The MAX_WIDGET_TREE_DEPTH is set to 1000, where the TW UI for some elements may use up to 150 or so. If users mess up templates the limit 1000 seems to be too high. It can “brick” the UI for quite some time. So we did discuss to lower the limit.
For recursions that are well defined, like the example here, the limit seems to be to low. It may be possible to define a tv-max-widget-tree-depth variable that can overwrite the hardcoded limit.
just some thoughts.
