I am using Apache Tiles 2.1 as my templating framework (along with Spring MVC).

I want to know how best to be able to set HTML attribute values from within my Tiles definitions file. For example I have a text box and want to be able to set the maxlength attribute from within my definition. I expected the following to work -

<input id="nameField" type="text"
    maxlength="<tiles:insertAttribute name='maxlength' />" />

using this definition - 

<definition name="sprint-goal" >
       <put-attribute name="maxlength" value="100" />
</definition>

But it seems that Tiles ignores the <insertAttribute/> tag if placed within a HTML tag. It works fine otherwise.

Note: I have tried using a ViewPreparer to set request-scoped values. This will work but is not exactly what I am looking for. I would like to easily set HTML attribute values from within a Tiles definition.

To set the value of html element attributes, your best bet is to use Expression Language. First, expose the tile attribute as a java variable using the tiles useAttribute tag. Then use '${}' to print the variable.

Example:

<tiles:useAttribute name="myMaxLength" id="maxLength" />

<input id="nameField" type="text" maxlength="${myMaxLength}" />

 <put-attribute name="maxlength" value="100" type="string" />
