ComponentParameter value to Persistent ComponentProperty
I have found several posts here where this problem is discribed.. but
"no one" works in my case...
One described: Overwrite the pageBeginRender ... i tried but i use a
@For-Component so that this doesnt work because the property is persistent.
Error ("Change to persistent property ... has been ignored. Persistent
properties may only be changed prior to the rendering of the response page."
)
Another one make use of a bean... I also tried this... overwriting the
bean-value with the parameter value in the pageBeginRender method but this
also throws an error. in correspondending abstract class i make use of the
property normally generated on rendering (discribed here
http://tapestry.apache.org/tapestry4.1/usersguide/spec.html ->bean
specification).
This throw also an error "ognl.NoSuchPropertyException
org.apache.tapestry.bean.BeanProvider.persistItem "
Here my bean specification:
<bean name="persistItemBean" lifecycle="page" property="persistItem"
class="myobject"></bean>
Has anyone an idea... or better a solution??? ^^

Re: ComponentParameter value to Persistent ComponentProperty
Posted by Skorpien126 <lo...@web.de>.
Ok I tried it very often ... and it looked like that
page:
...
<span jwcid="@Foreach" source="ognl:MyList" value="ognl:TemporaryItem"
index="ognl:Index">
<span jwcid="@If" condition="ognl:MyClass">
<span jwcid="@MyFormComponent"
item="ognl:TemporaryItem"/>
</span>
</span>
...
myformcomponent.jwc
...
<component id="putitin" type="TextArea">
<binding name="value" value="ognl:item.content"/>
</component>
<!-- Parameter -->
<parameter name="item" required="yes"/>
...
myformcomponent.html
<form jwcid="test@Form" listener="listener:formSubmit">
<textarea jwcid="putitin" cols="70" rows="10">
Content...
</textarea>
<input type="submit" value="Send"/>
</form>
Reading the Parameter was no problem but when I submit the form i get an
"setProperty(null,content,"my new value exception)"... I my eyes it looks
like that the binding wasn´t successfull.
I read several forum-messages ... some of them with the same problem. They
all give the parameter to a persistent property.

Oh yeah... this was my first Idea,too ... after reading tapestry in action.
but using parameter is not possible because the parameters ( in my case )
are propertys of an object which itself is put in a persist collection. I
guess that tapestry can´t bind objects of an collection.... ?!?!?!?

Generally speaking you really ~don't~ want to store persistent fields in a
component if you can help it. Make everything a parameter.

SOLVED:
created a bean .... but not using the property-attribute of the bean tag...
instead i make use of getBeans().getBean("beanname")... SURELY not the most
intuitiv way... an lot of casting around but it seems to work!!
