Tobias Glensk commented on TOBAGO-535:
--------------------------------------
An other workaround ist to set the converter id via an f:converter tag
<tx:in label="${item.name}" value="${item.value}">
<f:converter converterId="${item.converterId}" />
</tx:in>
> Possible error resolving EL expressions when using Facelets
> -----------------------------------------------------------
>
> Key: TOBAGO-535
> URL: https://issues.apache.org/jira/browse/TOBAGO-535
> Project: MyFaces Tobago
> Issue Type: Bug
> Components: Facelets
> Affects Versions: 1.0.12
> Reporter: Tobias Glensk
>
> I wanted to set the converter to use for a tx:in from a managed bean, because
> the concrete converter is only known on runtime. My managed bean returns the
> Id for the converter correctly, but I get an error message.
> Example Facelet Snippet:
> <c:forEach items="${controller.currentBean.properties}" var="item">
>
> <!-- 1) below doesn't work, error message: Cannot convert
> de.nordlbit.FDTStringConverter of type class java.lang.String to interface
> javax.faces.convert.Converter -->
> <tc:in label="${item.name}" value="${item.value}"
> converter="${item.converterId}" />
> <!-- 2) below doesn't work, error message: Cannot convert
> de.nordlbit.FDTStringConverter of type class java.lang.String to interface
> javax.faces.convert.Converter -->
> <c:set var="converterId" value="${item.converterId}" />
> <tc:in label="${item.name}" value="${item.value}"
> converter="${converterId}" />
>
> <!--3) below works, setting String statically -->
> <tx:in label="${item.name}" value="${item.value}"
> converter="de.nordlbit.FDTStringConverter" />
> </c:forEach>
> ${item.converterId} returns a String with the value
> "de.nordlbit.FDTStringConverter ". Using the examples 1 and 2 I get an error
> message, setting the same String like in example 3 statically, it works. The
> error message / stacktrace returns for the examples 1 and 2:

> Example Snippet from the managed bean item class
> /**

> public String getConverterId() {
> return this.converterId;

> I tried to use # instead of $ but the same behaviour can be observed.
> The help for the converter attribute states:
> An expression that specifies the Converter for this component. If the value
> binding expression is a String, the String is used as an ID to look up a
> Converter. If the value binding expression is a Converter, uses that instance
> as the converter. The value can either be a static value (ID case only) or an
> EL expression
