I have a probleem when trying to layout my grid. Actually it should have one header row and one header column. The number of possible rows AND columns are dynamic.
A short eaxmple: (left all out what is not relevant)
<grid model="@bind(vm.listPermissionRows)">
<columns>
<column hflex="2" label="Subjects" />
<column forEach="${vm.listActions}" label="${each.name}" />
</columns>
<rows>
<template name="model" var="prow">
<row children="@bind(prow.permissionList) @template('created')">
<!-- THIS DOESNT SHOW UP -->
<label value="@load(prow.subjectName)" />
<template name="created" var="pm">
<label value="dummy"/>
</template>
</row>
</template>
</rows>
</grid>
As you can see, this doesnt work, the label will be ignored, only the template is beeing used. But how to solve my problem? I cant use a div as a wrapper for my children, as this would group all items in one column. I am clueless. Any ideas?
With inclusion of a column model I can suggest the following solution. A little esoteric, but maybe useful for inspiration.

Current template children binding doesn't support this usage. If the value won't change, please using forEach.
<row>
<label value="@load(prow.subjectName)" />
<zk forEach="@load(prow.permissionList)">
<label value="dummy"/>
</zk>
</row>

I tried <ZK>...</ZK>... the zk part is ignored completely :(
GEdelmann ( 2013-01-31 16:57:22 +0800 )editchildren-binding will clear first then generate and template basically is not a component (more like a definition), so children-binding has no information to know where(which position) to create the children
