Para passar parametro dinamicos para o linkTo, como é feito?

Assim funciona:

<div id="gallery">
	<c:forEach items="${imagemList}" var="img">
		<img alt="Foto" src="${linkTo[ImagemController].fotoDaAcomodacao}${img.id}" />
	</c:forEach>
</div>

Assim não:

<div id="gallery">
	<c:forEach items="${imagemList}" var="img">
		<img alt="Foto" src="${linkTo[ImagemController].fotoDaAcomodacao[${img.id}]}" />
	</c:forEach>
</div>

O correto é assim: ${linkTo[RateController].edit[item.id]}

Sendo RateController o nome da classe Resource, edit o método, item é meu objeto, id a propriedade.

Mesmo se eu colocar um valor fixo por exemplo: 
${linkTo[ImagemController].fotoDaAcomodacao[71]}
Da o mesmo erro.

garcia-jj

O mesmo erro certamente não é. Talvez um parecido. Olha a mensagem de erro:

Could not find getter for field id

Você tem essa propriedade e um getter para ela?

Sim tenho, tanto é que se eu fizer conforme abaixo funciona:

Lucas_Cavalcanti

se a lógica recebe uma img, vc tem que passar uma img, não um id:

${linkTo[ImagemController].fotoDaAcomodacao[img]}

#olocomeu, ai sim em.
