Thanks for all your help Thiago. I'm not trying to render all fields in the grid as form fields, just the one from my custom component X that's a property of bom Y, and a selection of other properties of bom Y that are plain Strings, Integers etc., which the grid handles perfectly just using t:param and input fields. I have what I need working by creating a PropertyEditContext in the beginRender method of the custom component whenever it is being rendered as part of a grid, pushing it to the environment, and popping it in the afterRender method. Hopefully this doesn't set off any alarm bells.
I like the idea of being able to use the overrides to achieve something similar, though it does put the onus on the developer to make the override available as a property in every page where a relevant grid occurs <I think>. I'll have a look into it when I'm not so stretched for time. Thanks again.

You don't need a list of PropertyOverrides, just one. Grid (more specifically, GridCell) asks to the override if it provides a block for rendering the property (overrides.getOverrideBlock(blockId). If it returns null, it uses the BeanBlockSource service to get one. > - I'm guessing this behavior is not what I want as I just want to affect > rendering for this specific field, < <t:myCustomComponent > value="bom.property"/>? Use a <p:xxxCell> or <t:parameter name="xxxCell"> tag. I thought you were trying to render all grid cells as form fields. -- Thiago H. de Paula Figueiredo Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor Owner, Ars Machina Tecnologia da Informa��o Ltda. http://www.arsmachina.com.br --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
