Can't pass boolean parms in componentControl

[pdpantages]

Hello Forum,

I am using:
Jboss 4.2.2.GA
Seam 2.0.1.GA
Richfaces 3.1.6.GA

I was trying to use componentControl with a context menu inside a rich:tree.

I can't seem to pass a boolean value true/false to the menu for use in the
menuItem's disabled attribute.

My component control is like so.

<rich:treeNode rendered="#{node.nodeType == node.nodeTypeNe}" iconLeaf="/img/ne16.png">
 ....
 ....
 <rich:componentControl
 event="oncontextmenu"
 for="em" operation="show">
 <f:param value="#{node.description}" name="nm"/>
 <f:param value="#{node.id}" name="id"/>
 <f:param value="#{node.craftUrl}" name="crft"/>
 <f:param value="#{node.craftUrl == null ? true : false }" name="nocrft"/>
 </rich:componentControl>
</rich:treeNode>

Inside my context menu, I use the value of "nocrft" to disable one
of the menu items.

<rich:contextMenu id="em" attached="false" submitMode="ajax">
 ....

 <rich:menuItem
 value="Launch Craft {nocrft}"
 disabled="{nocrft}"
 onclick="window.open('{crft}','_blank')">
 </rich:menuItem>

 ....

The menuItem is never disabled. I tried single quotes 'true' and 'false' and
hard coding "true" for the f:paraemter nocrft, but the menuItem is never
disabled.

I put the {nocrft} in the value string to see what it was, and it
is in fact "true" when expected....

The answer is probably very simple, but somehow is eluding me.....

Any help will be appreciated.

Thanks, PdP

I have the exact same problem. The big question is "Can we affect the component attributes with the parameters passed from componentControl or just the content of the component inside the menuItem.

This is driving me crazy :( and no solution so far

Hello k2kirov,

No, I have not found a solution; I have been distracted with some memory leak issues and have not returned to look at this one. I thought that, in my case, I might be able to write some javascript to set the "disabled" attribute and call it on the onshow event, but I have not tried this.

I will definitely post if I can get anything to work.

Just the content. A possible workaround is to create two menu items: one disabled another not and make one of them hidden by using style="display: {someParam}" declaration where someParam can be set to 'none' or ''.

Thank you nick, the workaround fixed me up.

k2kirov, hope this helps you. I used something like this for my componentControl:

<rich:componentControl
 event="oncontextmenu"
 attachTiming="onload"
 for="em" operation="show">
 <f:param value="#{node.description}" name="nm"/>
 <f:param value="#{node.id}" name="id"/>
 <f:param value="#{node.craftUrl}" name="crft"/>
 <f:param value="#{node.craftUrl == null ? 'block' : 'none' }" name="cd"/>
 <f:param value="#{node.craftUrl == null ? 'none' : 'block' }" name="ce"/>
</rich:componentControl>

I used 'block' intstead of '' to avoid FF css errors about invalid style.

In the context menu:

<rich:menuItem
 style="display: {cd};"
 value="Launch Craft"
 disabled="true"
 submitMode="none">
</rich:menuItem>
<rich:menuItem
 style="display: {ce};"
 value="Launch Craft"
 disabled="false"
 onclick="launchcrft('{crft}');">
</rich:menuItem>
