freemarker templating

Hi,

I have a hierarchical list of research items that i use a recursive function to build the list and then return this to a .htm page.

i then use a freemarker macro to display the list using
    and
  • tags.

    The problem is at the moment the code that displays the list has hard coded #assign statements for each level but i want the code to work regardless of the number of levels in the list.

    Is there a way i can dynamically create variables depending on the number of levels? e.g.



    where the variable names are 'count1', 'count2', 'count3', etc.

    Hope this makes sense?

    Liam

HHHm... never tried this. I suggest looking at the manual of freemarker, at http://freemarker.sf.net

If you find anything, let us know

May be try this code. Or see the interpret built-ins in Freemarker manual.

I tried the code:

<#assign ResetCountTemplateSource="<#assign count${a} = 0 />" >
<#assign ResetCountTemplate=ResetCountTemplateSource?interpret >
<#list 0..depthOfList as a>
<@ResetCount />
</#list>



but couldn't get it to work so i tried the example on the freemarker documentation

<#assign x=["a", "b", "c"]>
<#assign templateSource = "<#list x as y>${y}</#list>">
<#assign inlineTemplate = templateSource?interpret>
<@inlineTemplate>def</@inlineTemplate>



http://freemarker.sourceforge.net/docs/ref_builtins_expert.html

And this doesn't work either, it says y is undefined.

Any ideas? I appreciate your help.

Hello liam,

I am very sorry. The code I post before is wrong.

Please try the following one.

Hi,

I have a new problem.

I have a hierarchical list and i want to disable all children of a branch.



e.g. i want to disable fruit and all children of fruit.

Is there a way I can add ids to an array or list and then check if they exist to determine whether or not to display an item?

Liam
