Complicated grid-relationship-grid parsing issue.

[robinsowell]

Have an entry with a grid field. One of the columns is a relationship.

The related entry has a grid field with a text field and an image field.

This works:

{exp:channel:entries channel="pages" entry_id="1"}
        
{main_grid}

  <h2>block {main_grid:row_id} {main_grid:title}</h2>
  
{main_grid:sliderrel}		

related slider entry title:{main_grid:sliderrel:title}<br><br>
slider images: 
 {main_grid:sliderrel:slider}
 slider image title: {main_grid:sliderrel:slider:title}<br>
  {main_grid:sliderrel:slider:image}
      URL: {url}<br>
  {/main_grid:sliderrel:slider:image}
{/main_grid:sliderrel:slider}
{/main_grid:sliderrel}

{/main_grid}

{/exp:channel:entries}'

If you use the main_grid tag more than once? It does not work, only the first one shows anything and the rest is blank. Template code:

{exp:channel:entries channel="pages" entry_id="1"}
        
             {main_grid row_id="5"}

   <h2>block id 5 {main_grid:title}</h2>
  
 {main_grid:sliderrel}		

 related slider entry title:{main_grid:sliderrel:title}<br><br>
 slider images: 
  {main_grid:sliderrel:slider}
  slider image title: {main_grid:sliderrel:slider:title}<br>
   {main_grid:sliderrel:slider:image}
       URL: {url}<br>
   {/main_grid:sliderrel:slider:image}
 {/main_grid:sliderrel:slider}
 {/main_grid:sliderrel}

 {if main_grid:buttons != ""}
 block buttons:<br>
 {main_grid:buttons}
 {/if}

 {/main_grid} 

            
 {main_grid row_id="1"}
 <h2>block id 1 {main_grid:title}</h2>            			
      {main_grid:image} -{main_grid:title}
 {/main_grid} 
           
 {main_grid row_id="2"}
  <h2>block id 2 {main_grid:title}</h2>
 {/main_grid}

 {main_grid row_id="3"}
 {/main_grid}


 {main_grid}ALL main_grid id/title: {main_grid:row_id} -- {main_grid:title}<br />{/main_grid}

This might (or might not) be related to #1036 and #787

This is related to the fact that Grid field is taking entry_id based on $this->row object that is set by channel parser. So when Grid in related entry is parser, the entry_id is reset. And then when original entry's Grid is about to be parsed, the row cannot be found, because wrong entry_id is passed.

I think we need to either:

• not use $this->row in Grid field at all but have another way to pass entry ID
• reset the $this->row after Relationship parser finishes its work (and preferrably without making Channel Entries parser go through whole process again)

So far, I wasn't able to figure out how to do any of those. Maybe there's another more simple solution, so I need someone else to have a look.

I'm wondering if there any news about this?

I am experiencing issue with grids where adding one more grid call breaks totally different grid. It's frustrating!

I believe we did not look into in since when the last comment was made. @bryannielsen perhaps you could spend couple of hours investigating this at some point

Wow, now it's even not a grid call. I am adding just one more {field} in a template - and one of my grids is breaking.

So, I decided to take a closer look why this exact grid call is breaking and not any others. So, here is the code:

{if "{film_filmmakers_grid:total_rows search:film_filmmaker_production_role='Director'}" <= 2}
  {film_filmmakers_grid search:film_filmmaker_production_role='Director' backspace='2'}
      {film_filmmakers_grid:film_filmmaker_relationship:filmmaker_en_name:trim}, {/film_filmmakers_grid}
{if:else}
  {film_filmmakers_grid search:film_filmmaker_production_role='Director' limit='1'}
    {film_filmmakers_grid:film_filmmaker_relationship:filmmaker_en_name:trim} and {exp:mx_calc expression="{film_filmmakers_grid:field_total_rows}-1"} others
  {/film_filmmakers_grid}
{/if}

It looks like this part is problematic:

{film_filmmakers_grid:total_rows search:film_filmmaker_production_role='Director'}

When I remove the search part of it search:film_filmmaker_production_role='Director', it stops breaking.

By "breaking" I mean this:
