I am working on extension in which i have add sales rules conditions in my ui form. I am storing as serialised condition. it saves perfectly. However, i am getting empty field during edit form.

This is my code: I have add following code in my ui form:

<fieldset name="serialized_condition">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="label" xsi:type="string" translate="true">Conditions</item>
            <item name="collapsible" xsi:type="boolean">true</item>
            <item name="sortOrder" xsi:type="number">20</item>
        </item>
    </argument>
    <container name="serialized_condition" >
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="sortOrder" xsi:type="number">10</item>
            </item>
        </argument>
        <htmlContent name="html_content">
            <argument name="block" xsi:type="object">Company\Module\Block\Adminhtml\Module\Edit\Conditions</argument>
        </htmlContent>
    </container>
    </fieldset>

This is block file Conditions.php:

  • Sounds weird, and likely not the issue, but maybe try starting the namespace (line 5) on line 2 and add a space after <?php instead of the 4 /r before line 5. Like I said, probably not it, but I swear I think I had something similar and it ended up being the space "<?php " that fixed my problem.
