.Serializable ListDataModel" in your <evaluate> expression that loads the data for the table. This would get rid of the error...the only drawback is that you will lost the ability to have "model.selectedRow" type of expressions like what we have in the booking-faces sample.

The fix for the larger problem is pretty simple and I should get it committed today, so you could potentially use tonight's nightly build to get the fix.

The commandLink is working fine in dataTable even the ability to have "model.selectedRow", but outside <f:facet name="header">.

It seems that SerializableListDataModel tries to get selectedRow even when the link is in the header of the dataTable. But there isn't any index.

I tried to put a "selectedRow" inside the method (e.g. switch order of a list) without using it. The error disappears but the transition doesn't occur and that is very unfortunate.

Ok, I just committed a fix for this. Try tonight's nightly build to ensure it solves the problem as expected.

[banifou]

OK, thank you very much.

So, I tried the nightly build(swf 2.0.2). There is no error more. But the commandLink is not working inside the <f:facet name="header">. After clicking on the link nothing happened. The SWF transition doesn't occur, in my case, refreshing the flow by sorting new the dataTable.

When I put the same link with the same method outside the "dataTable" the transition occur and the flow is refreshed.
