Error in conversion Java Object to JavaScript

[mabaumga]

Hi all,

after a click on the following commandButton:

<a4j:commandButton actionListener="#{PageManager.click}"
value="Hoch" data="#{item}"
image="/cms/icons/Up16.gif" />

I get this error:

I can debug into the ActionListener Function so it that the error occurs somewhere on the way back.

Has anybody a hint?

Hm, I have no attribute "actualMaximum" in my JSF.....

[nbelaevski]

Hello,

Try removing data="#{item}" attribute.

[mabaumga]

Hm, but how can I get in this case the reference to the data object? I use the commandButton within a rich:dataTable and would like to do an action on the record of every row.

[mabaumga]

Okay, I got my mistake: The data object was not serializable. Maybe there should be a check and a better understanding exception?

Shall I fill in an jira issue?
