Workaround on jsFunction + actionparam

[leiras]

Hi all, i have the following code:

<a4j:commandLink id="cm1" onclick="javascript:showParameter('abc');" value="test"/>

<a4j:jsFunction name="showParameter" actionListener="#{telaCodigo.showTestParameter}">
<a4j:actionparam name="param1" assignTo="#{telaCodigo.testParameter}" />
</a4j:jsFunction>


public void showTestParameter(ActionEvent event) throws Exception {
System.out.println(this.testParameter);
}

When i click on commandLink, the value 'abc' should be assigned to telaCodigo.testParameter.
But this happens only after the second click. On the first click, the value of telaCodigo.testParameter is null.
I read some thing about a workaround to fix it.
Could anyone explain me how can i do that?
Thanks a lot!

Hello,

Use either actionListener attribute of a4j:actionparam tag or add your listener after a4j:actionparam using f:actionListener tag.

Thanks a lot nbelaevski!
Here is the final code:

<a4j:commandLink id="cm1" onclick="javascript:showParameter('abc');" value="test"/>

<a4j:jsFunction name="showParameter">
<a4j:actionparam name="param1" assignTo="#{telaCodigo.testParameter}" actionListener="#{telaCodigo.showTestParameter}" />
</a4j:jsFunction>
