Force jsf clientid

Question

Hi,
I created a custom JSF 1.1 component. Just like the Tomahawk component set I would like to be able to force the clientId to be the value I specify in the id attribute of my custom tag using an extra 'forceId' attribute. This works fine when I don't use valuebinding for this id attribute. But it seems that valuebinding is not allowed for the id attribute because it is ignored when I use a value like 'xxx#{yyy}'. To fix this I assumed that I needed to modify my setProperties() method of my JSF UIComponentTag. But when using Facelets this class is never called: I guess because Facelets uses it's own TagHandler?
Why does Facelets ignore the valuebinding used in the id attribute?
Does anyone have a suggestion to deal with this problem? Do I have to create a custom TagHandler?
Thanks in advance!
Kind regards,
Dirk

Answer 1

Hi,
suppose I have the following HTML rendered:
<tr>
<td>
<input type="radio" id="form:tab1:tabSubForm1:choices:0:mc_choice1308" name="choices_question608" value="1308">
</input>
</td>
<td>
<img src="/Fysiquest/protected/documentServlet?id=12105" />
</td>
</tr>
<tr>
<td>
<input type="radio" id="form:tab1:tabSubForm1:choices:0:mc_choice1309" name="choices_question608" value="1309">
</input>
</td>
<td>
<img src="/Fysiquest/protected/documentServlet?id=12107" />
</td>
</tr>
if I want the radiobutton to be selected when the user clicks the image it seems more handy to me to only specify 'mc_choice1308' or 'mc_choice1309'. My page contains multiple tabs (cfr 'tab1') and I even can't render the '1308' or '1309' after the 'mc_choice' because JSF EL for the id attribute is not working. So, it does not matter if I just want 'mc_choice1308' or 'form:tab1:tabSubForm1:choices:0:mc_choice1308': I just want the JSF EL to work with the id attribute.
Kind regards,
Dirk
