I was also facing the same issue. It helped me a lot &lt;span class="emoticon" data-url="https://community.appian.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile"&gt;&amp;#x1f642;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Rule "I" has 1 parameters, but passed 0</title><link>https://community.appian.com/thread/72053?ContentTypeID=1</link><pubDate>Wed, 12 Feb 2020 12:24:04 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:dee7254f-d7a4-48bd-b011-b21bd452732c</guid><dc:creator>varunkumarb0001</dc:creator><description>&lt;p&gt;Found the resolution, so closing the issue. On debugging, problem was with validation code&lt;/p&gt;
&lt;p&gt;validations: {&lt;br /&gt; a!forEach(&lt;br /&gt; items: ri!requestTypeRef,&lt;br /&gt; expression: if(&lt;br /&gt; or(&lt;br /&gt; isnull(&lt;br /&gt; ri!requestTypeRef[fv!index].RequestTypeName&lt;br /&gt; ),&lt;br /&gt; isnull(&lt;br /&gt; ri!request[fv!index].Quantity&lt;br /&gt; ),&lt;br /&gt; isnull(&lt;br /&gt; ri!request[fv!index].Price&lt;br /&gt; ),&lt;br /&gt; isnull(&lt;br /&gt; ri!comment[fv!index].Comment&lt;br /&gt; )&lt;br /&gt; ),&lt;br /&gt; a!validationMessage(&lt;br /&gt; message: &amp;quot;Please fill all the Required* fields!&amp;quot;,&lt;br /&gt; validateAfter: &amp;quot;SUBMIT&amp;quot;&lt;br /&gt; ),&lt;br /&gt; &lt;strong&gt;&amp;quot;replaced {} with a!validationMessage()&amp;quot;&amp;nbsp;&lt;/strong&gt;&lt;br /&gt; )&lt;/p&gt;
&lt;p&gt;On following the exact SAIL Recipe for validations... &amp;quot;&lt;span&gt;Showing Validation Errors that Aren&amp;#39;t Specific to One Component&amp;quot;, I found that Appian gives error on&amp;nbsp;using blank braces, something needs to be there, either an empty string &amp;quot;&amp;quot; but not {}, it was weird and time consuming.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
